Mechanical Characterization of Laminated Carbon Fiber Reinforced Polymer

Experimental method was employed to investigate mechanical characterization of carbon fiber reinforcement polymer (CFRP) composite beams at different temperatures. The experimental research is mainly based on the vibration response measurement by using technique electronic speckle pattern interferometry (ESPI), which can provide visualization vibrating information represented as fringe patterns. first ten order out-of-plane mode shapes and natural frequencies temperatures are obtained ESPI method. Based Euler-Bernoulli beam theory, flexural moduli CFRP laminate determined. changes in modes 0 degree off-axis has been investigated this paper.
