Abstract
A vacuum bag autoclave type procedure for curing layers of phenolic resin pregnated fibrous material to form a composite structural part. A straight up heat rise cure cycle is employed in conjunction with a layup and bagging procedure that ensures a relatively free bleed of excess resin during cure and a high-capacity vacuum system for removal of volatiles generated during cure. This method of fabrication releases the majority of volatiles prior to gelation and produces a part having a pore structure that provides an escape path for gases generated during cure and postcure to prevent delamination.

pregnated fibrous material to form a composite structural part. A straight up

Claims
What is claimed is:
1. A vacuum bag autoclave process for manufacturing thick laminated structural
parts, said-parts having 60 or more layers making said part 0.5 inch or greater
in thickness, said parts being formed entirely from layers of phenolic resin
impregnated fibrous material, said process allowing the formation of parts of
up to 100 layers in thickness which are capable of withstanding a post cure
temperature of 450.degree. F. without delamination, said process allowing the
formation of said structural parts from phenolic resin impregnated fibrous
material having a wide range of resin advancement, which process comprises:
(a) stacking layers of said resin impregnated fibrous material to a desired
thickness on a layup surface providing the contour for the part;
(b) curing said stacked layers into a unitary structure by heating said stacked
layers at 1.degree. F. per minute or greater until the maximum cure temperature
for a prescribed period while simultaneous...
