Abstract

See full text

A process for the production of a polymeric article comprises: (a) forming a ply having successive layers, namely, (i) a first layer made up of strands of an oriented polymer material; (ii) a second layer of a polymeric material; (iii) a third layer made up of strands of an oriented polymeric material, wherein the second layer has a lower peak melting temperature that of the first and third layers; (b) subjecting the ply to conditions of time, temperature, and pressure sufficient to melt a proportion of the fits layer, to melt the second layer entirely, and to melt a proportion of the third layer, and to compact the ply; and (c) cooling the compacted ply. The resultant articles have good mechanical properties yet may be made at a lower compaction temperature than articles not employing the second layer, leading to a more controllable manufacturing process.
