Abstract

Previously, an algorithm based on two control parameters was applied to computer aided design of materials, and here the algorithm is extended to three parameters controlling the effective physicomechanical properties of polymer matrix composites: (i) the average particle size of a polymer powder, (ii) the length of reinforcing fibers, and (iii) the level of fiber–matrix adhesion. The use of these control parameters is dictated by the possibility of their ranging in terms of degrees of influence on effective material characteristics. The algorithm with built-in experimental data is applied to design a composite with specified properties on the example of ultrahigh molecular weight polyethylene reinforced with milled or chopped glass fibers. The form of data presentation shows the whole range of the three parameters which provides the desired result.

使用三个控制参数设计具有一组指定物理力学特性的复合材料

摘要

以前，基于两个控制参数的算法被应用于材料的计算机辅助设计，这里该算法扩展到控制聚合物基复合材料有效物理机械性能的三个参数：（i）聚合物粉末的平均粒径，（ ii) 增强纤维的长度，以及 (iii) 纤维-基体粘附的水平。这些控制参数的使用取决于它们对有效材料特性的影响程度的范围的可能性。以磨碎或短切玻璃纤维增​​强的超高分子量聚乙烯为例，应用内置实验数据的算法设计具有特定性能的复合材料。
