Abstract

The tensile mechanical behavior of a short carbon fiber filled liquid crystalline polymer (LCP) composite, Vectra A230, was examined under static extension and dynamic loading at three temperatures. Dynamic tension was applied using a pendulum-type tensile spilt Hopkinson bar device. Specimens fabricated according to both the mould flow and transverse directions were tested. The stress-strain curves at various strain rates and temperatures were determined and found to be sensitive to strain rate as well as temperature for both types of specimens. With reference to the properties of pure LCP, mechanical anisotropy and fiber reinforcement effects were characterized and are discussed. Failed specimens were observed suing an optical microscope. Deformation and failure mechanisms in the microstructure of the LCP composite were studied to understand the effects of strain rate and temperature on material strength and failure strain.
