Processing of thermoplastic matrix-carbon fiber composites

Thesis/Dissertation ·
OSTI ID:7049239
The effect of processing on the adhesion of AS-4 graphite fibers to polycarbonate, polyetherimide and polyester is examined. The adhesion is quantified using single fiber composite specimens. The specimens are carefully fabricated with different levels of applied pressure and cooling rate. It is found experimentally that both pressure and cooling rate can affect adhesion of the graphite fibers to the thermoplastic matrix materials. In general, adhesion is improved with higher pressures and slower cooling rates. Residual stress in a model composite is calculated and compared to the differences in adhesion with different processing histories. The results of the theory agree qualitatively with the experimental results.
