Process for Preparing a Self-Reinforced Thermoplastic Composite Laminate
Composite laminates are prepared from thin sheets of thermotropic liquid crystal polymer blends. A preferred blend contains 2 thermotropic liquid crystal polymers, i.e., a first liquid crystal polymer in LCP-1, and a second liquid crystal polymer (LCP-2), the second liquid crystal polymer having a higher melting point than the first. The second liquid crystal polymer is molecularly oriented and is preferably at least partially in the form of microscopic fibers in a matrix of the first liquid crystal polymer. The two liquid crystal polymers are phase separated in the solid phase and have overlapping melt processing temperatures.
