Abstract

Poly(p-phenylene benzobisthiazole) (PBT) fibers are receiving considerable attention because of their excellent thermal, chemical, and mechanical properties. However, a major constraint of using PBT fibers as structural material in airplane design is their low compressive strength (about 50 ksi). This problem is being investigated by the Air Force Wright Aeronautical Laboratories and their various contractors. In this paper, we discuss an approach to increase the compressive strength of rigid-rod PBT polymer fiber by incorporating a thermally reactive crosslinking moiety, fluorene (FL), into PBT. An advantage of incorporating fluorene is it may crosslink by an addition reaction and, therefore, would not generate volatiles as in the crosslinking of methyl pendant PBT copolymers presented in our companion paper. The synthesis of PBT/FL copolymer has been discussed in Part 1.
