| 520 | 3 | _aThe fracture toughness of unidirectional continuous carbon fibre composites (CFRP)containing modified epoxy resin matrices has been studied in transverse impact fracture and Mode I delamination fracture tests. It is shown that the transverse impact fracture toughness values for composites with modified matrices are generally similar to those without modifiers in the temperature range 0°C to 80°C. At sub-zero temperatures the composites containing rigid A1203 powders in the matrix have much larger toughness values than the control. Potential energy release rates and stress intensity factors in Mode I delamination were measured to construct the crack growth resistance curve (R curve)by including the residual displacement effect. The R curves for rubber modified matrix composites (both with and without AI20 3 fibres or powders)are much superior to that of the control. However, addition of these rigid fillers without the presence of rubber did not significantly alter the R curve behaviour. Toughening mechanisms are discussed in relation to the plasticising effect of the rubber and the embrittling effect of the rigid fillers on the non-linear deformation of the modified matrices. The present results on carbon fibre composites with a low fibre volume fraction (Vf = 0.20)follow reasonably well the already established relationship between resin toughness and the composite delamination fracture toughness for similar composites with V~ over 0.55. | |
