ABSTRACT:
A fabric is resin-impregnated by placing it between a liquid resin surface and an evacuated space. The fabric can be laid on top of or passed continuously over a liquid resin surface, the resin being heated to a temperature at which it flows readily. A pre-preg produced according to the method can be laminated with other pre-preg or fabric layers into board, but several fabric layers can be impregnated together to form a thick pre-preg.
