The effect of composition and injection rate on the structure of short carbon fiber reinforced polyamide 6 (PA6) composites is discussed. Fiber length and orientation are measured and correlations between the structure and impact behavior are established. Average fiber length decreases with increasing fiber content and processing rate. The structure is contradictory to those of short glass fiber reinforced composites. Fibers orient randomly relative to the mold fill direction in the skin layer. Although instrumented impact testing indicate brittle failure at all combinations, the strain energy release rate is not determined by the usual technique.
