Effect of Temperature on Dynamic Characteristics of Carbon - Kevlar Fiber Reinforced Composites

Abstract

For the purpose of this investigation, carbon and Kevlar fiber-reinforced plastics were subjected to dynamic testing. Carbon-Kevlar fibers are included into the LY 556 resin and AR 951 hardener. Fiber makes for 40% of the study's total weight. The carbon and Kevlar composites were created by hand lay-up. The orientation considered in this research is 0/0 and 0/90 for both carbon and Kevlar composites. Advanced characterizations such as TMA and DMA has been integrated in this research. By using DMA (Dynamic Mechanical Analyzer) and the thermomechanical Analyzer (TMA), the dynamic properties were acquired. ASTM E756 was used to conduct the tests. Composite heating at room temperature to 1200 C was the temperature variable under investigation. The studies were conducted on TMA and DMA with a force of 0.002N, respectively. DMA uses a three-point bending loading design for its samples. Temperature affects the dimensions, storage modulus, loss modulus, and tan delta.
