Experimental investigation on mechanical behavior of synthetic based bidirectional reinforced hybrid epoxy laminates

摘要

The design engineers are vigilant about weight reduction without compromising on the structural strength. The composite is a lightweight material that has good structural properties, and it is widely used as it can be tailored based on the requirements. Fabric-reinforced polymer composites have a wide applicationin engineering because of its high specific strength. The fabric serves as reinforcement, and it may be synthetic or natural. Synthetic fibers are not only strong but also lightweight. In the present work, fabrication and experimental investigation on synthetic fiber-based polymer composites are carried out. Initially, bidirectional carbon, Kevlar, and glass laminates are fabricated using hand lay-up and vacuum bagging methods. Then, hybrid laminate made up of carbon-Kevlar and carbon-glass laminates are fabricated, and experimental investigationis conducted to study their mechanical behavior. The comparative studies on the laminates are carried out and theobtained results are quite interesting.
