Abstract

The results of an experimental evaluation of the influence of the geometric form of the tubes used for supplying a binder under the molding of parts using vacuum infusion on the flow uniformity of the binder front and on the phase composition of a composite material have been presented. The epoxy binder and basalt fabric were used as initial materials. Three types of tubes for supplying the binder have been considered, namely, regular, spiral, and special (in the form of a distribution stripe). We have presented the schemes of their installation, the patterns of the binder front movement, the results of an expert evaluation of the quality of the impregnation process, and the results of determining the phase composition and interlaminar shear strength. It has been established that the use of a spiral tube and distribution stripe makes it possible to reduce the difference in the phase composition of the basalt–plastic at the sites of installation of the tubes for the input and output of binders makes it possible to obtain the highest values of interlaminar shear strength.

工程支持对使用真空灌注法进行玄武岩塑料成型工艺质量的影响研究

摘要针对真空灌注成型零件时用于供应粘合剂的管子的几何形状对粘合剂前沿流动均匀性和复合材料相组成的影响进行的实验评估结果已经公布。初始材料为环氧树脂粘合剂和玄武岩织物。我们考虑了三种类型的粘合剂供应管，即常规管、螺旋管和特殊管（分布条纹形式）。我们介绍了它们的安装方案、粘结剂前端的运动模式、专家对浸渍过程质量的评估结果，以及确定相组成和层间剪切强度的结果。结果表明，使用螺旋管和分布条纹可以减少粘结剂输入输出管安装位置的玄武岩塑性相组成差异，从而获得最高的层间剪切强度值。
