Abstract

Software-based mold flow analysis is often performed to confirm optimized resin pipe arrangements. In this study, the GeoDict software and reverse scanning were employed to develop a method for performing rapid porosity and permeability estimation. A comparison of the results from one-dimensional resin flow and Easyperm tests revealed a 10% variation in the porosity and permeability parameters obtained through the proposed rapid estimation method. In addition, the obtained parameters were substituted into a Moldex3D model to simulate the resin flow on the personal watercraft hull during vacuum-assisted resin transfer molding (VARTM). A comparison of simulation results and hull infusion results revealed that the integration of the proposed rapid estimation method with Moldex3D allowed for the accurate simulation of the resin flow in large fiber-reinforced-plastic (FRP) products (variation <8%). The proposed method can be applied to large wind turbine FRP parts and large FRP yacht components to increase process planning efficiency and product stability.

通过反扫描获取真空辅助树脂传递成型关键参数在大型纤维增强塑料制品制造中的应用

基于软件的模流分析通常用于确认优化的树脂管布置。在本研究中，采用GeoDict软件和反向扫描开发了一种快速估算孔隙度和渗透率的方法。通过对一维树脂流动和Easyperm测试结果的比较发现，通过提出的快速估计方法获得的孔隙度和渗透率参数变化幅度为10%。此外，将得到的参数代入Moldex3D模型，模拟了真空辅助树脂传递成型(VARTM)过程中树脂在个人船体上的流动。仿真结果与船体灌注结果的比较表明，将所提出的快速估计方法与Moldex3D相结合，可以准确模拟大型纤维增强塑料(FRP)制品中的树脂流动(变化<8%)。该方法可应用于大型风力机玻璃钢部件和大型游艇玻璃钢部件，提高工艺规划效率和产品稳定性。
