Abstract

Polymer composites based on carbon fibers are used in a large number of applications generaly as bearing structural parts in aerospace, automotive and other industries. In many composite parts, unidirectional (UD) tapes are used to create structures in aircraft, vehicles in addition to sporting and consumer markets. UD tapes are lightweight and exceptionally durable and they are the basic building blocks for a production of composite structural laminates. The aim of this work is to determine the influence of angles and technologies for curing on the structural and mechanical properties of UD carbon fiber/epoxy laminate, manufactured with Automated Tape Layup (ATL) and Automated Fiber Placement (AFP) technologies. The tensile strength and modulus at different laminates with different technologies were calculated since ASTM D3039. The failure analysis of the samples was investigated by scanning electron microscopy (SEM). The results have shown that the mechanical properties depend on technologies for curing. The results of the present study indicate that angles have a significant effect on composite failure mode. It is also found that the strength of UD composites both increased at samples curing with press technology.
