1.Since a mutual diffusion between adhesive layer and matrix and a innerstress on interfaces exist,there is a optimal thickness of adhesive layer in composites.
由于聚合物粘层聚合物的相互扩散以及界面内应力的存在,复合材料中存在一个最佳的聚合物粘层。
2.Streak cathod method which is a kind of qualitative method for measuring the innerstress of deposits was introduced.A semi-quantitative calculating formula for the innerstress was given.
