The PEI Localization Effect on the Impact Properties of PEI toughened Carbon / Epoxy Composites
Jang, Jyong Sik,Shim, Jyong Sup,Shin, Seung Han 한국공업화학회 1999 Journal of Industrial and Engineering Chemistry Vol.5 No.3
The impact properties of carbon/epoxy composites as a function of PEI content were investigated by means of a driven dart impact test. The impact properties of PEI toughened carbon/epoxy composites were enhanced with increasing the PEI content. This was mainly due to the suppression of matrix cracking by PEI particles. Although the same amount of PEI was used, the mechanical properties of carbon/epoxy composites were varied by the PEI localization. When the PEI toughened layer was located at the opposite side of impact point, the total impact energy of carbon/epoxy composites showed maximum value due to the easy deformation of PEI toughened layer. In addition, the flexural strengths of carbon/epoxy composites also depended on the PEI localization effect.
