| Abstract: | In this paper, the interfacial shear strength of PP/GF composites were measured using single fiber fracture test method, and the effect of transcrystallinity on the interfacial shear strength was studied. It was found that the interfacial shear strength decreases when the isothermal crystallization time increases, and the interfacial shear strength of the sample with the transcrystallinity decreases more than those of samples without the transcrystallinity for long crystallization time. This effect was explained by the poor boundary adhesions of the transcrystalls and the poor welting of the crystals on the fibersurface. |
