@Ryan Gouse. First of all, thank you very much for your comment! If we are talking about the central console of the car, my recommendation is to make a mold from CSM and polyester resin. As a benefit, these are the cheapest components in the composites industry. Then infuse with a vacuum pump in this mold using carbon fiber and epoxy resin. The result will exceed expectations. Like pros and cons, polyester resin releases styrene at least months after the reaction becomes inert. If you do not have a problem with the smell generated by this, for a period of time, I recommend using polyester resin because it is much cheaper. Epoxy resin is more expensive but does not release any smell after the reaction becomes inert. And it is clear transparent if you want to use carbon fiber. If you want to paint the console, there is no point in using carbon fiber, but the only problem will be the smell of styrene, combined with that of paint. After so many years of working in this field, I'm somehow immune and it doesn't bother me personally. I just don't feel it anymore. But I have friends who draw my attention when they get into my car. Because I have some elements in the car that are made out of fiberglass. Hoping that my answer was helpful, I encourage you to move forward with your project. And if you have more questions, don't hesitate to contact me. Last but not least, thank you very much for your support. This motivates me and gives me satisfaction that my work is appreciated.

@@PAFixandCrafts Thank you so much for the detailed and helpful response! Unfortunately I was referring to a center console for a Boat, I am sorry I should have been more clear! The center console acts as the steering helm and is around 3' tall x 3' deep and 3' wide. Like I said the structure is pretty solid so I am fiberglassing for waterproofing needs! But will also want some additional strength. I think I want to work with chopped strand as It seems most forgiving to work with for first timer. Would you have any tips? Should I use epoxy or polyester resin? I am mainly concerned with having a good bond with the 1/2 plywood soaking up the resin and becoming more waterproof. I have radius all the edges with a 3/4 roundover bit so I hope that helps with no sharp edges Thank you again for all the help!

First of all, thank you very much for the comment. I only use short hair rollers made of polyamide. As tips, before you start laminating or applying gelcoat, blow the roller with the compressed air gun. It will remove most of the hair that will fall out during rolling.

@ Sorin Baiatu. Daca te referi la rolele de trafalet, pe acestea nu le curat. Pentru mine sunt materiale de unica folosinta. Este doar o chestie personala. Insa acestea pot fi curatate cu Rhodiasolv IRIS de aproximativ 2-3 ori, in cazul in care optezi pentru varianta de a le curata. Daca te referi la rolele si sculele de scos aer, pe acestea le curat doar cu acetona. Pot fi curatate si cu Diluant Nitro insa nici un alt solvent nu este la fel de bun ca acetona. Din nou este parerea mea personala. Sper ca raspunsul meu ti-a fost de ajutor, si daca ai si alte intrebari nu ezita sa-mi scrii.

@mihai62834. În primul rand mulțumesc foarte mult pentru comentariu!!! Poți găsi acest fleece la Rompolimer. Se numește voal de fibra C, cu densitate de 30 de g pe m2. Sperând ca răspunsul meu ti-a fost de ajutor, nu uita sa te abonezi la canal în cazul în care nu ai făcut-o deja. Asta ma motivează și mă ajută enorm sa continui. Și dacă ai și alte întrebări, nu ezita sa-mi scrii.

@Ramy Fahoom, Coremat is used instead of foam. It is basically a foam that has small holes that let the resin circulate between the layers of CSM. This results in a very good bonding between the layers, eliminating the risk of delamination. For the future I have a project in which I will use this foam. I want to make a roof cargo carrier for car which can have a high stiffness to be able to mount a solar panel on it and be lightwait. To get these features I will use sandwich fibreglass with coremat foam and CSM.

@@PAFixandCrafts I will wait for that videos, I will always watch all of your channel videos

@namsoemmanson8338. First of all, thank you very much for your comment! I don't know exactly what kind of panel you are referring to, but if you can give me more details, it is possible that I can reproduce this flexible material and do some tests with it. Normally, polyester resin reinforced with glass fiber is quite flexible.

@@PAFixandCrafts can we use polyester resin to make flexible stone veneer?

@namsoemmanson8338. I think I understand what you mean but I'm not really sure. However, you can make a fiberglass mold with the desired stone model in which to pour concrete, plaster or other materials and which you can remove from the mold and put on the wall. It should be a pattern that repeats itself and can be joined at the ends. If you want something very flexible, I recommend you to try silicone molds. They are extremely flexible, non-adherent and can be used up to 300 times.

@Saroj Maharjan. First of all, thank you very much for the comment! There are two aspects that control the gel time of the resin. Ambient temperature and the amount of catalyst used. At 21 degrees Celsius, 1.5 percent catalyst will give you a gel time between 25-30 minutes. And the amount of resin in the bucket slightly affects the gel time. The reaction is exothermic, with heat release. As the resin reacts, it releases heat. The more resin you have in the bucket, the greater the heat released will be. I will make a video in which I explain what percentage of catalyst should be used depending on the temperature and I will also make a gel test with different percentages at a certain temperature. So stay close! If you have other questions, don't hesitate to answer me.

