Toughness and Fracture Mechanism of Carbon Fiber Reinforced Epoxy Composites
文献摘要:
The fracture toughness of carbon fiber reinforced epoxy composite (CFRP) was investigated through mode I and mode Ⅱ shaped fracture system in this paper. A novel polyimide with trifluoromethyl groups and grafted nanosilica were used to modify epoxy resin. Effect of modified resin and unmodified resin on fracture toughness of CFRP was compared and discussed. Lay-up angles and thicknesses effects on fracture toughness of composites were also investigated. The fracture toughness of CFRP was obtained through double cantilever beam(DCB) and end notched flexure(ENF) tests. The results showed that the composites prepared by modified resin exhibited high fracture toughness compared with unmodified composites. The fracture toughness value of mode I increased from 1.83 kJ/m2 to 4.55 kJ/m2. The fracture toughness value of mode Ⅱ increased from 2.30 kJ/m2 to 6.47 kJ/m2.
