Abstract

In order to compare the effects of two setting methods,nylon thread setting and sizing agent setting,of T800 thin carbon fabric(CF),two kinds of epoxy prepregs and composites were prepared.The fiber arrangement was characterized and analyzed by 3D optical image projector and metallographic microscope.The mechanical properties of the composites were tested and compared.The results shown that compared with the thin fabric shaped in nylon thread setting method that only the fiber bundles in weft direction were partially fixed,the other one shaped by sizing agent had smaller light transmittance with more compact and stable fiber arrangement,and its composite performed better mechanical property in warp direction,whose tensile strength in warp direction was 30.2% higher than that of the former.However,there was no significant difference in the fluctuation of weft deviation angle and the mechanical properties in weft direction of two kinds of composites were basically same.The different arrangement of warp and weft fibers resulted in the fluctuation of the above mechanical properties.
