| Abstract: | The interface debonding force of Nicalon SiC/7740 glass composite was measured by mi-
cro-debonding test. The bond shear and tensile strength along fiber axis within the thickness
of specimen was calculated from a simplified micromechanics finite-element analysis by SAP
5 program in SIEMENS 7570 C calculator. Compared with the results from literatures and in
view of the difference of heat-expansion coefficients of composite components, the calculated
results was analysed |

| Keywords: | composite interfacial bond stress finite-element analysis |
