| Abstract: | In order to improve the production efficiency and molding quality of the plant fiber reinforced composites prepared by the vacuum assisted resin infusion process,styrene was used as a diluent,and unsaturated polyester resin(UP)of different viscosities and ramie fabric were used to prepare ramie fabric reinforced UP composites.Based on Darcy’s law,the influence of UP viscosity on the permeability of ramie reinforcement was studied,and the molding quality of composite was analyzed based on the fiber volume fraction,mechanical properties and internal defects of composite.The results show that as the UP viscosity decreases,the permeability of the reinforcement increases almost exponentially,and the fiber expansion effect gradually increases,while the mechanical properties first increase and then decrease,which is related to the curing mechanism of the styrene crosslinking monomer.The overall performance of composite prepared by 360 mPa·s UP is the best,and its permeability,tensile strength,tensile modulus of elasticity,flexural strength,flexural modulus of elasticity and shear strength are increased by 22.22%,20.80%,12.05%,5.44%,7.58%and 8.27%respectively compared with composite prepared by 440 mPa·s UP.The reduction of UP viscosity improves the hysteresis of UP flow inside the yarn,so the internal defects of UP composites are gradually reduced. |
