纤维曲线铺放的变刚度复合材料层合板的屈曲

THE BUCKLING OF VARIABLE-STIFFNESS COMPOSITE PANELS WITH CURVILINEAR FIBER FORMAT

本文介绍了一种纤维曲线铺放的变刚度复合材料层合板的概念,利用这种新的铺放方法所引起的复合材料层合板面内应力的重新分布,提高了复合材料层合板的屈曲载荷。并且利用ABAQUSTM软件对这种纤维曲线铺放的复合材料层合板进行了建模计算,验证了其面内受力情况下,屈曲载荷显著提高,幅度达14%左右。

This paper presents a study on the concept of variable-stiffness with curvilinear fiber format. Based on that concept, the redistribution of stress field occurs, which improves the buckling load of the laminated composite panels. By using ABAQUSTM, it proves the model of the concept and shows that the increment of the buckling load is significant, which is 14%.
