The morphology of two new high performance polymer fibres, rigid-rod poly( p -phenylene benzobisoxazole) (PBO) and stiff-chain poly(2,5(6)-benzoxazole) (ABPBO), has been examined by wide angle X-ray scattering and scanning and transmission electron m

The addition of lithium chloride to solutions of poly(5,5′-bibenzimidazole-2,2′-diyl-1,3-phenylene) (PBI) and N,N-dimethylacetamide (DMAC) resulted in the elongation of the PBI molecule in solution. This elongation is due to the association of li

Experimental studies of fiber wet-spinning and solution processing of films of molecular composites are presented. The rigid rod polymer was poly (p-phenylenebenzobisthiazole) (PPBT) and the flexible polymers were poly (2,5(6′)-benzimidazole) (ABPB

The entanglement molecular weight necessary for integrity of processed fiber and film for rigid rod molecular composites is discussed. The case presented is one where the matrix flexible coil polymer has a marginal molecular weight for entanglement.

The structure and morphology of homopolymers and blends of rigid-rod poly(p-phenylene benzobisthiazole) (PBT) and semiflexible coil poly[2,5(6)benzimidazole] (ABPBI) were examined by wide-angle x-ray diffraction and scanning and transmission electron

Axial compressive behavior of carbon and high modulus organic fibers (such as Kevlar and PBT) has been discussed. The compressive strength of carbon fibers is found to in crease with a decrease in density, over a limited density range. Possible model
