| Abstract: | Interface strength and the character of fracture of bonds formed in the reaction of thermosetting binders with aramid (SVM, Armos, VMN-88) and polybenzothiazole (PBT) fibres are determined by the chemical affinity of adhesive and fibre and the ability of the binder to diffuse into the fibre. The strength of unidirectional composites based on these systems is not a function of the interface strength in many cases; the fibres themselves are the  weak link in the composite. |
