摘要
针对复合材料长桁毛坯制备的新工艺-叠层滑移工艺,考虑叠层滑移工艺的极限参数规划相关的力学性能试验矩阵,研究叠层滑移工艺对M21C层压板拉伸性能、压缩性能、弯曲性能、短梁剪切性能、开孔压缩性能和面内剪切性能的影响。试验结果表明:叠层滑移工艺对M21C层压板的开孔压缩性能无影响,拉伸性能、压缩性能、弯曲性能、短梁剪切性能和面内剪切性能均会有一定程度的下降。
Aimed at a new process for rough preparation of composite long truss-stack slippage process, the mechanical performance test matrix related to the limit parameter of the stack slippage process was made. The effects of stack slippage process on the tensile properties, compression properties, bending properties, shear properties of short beams, opening-hole compression properties and internal shear properties of M21 C laminates were studied.The experimental results show that the stack slippage process has no effect on the opening-hole compression performance of the M21 C laminates, and the tensile properties, compression properties, bending properties, shear properties of the short beams and the internal shear properties will decrease to a certain extent.
