摘要: 为探究碳纤维复合材料各向异性特性对气泡溃灭形态的影响,利用高速全流场显示系统记录和观测单向纤维铺层的碳纤维复合材料边界附近气泡形态,以及复合材料边界变形随时间变化的过程,对气泡在不同铺层角度复合材料边界附近的形态变化进行分析。在气泡距复合材料边界相同初始距离下,针对铺层角度为0°、90°以及0°+90°交替叠加铺层的3种碳纤维复合材料板,对比了复合材料边界附近气泡的形态变化过程以及复合板变形的差异。研究结果表明:气泡在边界附近溃灭时产生高速射流以及冲击波是破坏边界的主要原因;铺层角度的不同会导致单向纤维复合材料边界的变形方式不同,从而严重影响气泡的形态演化过程以及溃灭方式。

Abstract: In order to study the effect of anistropic properties of composite material on bubble shape, the shapes of bubbles near the carbon fiber composite material boundaries and the deformation of the carbon fiber composite material boundaries were recorded and observed by using high-speed camera. The shapes of bubbles near the composite material boundaries with different ply angles are studied. The changing processes of bubble shape and the deformation modes of the composite material boundaries at the same initial distance of bubble from the boundary are compared for the carbon fiber composite plates with the ply angles of 0°,90° and 0°+90°. The results show that the high-speed jet and shock wave generated by the collapse of bubble near the boundaries are the important factors for the damage of boundaries, and the different ply angles of carbon fiber composite material lead to different deformation modes, which has an important impact on the shapes of bubbles.