@@PAFixandCrafts thanks for reply … i mixed 0.5-0.8 % cobalt on polyesters resin 2-3 days ago and 0.8-1 % hardener while starting work at around 25-30 deg centigrade …. I am doing 1/4 kg per batch and im having 2-3 mins working time then gets gel … im applying on plywood and its been a week its still sticky … later i mixed 2.5% hardener same problem sticking fiber mat to roller and brush also sticky even after days … don’t know whats wrong me or resin …

@Saroj Maharjan.From my experience, I could say that the amount of accelerator is too high (the amount of cobalt), which causes an accelerated reaction of the resin. Cobalt comes in different concentrations. Concentration of 1%, 2%, 4%, etc. It is extremely important to find out what concentration you used. As an example, if you used cobalt of 4% concentration and the recipe is with cobalt of 1% concentration, that means you should have added 4 times less cobalt. But let's say that the concentration of cobalt is correct, but the quantity is definitely not. The amount of accelerator can never be equal to that of catalyst (" i mixed 0.5-0.8 % cobalt on polyesters resin 2-3 days ago and 0.8-1 % hardener). To give you an example, when I buy an IBC of 1000 KG of non-accelerated polyester resin, I add 4 kg of cobalt with a concentration of 1%. When I work with vinyl ester resin, I add 7.5 kg of cobalt with a concentration of 4%. But this is not a rule. It depends a lot on the type of resin. It can be polyester resin with low styrene emission and in this case it will need more cobalt. The amount and concentration of the accelerator is stipulated in the technical data sheet of the product. Moving on to the second part of the problem, the resin remains sticky because it has too little catalyst. The low amount of catalyst affects the hardness of the laminate, therefore it remains sticky. I do not recommend using the catalyst below 1.2%. And not exceeding more than 2% of it. In this situation, the reaction will be violent with a large release of heat and the pieces will change their color to white or purple, having a tendency to twist due to the tension concentrators that appear in the structure of the laminate. There is pre-accelerated resin on the market. It is a little more expensive, but it saves you from many problems. I only use pre-accelerated resin and buy non-accelerated resin only for special applications.I hope I answered your question as much as possible. And if you have other questions, don't hesitate to write to me!

@@PAFixandCrafts thank you for reply … by the way im using resin in plywood to waterproof

@Erradi .compositer /polyester /epoxy /fibre. First of all, thank you very much for the comment. I saw that you also work in this field or you are passionate about working with resin and fiberglass. I would have really liked to understand what you were saying. I would recommend adding English subtitles. And in terms of sound quality, you should work here too. I had the same problem but I bought a microphone that cost 15 euros and I solved this problem. I also have a video on the channel in which I leave a review about it. Anyway, thank you very much for the comment and I wish you much success. I'll subscribe to your channel so I can follow you.

@iamdeepak311. First of all, thank you very much for your comment!!! The calculation is quite simple. In order to have a maximum degree of reinforcement, a perfect laminate must have a 50-50 factor in its composition. That means 50% resin and 50% fiberglass. This percentage of reinforcement can be achieved, however, by vacuum infusion or RTM / RTM light. For a manual laminate, the ideal ratio is 60-40. That's 60% resin and 40% fiberglass. To which a catalyst percentage of 2% of the resin mass is added. So let's say you want to calculate the amount of resin for 400 grams of fiberglass. You will consequently have 400 grams + 640 grams of resin to which you add 12.8 g of catalyst meaning 2% of the amount of resin. These are ideal values ​​at a constant temperature of 23 degrees. If the temperature is higher, you can juggle the amount of catalyst, but it must not fall below 1.5%. Otherwise the hardness of the laminate will suffer. At low temperatures, you can indulge up to 2.5%. But the thickness of the laminate must be taken into account. The thicker it is and the higher the catalyst concentration, the more heat the reaction will release and the laminate tends to shrink and twist deformed in some places, especially at the corners and edges.

@twins twins. First of all, thank you very much for the comment. I didn't think of doing an impact test. But it's a very good idea. I'm going to think about how to formulate a new episode in which I can test this fiberglass.

@@PAFixandCrafts I was looking for a comparison of how different clothes fit into the matrix. you have exactly what I needed. you proved my guess that the biaxial fits in the same way as the twill. to compare strength, you can make samples of the same thickness and on the same resin, but from different clothes

@@PAFixandCrafts you can test it like this: make a 20x10 cm plate from CSM, a 20x10 cm plate from twill, a 20x10 plate from biaxial, a 20x10 cm plate from non-woven material (honeycombs). Then, when the fiberplastic polymerizes, you need to cut the samples into 2 parts. so that there are plates of 20x5 cm. you will get 2 samples from each fabric. test one specimen with a hammer blow. check material separation. and test the second sample for bending resistance. bending resistance can be tested as follows: take one end of the plate and fix it on the table. attach scales to the second end. then hang the load from the scales and see with what weight the sample will break.

@@PAFixandCrafts like this: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Eea4zsitrGk.html but in this video the guy pulls with his hand, but it's better to hang the load on the scales p.s. I subscribed :)

@twins twins. I can tell you that I have already managed to make the samples. As soon as I have some time, I will film the episode in which I will test them.

@christopher. First of all, thank you very much for your comment! I know and you are right. Several subscribers mentioned this aspect to me. Unfortunately, at the time of filming that video, I didn't have a microphone and the sound quality is really poor. I tried to get the best out of the minimum equipment I had. At the moment I have purchased a microphone and the sound quality is superior. But unfortunately I can't do much for the already published videos.
