Semiaromatic polyamide composite article and processes for its preparation

摘要

A semiaromatic polyamide composite article comprising a first component comprising a fiber-reinforced material comprising a polyamide composition and reinforcing fibers and having a tensile modulus of at least about 16 GPa as measured by ISO method 527-2:1993 at a rate of 5 mm/min on test specimens having a thickness of 4 mm, a second component comprising a polyamide composition, and an optional tie layer therebetween. The polyamide composition of first component and/or the second component is a semiaromatic polyamide compositions. The second component is prepared by injection molding and/or injection-compression molding the semiaromatic polyamide composition onto the first component.
