Abstract

VRAM (vacuum resin absorbable molding) process was used to prepare the epoxy resin matrix hybrid composites with ramie fiber cloth and glass fiber cloth.The storage modulus, the loss factor and the mechanical property of the composites were tested.Vibration characteristics were estimated through the resonance frequencies and free vibration decaying curve via the single cantilever beam vibration test.Meanwhile, the damping factors were obtained by calculation.Finally, the finite element simulation software was used to do some simulation analysis on the resonance frequencies and free vibration decaying experiments.The results show that the contradiction between the damping properties and the mechanical properties can be balanced by the hybrid plies of the ramie fiber cloth and the glass fiber cloth.Therefore it can realize the controllable regulation of the damping properties and the mechanical properties and give full play to the remarkable designing advantages of composites.Among them, loss factor and tensile strength of the composites with RGR lay-up are 1.4 times more than the pure glass fiber cloth composite, and 3 times more than the pure ramie fiber cloth composite, respectively.The finite element simulation curves of free vibration are basically consistent with the experiment results.It shows that virtual vibration test of laminated composite can be realized by simulation software, so as to provide convenience for material performance prediction and design.
