The effect of hybridization on the mechanical performance of carbon/aramid epoxy fabric composite

The effects of hybridization with glass layers on the mechanical and vibration properties of carbon/aramid hybrid composites were investigated. In order to determine the effect of the hybridization on the mechanical properties of carbon/aramid, pure carbon/aramid epoxy and pure glass/epoxy composite laminates were compared with hybrid composites. The results showed that the replacing of Sglass fibers with carbon/aramid fibers in the composite laminate could give enhancements in the flexural properties while the hybridization showed negative effect on tensile characteristics. Moreover, the results of flexural test were found that when putting S-glass fibers on the compressive side of composite laminates were realized important enhancements for flexural properties in contrast with the putting carbon-aramid fibers on tensile side. Utilizing the half power band-width technique, the damping characteristics were deduced from the vibration response envelope curve. Loss modulus, storage modulus and damping ratio of the structures were also calculated. It was observed that the result of hybrid configuration could provide improvements in the vibration characteristics.
