In this work, the effect of catalyst on mechanical properties of carbon fibers-reinforced epoxy matrix composites cured by cationic latent thermal catalysts, i.e., N-benzylpyrazinium hexafluoroantimonate (BPH) was studied. As a result, the conversion of neat epoxy matrix cured by BPH was higher than that of one cured by diaminodiphenyl methane (DDM). The ILSS, KIC, GIC, and impact strength of the composites cured by BPH were also superior to those of the composites cured by DDM. This was probably due to the consequence of the effect of substituted benzene group of BPH catalyst, resulting in increasing the cross-link density and structural stability of the composites studied. |
