摘要
Abstract
The effects of different stitch densities and different stitch thread thickness on the in-plane mechanical properties of carbon fiber eight-five-face satin-stitched composite materials were studied.The in-plane fiber waviness due to stitch thread implantation was measured by microscope observation,and the correlation between mechanical properties and in-plane fibers waviness was analyzed.The results show that the stitch has certain influence on the in-plane properties.As the stitch density becomes larger and the stitch thread becomes thicker,the in-plane mechanical properties show a decreasing trend and the decreasing range increases.Microscopic analysis shows that in-plane fiber waviness is characterized by the waviness amplitude and waviness angle in-plane,and the main factors that affect the mechanical properties of stitched laminates is in-plane fiber.Under the same stitch thread thickness,as the stitch density becomes dense,the waviness amplitude of the in-plane fiber is almost unchanged,and the waviness angle of the in-plane fiber increases first and then decreases,and the in-plane mechanical properties decrease as a whole.At the same stitch density,the waviness amplitude and angle of the in-plane fiber increased with the stitch thread thickness,and the decreasing trend of the strength had a strong correlation with the waviness amplitude and angle of the in-plane fiber,where the quadratic function correlation coefficient ranged from 0.89 to 0.97.关键词
