Abstract:

Thermoset composites were made from prepregs of 3 mm long, high modulus and high strength carbon fiber aligned by the ERDE filtration process. Some mechanical and physical properties of these composites have been measured and compared with values obtained for continuous carbon fiber composites made from the same batches of fiber. In most cases the properties of discontinuous fiber composites made by this process were similar to those obtained with continuous fiber except for flexural and tensile strength which exhibited a reduction of 30 to 40 per cent when using short fibers. The properties of planar pseudo-isotropic composites made from discontinuous fiber pseudo-random mats were shown to be markedly superior to those for random carbon fiber composites. Author-PL
