项目摘要

In order to develop a High Performance Cementitious Composites (HPCC), material design criteria were studied. For possessing light weight, high strength and high toughness, micromechanics approach was introduced. Mix proportion of matrix was discussed on the basis of packing theory and various types of fibers were experimentally studied Effect of processing was also investigated.The following results were obtained.(1) Packing theory works well to find a suitable mix proportion to produce a dense matrix to achieve high strength matrix(2) Not only the performance of matrix and fiber, but also the suitable combination of these two components are very important to produce HPCC.(3) Exclude processing is very useful to produce HPCC.(4) Experimental results were analyzed by a multi regression analysis to formulate design criteria for five performance indexes that are the maximum flexural strength, deformability, and three toughness indexes.
为了研制高性能水泥基复合材料,对材料设计准则进行了研究。为了获得轻质、高强、高韧的复合材料,引入了细观力学方法。本文根据填充理论讨论了基体的配比,并对不同类型的纤维进行了实验研究,对加工效果进行了探讨,得出了以下结论。(1)填充理论可以很好地找到一个合适的混合比例,以产生致密的基体,以获得高强度的基体。(2)生产HPCC不仅要考虑基体和纤维的性能,而且要考虑这两种组分的合适组合。(3)预处理是生产HPCC的有效方法。(4)试验结果进行了多元回归分析,制定设计准则的五个性能指标,即最大弯曲强度,变形能力,和三个韧性指标。
