玻璃纤维蜂窝斜接挖补结构拉伸性能研究
Research on the Excavation and Repair Performance of Glass Fiber Honeycomb Sandwich Structure
摘要
Abstract
The cellular sandwich structure is more and more widely used in the field of modern aviation and aerospace.It is urgent to adopt reasonable repair technology to repair and evaluate the bearing capacity of the repaired structure in the face of various kinds of damage caused in the process of manufacturing and aircraft service.In this paper,the load-bearing capacity of glass fiber honeycomb structure after repair is tested by using self-designed tensile fixture.The results show that the strength recovery rate of the structure after repair can reach 100%,which verifies the effectiveness of the repair technology applied to the composite structure.Then,the progressive damage analysis model of the glass fiber honeycomb sandwich structure under tensile load is established.The simulation results are in good agreement with the experimental results,which verifies the accuracy of the finite element model and the VUMAT subroutine written for the braided composite.关键词
