✦ Synopsis
Aromatic polyamideimide (PAI) films were reinforced with aromatic polyamide fiber (DuPont, Kevlar 49) as unidirectional composite (type I), bidirectional laminate composite (type 11), and bidirectional cloth composite (type 111). The elastic and tensile load-elongation properties of composite films at ambient temperature were investigated with respect to fiber orientation. The properties of the type I composite film are more anisotropic than those of other composite films. But, for the type I composite film, the most significant effect of the reinforcement fiber is observed at the fiber direction. With bidirectional reinforcement (types I1 and 111) the anisotropy of the composite is reduced, but the strengths at the fiber directions are depressed markedly by the existence of the fibers of the other orientations.
