铺丝伴生楔形间隙/搭接缺陷对复合材料疲劳性能影响研究OA

For the unvoidable edge gap/overlap defects in automatic wire laying process,affecting the quality of the component and bringing uncertainty to its mechanical properties,this paper,taking samples containing wedge-shaped gaps/overlap defects as the research subject,explores the effects of different defect sizes on the fatigue properties of composite materials by combining experiments and finite element simulation methods,which provides theoretical basis for the establishment of allowable values for composite materials and wire breaking strategy for automatic wire laying technology.
