Modified Epoxy

The epoxy resins were toughened with reactive core-shell nanoparticles(CSNPs) with butyl acrylate (BA) as the core and methyl methacrylate (MMA) copolymerizing with glycidyl methacrylate (GMA) as the shell. The chemical structure of the CSNPs was characterized by FT-IR. The morphology of toughened epoxy networks were analyzed by SEM and TEM, and their adhesion properties were also detected. The results show that mixing methods and CSNP concentration have great influence on the morphology and adhesion properties of the toughened epoxy networks. CSNPs are uniformly dispersed in the epoxy resins by the grinding method. The modified epoxy networks obtained from the modified epoxy networks prepared by the grinding method(MEPN2) with 10 wt% CSNPs show the best adhesion properties, and the increase in maximum peel strength, 25°C sheer strength and 150°C sheer strength of the modified epoxy networks is 401.3% , 46.9% and 27.6% respectively over the unmodified epoxy networks due to the small-scale coagulations of CSNPs.

Deformation And Fracture

Abstract Close cell structured foams are made by incorporation of cenospheres in polymeric materials. Low moisture absorption characteristics and considerably higher compressive strength of these materials compared to open cell structured foams make them suitable for use as core materials in sandwich structured materials. Incorporation of cenospheres in the epoxy resins enhances their impact strength and damage tolerance, especially if these materials are used in sandwich configurations. Present study analyzes and compares the effect of incorporation of cenospheres like flyash and glass microballoons in the epoxy resins on the deformation and fracture behavior of the material. Approach based on determination of local stress intensity factors is used to obtain estimate of the stresses in the material.
