摘要
复合材料传动轴增强材料采用三维玻璃纤维编织物,其壁厚较厚且内部形状复杂,无法通过VARTM工艺一次整体成型,提出利用气囊代替刚性芯模结合VARTM工艺制造。设计了该产品的成型模具,并对其成型工艺进行了较详细的分析和研究。对整体制备出的复合材料传动轴的性能测试表明,与VARTM工艺相比,气囊/真空辅助RTM工艺能通过气囊膨胀的挤胶作用,降低制品的胶含量和孔隙率,提高制品的力学性能。
The transmission shaft s shape is complicated and its reinforced fiber is 3-D braid.It is unable to be fabricated by traditional VARTM.So the mould design,which used bladder instead of a metal mandrel,is introduced.The property experiment on the integrally fabricated transmission shaft shows that compared with traditional VARTM,the bladder/VARTM process improves the fiber volume fraction by squeezing the resin out through an inflated expansion of bladder.As result the mechanical properties of the composites are improved.
