ABSTRACT:
A composite construction incorporating one or more non-woven layers at least partially formed from heat fused monoaxially drawn tape fiber elements of discrete length. The non-woven layers are provided with a mat structure covering across at least one surface. The mat structure covering is formed at least partially from interwoven heat fused, monoaxially drawn tape fiber elements of elongate length. The tape fiber elements in the woven and non-woven layers incorporate a base layer of a strain oriented polymer and at least one covering layer of a heat fusible polymer. The covering layer of the tape fiber elements is characterized by a softening point below that of the base layer to permit bonding fusion upon application of heat.
