Abstract
A melt consolidated, multiaxially oriented liquid crystal polymer ("LCP") sheet or other article formed from LCP particles. One embodiment includes a multi-component LCP sheet in which particles of a higher melting LCP are imbedded in a matrix of a lower melting LCP. These LCP components are formed into sheet at a temperature between the melting point of the lower melting matrix LCP and the higher melting reinforcing LCP, so that the imbedded LCP particles may maintain their shape, orientation, and mechanical characteristics while the matrix LCP component flows around the particles and forms a solid sheet. In another embodiment, LCP particles are melt consolidated to form a single article in which a significant amount of LCP orientation is retained. A sheet of this invention may be formed by a variety of processes, and may be made from recycled scrap LCP.
