摘要

拉伸剩余强度是复合材料层合板的一个重要力学性能，对产品的使用寿命起着关键作用。为了研究钻削工艺参数对碳纤维复合材料（Carbon Fiber Reinforced Plastics

CFRP）层合板钻削后拉伸剩余强度的影响，将所选用的失效准则和刚度退化模式编写Vumat子程序，在Abaqus软件中建立了CFRP层合板钻削后拉伸有限元模型。通过正交试验探究主轴转速、进给量和钻头顶角对CFRP层合板钻削后拉伸剩余强度的影响。研究结果表明，主轴转速、进给量和钻头顶角都对层合板拉伸剩余强度有显著影响，提高主轴转速，减小进给量和钻头顶角都可以有效地提高层合板钻削后拉伸剩余强度，为实际加工提供参考。

Abstract

The tensile residual strength is an important mechanical property of composite laminates and plays a key role in the service life of the product. In order to study the influence of drilling process parameters on the tensile residual strength of carbon fiber composite laminates after drilling

Vumat subroutine was written with the selected failure criteria and stiffness degradation mode

and the finite element model of tensile of carbon fiber composite laminates after drilling was established in Abaqus software. The effect of spindle speed

feed rate and bit tip angle on the tensile residual strength of carbon fiber composite laminates after drilling were investigated by the orthogonal test. The results show that spindle speed

feed rate and bit tip angle all have significant effects on the laminate's tensile residual strength. Increasing spindle speed and decreasing feed rate and bit tip angle can effectively improve the laminate tensile residual strength after drilling

which provides a reference for practical processing.
