[EXPLORE] Core Experiments 1: THICKNESS 

This video is the start of a new series exploring composite core materials and their various properties. Today we are focusing on how thickness affects the stiffness of composite layups. The experiment design is not the best and the results are a bit haphazard but there are still some rather good lessons to take out of the whole ordeal.
Check out my website, if you have any projects you want help on hit me up and we'll see what we can do. www.chapmaneng.com
The infusion connector is available from my website or directly at: www.ebay.com.a...
For general material properties "performance composites" is a good source: www.performance...
And this was a good reference for the properties of PU foam: www.pg.gda.pl/m...
As always when doing this kind of work, make sure that you use appropriate PPE, store the chemicals properly (both in an absolute sense for your safety, as well as in accordance with your local laws and regulations) and be mindful of dust generation and removal.
