In common glass fiber reinforced polyolefine pipe, when the volume faraction is less than the critical value, the glass fiber can not act as reinforcement, on the contray, it would reduce the whole intensity of the compound material. However, when extruded in combined stress field, the extend intensity of the compound system increases when the volume fraction of glass fibers is less than the critical value. When the glass fiber volume fraction is higher than the critical value, the required glass fiber volume fraction of compound fibers extruded in the combined stress field is less than theory value.
一般玻璃纤维增强管材在常规挤出时当添加的玻璃纤维体积含量小于临界体积分数(当添加的玻纤的复合体系拉伸强度等于基体聚合物材料的拉伸强度时的玻纤体积分数)时,玻纤起不到增强的作用,反而会使复合材料的整体强度降低;但在复合应力场下挤出时,当添加的玻纤含量小于临界体积分数时,复合体系的拉伸强度不但没有降低反而升高了;当添加的玻纤含量大于临界体积分数时,复合体系要达到同样强度,经过复合应力场的玻纤增强管材需要的体积分数小于理论值。
