Claim Text:
1. A polymeric article having a non-planar shape comprising a compacted ply including at least three layers that is adapted to be subjected to conditions of time, temperature and a single compaction temperature to melt at least 1% but no more than 30% by volume of first and third layers and substantially all of a second layer wherein the compacted ply is further configured to be subjected to a compaction pressure to form a non-planar article, wherein a thickness of the first and third layers individually exceed a thickness of the second layer, and wherein the first and third layers of ply comprise the same polymer and the second layer comprises a polymer with the same chemical composition and grade of polymers as the first and third layers with a lower degree of molecular orientation and lower peak melting temperature than that of the first and third layers.
