Carbon Fibre Reinforced Plastics

The low-temperature fracture properties of a carbon fibre reinforced epoxy composite have been investigated by conducting a series of mode I, mode II, interlaminar shear strength (ILSS) and drop-weight impact tests at temperatures between — 194 and 23 °C. Initial tests on the pure epoxy indicated that the mode I fracture toughness of the pure resin increased steadily with reducing temperature. Similar trends were observed in the ILSS and mode II data where increases of up to 100 per cent were observed over the range of temperatures examined. No appreciable temperature dependence was observed, however, in either the mode 1 fracture data or the overall impact damage area.

Delamination Resistance

Through-thickness stitching is one of the most effective techniques to improve the delamination resistance of composite laminates. The effects of two different stitching patterns on the mode-I interlaminar fracture toughness of unidirectional carbon fiber reinforced plastics (CFRP) are examined experimentally in the present paper by using the double cantilever beam (DCB) test method. It is found that the zigzag stitching pattern results in a better toughening effect than the straight line pattern, and that the stitching density also has a considerable influence on the mode-I fracture toughness.
