Abstract
Described herein are thermoplastic composites including a polymer matrix, having a at least one semi-crystalline polyphthalamide ('PPA') polymer, and at least one continuous reinforcing fiber. It was surprisingly discovered that incorporation of semi-crystalline PPA polymers, having a selected melt profile, into the polymer matrix provided for crack-free thermoplastic composites. Based at least in part on the semi-crystalline structure of PPA polymers, the thermoplastic composite can have improved tensile strength, chemical resistance and thermal stability, relative to composites incorporating an amorphous PPA polymer. The composites can be formed using melt impregnation techniques, well known in the art. The composites can be desirably used in a wide range of application settings including, but not limited to automotive, aerospace, automotive and oil and gas and mobile electronic device applications.
