The compressive yield strength of glass microsphere – epoxy composites was evaluated as a function of the interface strength. The behaviour of composites with microspheres without any surface treatment was compared with that of composites fabricated with silane-treated and silicone oil-treated microspheres. Varying the hardener-to-epoxy ratio of the matrix also modified the interface. The results were compared with those derived from theoretical models, and it was shown that for hollow glass microsphere composites the effect of surface treatment can be quantitatively described using extant models. Changes in the reinforcing effect and stress concentration factor caused by the presence of the microspheres are discussed, and the experimental results explained.

The Impact

The present work aimed to analyze the roll of carbon nano tubes and graphene nano fillers on the mechanical and thermal characteristics of hollow glass microsphere reinforced epoxy composites. Composites with varying content of hollow glass microballoons (2, 4, 6, 8, and 10 wt %) reinforced in epoxy matrix were fabricated. Additionally, two more types of composites, one with graphene nano fillers and the other with carbon nano tube at a constant 0.5 wt %, were fabricated with varying weight percentages of hollow glass microballoons (2, 4, 6, 8, and 10%). The composites were fabricated using an open mold casting process. Composites were tested for thermal and mechanical properties. The tensile and flexural moduli were found to rise as the HGM concentration increased. Graphene-filled HGM/epoxy composites revealed the highest modulus compared with HGM/epoxy and HGM/CNT/epoxy composites. The impact strength of all composite types decreased as the HGM content increased. Neat epoxy specimens revealed low response as compared with all the composites tested. Further, the thermal conductivity of HGM/epoxy composites was lower as compared with other compositions and neat epoxy. Scanning electron microscopy was used to analyze the surface morphological behavior of the composites subjected to flexural test. It was found that HGM/G/E composites with 10% of HGM and 0.5% of graphene by weight in epoxy matrix were the optimum.
