Method for molding composite articles

摘要

There is disclosed a trapped polymer method for molding composite articles at temperatures of at least 535 DEG C., comprising heating to a temperature of at least 535 DEG C. a mold containing a master tool, a pre-preg and a trapped polymer comprising a depolymerization-resistant silicone crumb rubber which is resistant to depolymerization of the polymer backbone at a temperature of at least 535 DEG C. to form and cure said pre-preg into the desired composite member.
