great vid but should you not alternate the fibre direction ?

@epoxycraftnewsletter 7 лет назад

Thank you for your very valid comment. However on a small vessel such as this we believe it is appropriate to have the biaxial fibres running at ±45° to the waterline to address the loading to the hull structure. On a larger more complex structure it may be fitting to have the fibres orientated to address all 4 axes. On such larger, complex structures it is recommended for an engineer to specify the exact fibre type and orientation in order to maintain the structural loading characteristics of the hull.

What is the cure time for this epoxy?

Hi Ralph, WEST SYSTEM 105 Epoxy has 4 hardeners available. Offering different cure speeds. Details can be found here wessexresins.co.uk/west-system/find-the-right-product/hardener-filler-and-additive-selection-guides/ In this video, we used WEST SYSTEM 205 Fast Hardener which provides a pot life of 10-15min, a working time in thin film of 60-70min and a cure to solid state in thin film of 5-7 hours.
