Abstract
A thermoplastic vulcanizate comprising of a dynamically-cured rubber; and a thermoplastic phase, where the thermoplastic phase includes fiber and the reaction product of a methylene donor and a methylene acceptor. The thermoplastic phase could include a functionalized thermoplastic resin.
Claims12
A method of forming a fiber-reinforced thermoplastic vulcanizate, the method comprising:
- dynamically curing a rubber while the rubber is undergoing mixing with a thermoplastic resin to form a thermoplastic vulcanizate feedstock;
- and
- introducing fiber, a methylene donor, a methylene acceptor, and optionally a functionalized thermoplastic resin, with the thermoplastic vulcanizate feedstock to form the fiber-reinforced thermoplastic vulcanizate;
- wherein nylon is not added in either the dynamically curing step or the introducing step.
