To my understanding, pre-preg is fibres (typically cloth) that has been
impregnated with matrix (resin, typically epoxy), but then put to
freezer before the matrix hardens. So when using pre-preg, you do not
need to mix the resin and apply it to the cloth, but you just simply
take the roll of the pre-preg, cut the desired parts, ally them to the
mold and autoclave the whole thing until the resin has cured. This
avoids the difficult part of mixing the resin and applying the proper
amount of it to get the right fiber-to-resin ratio in the laminate.
