The Effect of Ply Angle Declination on Deformation of Cure Composite Structure

  • 摘要: 本文阐述了铺层角度偏差对某变厚度曲面结构复合材料固化变形的影响。对铺层角度偏差的来源进行了归纳,采用考虑热膨胀和固化收缩的固化变形计算模型,对该变厚度的复合材料曲面层合板结构的固化变形进行了计算,计算结果与试验结果较为吻合,表明了计算模型的准确性。采用均匀试验设计方法,得到了该曲面结构铺层角度偏差在5°以内变化时的实验方案,对实验设计的计算结果进行了回归分析,结果显示,对于该曲面复合材料结构,总体上铺层角度偏差对固化变形的影响不大,相对的,-45°的铺层偏差对固化变形的影响较大,90°的铺层偏差对固化变形的影响较小。
    Abstract: The effect of ply angle declination on deformation of a curved composite laminate with varied thickness has been studied in this paper.The resources of ply angle declination were drawn.was caculaled with a model in which thermal expansion and curing shrinkage was considered.The cure deformation of the composite curve laminate.The caculated result is conformed with experiment test,showing the calculation model is approvable.By using the uniform design,the design of experiments was achieved when the ply angle declination with in 5 degree of each ply angle.The regression was used to analysis the result of the design of experiments,which shows that in general,ply angle declination has few effect on cure deformation,relatively the ply angle declination of-45 degree has more effect on cure deformation than ply angle declination of 90 degree does.
