碳纤维复合材料各向异性特性对气泡形态影响试验研究

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.
