Abstract:

To investigate the effect of the additive content in sizing agent and the percentage by weight of size on the surface and weavability of SiC fibers, the domestic KD-I SiC fibers were sized with waterborn epoxy resin sizing agent by two times of sizing treatment. Tensile abrasion resistance, strength and elongation and flexibility were strdied. The results indicate that SiC fibers sized with E-15 sizing agent exhibit highee abrasion resistance and better flexibility than those unsized and sized with E-0, E-10, E-20 sizing agents. It is also found that the percentage by weight of size has significantly influence on the surface morphology of SiC fibers. The SiC  fibers sized with 9 % E-15 sizing agent which is considered as the optimum dosage, and the tensile strength of SiC fibers is enhanced about 180% compared with that of the unsized.

Key words: waterborn epoxy resin, sizing, SiC fiber, weavability, abrasion resistance
