What is the definition of prepreg hull
Prepreg is the material that is used to lay-up the hull and requires allot of prep work to make a final product. Prepreg itself is where the cloth being used has already been
pre-impregnated with a specific amount of resin. The cloth varies. It can be glass, kevlar carbon ect. The reason that prepreg is a good method is b/c it keeps the cloth to resin ratio
low or
optimum. A cloth is rated to particular value and in most cases when the resin content surpasses that value the part does not get any stronger, just heavier. The cloth is laid in the mold, vacume bagged and autoclaved (bakes in oven) to activate the resin. For the ultimate in lightweight a core material is used. What that does is substitute a solid glass core with a honeycomb material. Same principal as prepreg, less material the lighter the weight. Making a light part is all about the resin content and prepreg is a precise (but expensive) way of controlling the resin/cloth ratio.
The ride plate is not prepreg. Just a composite plate with a layer of carbon for asthetic purposes.
here is a better illustration of what prepreg is:
