Abstract

The utilization of carbon and glass fiber composites is very extensive in the fields of aviation and automobiles. The strength to weight fraction of these composites is immense. Even though, the modern applications require a lot of improvement in strength. The addition of Nano fillers had brought about significant changes in mechanical properties of the composites. The present work aims at finding out the effects on mechanical properties of composites due to the addition of titanium oxide 10% + silicon dioxide 10% hybrid filler. Hand layup process is used for the fabrication of tensile and flexural test specimens which are prepared as per the ASTM standards. The tensile test specimen is D-638 type-iv and the flexural specimen is D-790. Epoxy is used as resin and forms the matrix whereas the carbon and glass fibers act as reinforcement. The comparison is made between the specimens with and without hybrid filler. Two specimens of each type are prepared to have repeatability. The tensile and flexural tests are carried on universal testing machine (UTE-10) and results were obtained. The results showed a significant improvement in tensile and flexural strengths of carbon composites and only flexural strength in glass fibers with hybrid filler.
