A high temperature adhesive was prepared by adding ceramic powders (SiC, ZrC, Si or Zr etc. ) to
polycarbosilane. Its rheology investigated by rheometer, The properties and relationship between component and properties
of adhesive were investigated by means of TGA, XRD and SEM. The results suggested that adhesive possessed
good high temperature resistance and adhesive intensity. The weight loss was 16wt% in 1 200℃(N2 atmosphere),and
its adhesive intensity was 6. 4 MPa.
