Carbon fiber-reinforced polymer composites have been widely used in the aerospace industry. However, they are extremely sensitive to crack initiation, propagation and interlaminar delamination which severely reduce their service life. This paper demonstrated that the Mode-I interlaminar fracture toughness could be significantly improved in carbon fiber/bismaleimide composites using a microwave curing process. An increase of about 53.5% in critical load and an increase of approximately 133.5% and 61.2% in fracture toughness and fracture resistance have been achieved, respectively. The microwave manufacturing cycle for composites was cut to 44% of the thermal processing cycle. Dynamic mechanical thermal analysis was performed to investigate the enhanced interfacial strength in microwave-cured composites. The improvement in fracture toughness was attributed to a better interfacial adhesion between resin and fiber, which was investigated by the observation of fracture surfaces with optical microscopes.

The nanosheet boehmite (AlOOH) was synthesized and used as reinforcing agent to toughen carbon fiber-reinforced polymers. The purity, morphology, size and composition of the AlOOH nanosheets were investigated by the methods of XRD, SEM, TEM and FTIR, respectively. Interlaminar fracture toughness for mode II deformation was investigated for carbon fiber-reinforced polymers toughened by AlOOH nanosheets varying the contents at room temperature (RT, 293k) and at low temperature (LT, 77k). The fracture surfaces were examined by SEM to correlate with the interlaminar fracture properties. The results indicated that the synthesized AlOOH nanosheets were pure crystalline and of high purity. By TEM, the thickness of the lamellar AlOOH sample is about 22 nm. The end-notched flexure test results show that interlaminar fracture toughness of unidirectional carbon fiber-reinforced polymer with the same content AlOOH nanosheets (0, 1, 1.5, 2, 2.5, 3 wt.%) at LT is higher than that at RT. The interlaminar fracture toughness reaches the highest when the AlOOH nanosheets content equals 2% at RT. But at LT, the highest interlaminar fracture toughness appeared in the carbon fiber-reinforced polymers without AlOOH nanosheets.
