<p>A shaped reinforced thermoplastic composite, such as composite laminate (10), comprises a thermoplastic matrix polymer (22) and a plurality of long fibers (20) of a liquid crystal polymer (LCP) which are formed in situ in the matrix polymer. This composite is formed by forming a prepreg as a plurality of individual sheets or layers (12, 14, 16, 18) each of which comprises long, essentially unidirectionally oriented fibers (20) of said LCP in a thermoplastic polymer matrix (22). A lay-up is formed by cutting each individual sheet or layer into pieces so that the direction of fiber orientation in each such piece is either parallel to one pair of edges or at angles of 45 degrees to all of the edges. The lay-up is shaped under heat and pressure to form the composite.</p> |
