ABSTRACT:
A composite article fabricated by a process comprising (1) bringing into intimate contact two copolyetherester elastomers having melting points differing by at least 20.degree. C., the copolyetherester elastomer (A) of higher melting point being in the form of a plurality of oriented strands, tapes or films and (2) heating the resulting assembly to a temperature between the melting point of the two elastomers to cause fusion of copolyetherester elastomer (B) of lower melting point while maintaining the orientation of copolyetherester elastomer (A).
