【摘要】 在树脂传递模塑工艺(RTM)的充模流动中,纤维预制体的渗透率系数是一个重要的参数,它综合反映了流动中树脂和纤维所有的相互作用。本文以Darcy定律为渗透率系数测定的基本原理,自行设计了实验装置和模具,对恒定流速作用下树脂在多层玻璃纤维方格布中的一维面内流动的渗透特性进行了实验研究,分别考虑了不同恒定流速和不同纤维体积百分含量(或空隙率),并对不同恒定流速作用下得到的渗透率的结果进行了分析比较,得出了一些有意义的结论。更多还原

【Abstract】 During the resin flow of Resin Transfer Molding,the permeability of fiber performs is an important parameter,which reflects the interaction between the resin and fiber. In this paper the Darcy’s law was used as the fundamentals to determine the permeability of fiber performs,an experiment installation was designed, and do some experimental study on the one-dimensional permeability of resin in the multilayer fibrous plaids at a constant flow rate. The installation was designed base on condition of different flow rates and different fiber volumes ( or porosity) ,and compared the results of the permeability of different flow rates. Then results were analyzed,and some content conclusions were obtained.更多还原
