Hi everyone,
OK ive been doing composites for 7-8 years now and i have a small company making automotive and motorsport products. When we make moulds we normally cut patterns from cnc/tooling block but i have a few products that i need to make moulds directly of the pattern from in prepreg. Ive done wetlay glass/ carbon which is fine but as the pattern and flanges will be under vacuum (envelope bagging) the flanges need to be very strong and not come away from the pattern when under pressure/heat.
What im struggling with is what is the best thing to stick the flanges (and what material to use for prepreg flanges) to the pattern and as the patterns can be quite complex shapes, the flanges may only be edge-edge bonded in some areas with very minimal bonding footprint…
Any help would be much appreciated here guys as its one thing im struggling to solve!
thanks in advance and i look to hear from you soon
