Interlaminar Shear

A novel epoxy/SiO2 hybrid sizing for carbon fiber surface was prepared through sol-gel technique, the structure of the sizing were analyzed, and the effects of the sizing on mechanical properties of carbon fiber composites were also investigated. The analyses by FT-IR and SEM indicated that epoxy/SiO2 hybrid sizing was prepared successfully, SiO2 particles dispersed in the hybrid sizing film homogeneously with nanoscale. The analyses on interlaminar shear strength (ILSS) and impact properties of composites showed that the epoxy/nano-SiO2 hybrid sizing increased ILSS and improved impact properties obviously at the same time.

Shear Compliance

A special test setup was designed and used in compression shear test of unidirectional carbon fiber composites to study the effect of short fiber interleaves (SFIs) on the interlaminar shear behavior. The comparative tests for two kinds of double-notched compression specimens, with and without SFIs, were carried out to determine the interlaminar shear strength and modulus (ILSS and ILSM) and to examine the failure characteristics. To determine ILSM of the specimens with SFIs an inversion analysis method was proposed based on comparing compression displacement of specimens with and without SFIs. The experimental results show that SFIs makes ILSS decreasing due to lower interface strength, and the complex damage process of SFIs leads to a considerable increase of interlaminar shear compliance.
