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.
