Abstract

To enhance the viscosity and thermal resistance of DGEBA epoxy resin, a phenol novolac-type epoxy resin was added to a hot melt-type epoxy prepreg. The mixtures of DGEBA solid and liquid epoxy resin, and phenol novolac epoxy resin were prepared with different mixing ratios. The effect of the mixing ratio on the curing behavior, thermal stability and viscosity of the blended epoxy resin was investigated. The curing behavior did not vary significantly with the mixing ratio. The activation energy increased as the content of phenol novolac-type epoxy resin was increased up to 40 wt%. The thermal resistance and viscosity of the mixed epoxy resin increased significantly when the phenol novolac-type epoxy resin and solid epoxy resin occupied more than 20 wt%.
