M. Hussain et al., CORRELATION OF MICROSTRUCTURE AND MECHANICAL-PROPERTIES OF AL2O3-DISPERSED POLY(ETHERSULPHONE)-EPOXY BLENDS, Materials letters, 27(6), 1996, pp. 367-371
The microstructure of Al2O3-dispersed poly(ethersulphone)-epoxy blends
has been investigated and was correlated with mechanical properties.
Microstructure analysis and Young's modulus measurements have been use
d to study the microstructural changes of the composites. No phase sep
aration was observed for poly(ethersulphone) filled epoxy system. Howe
ver, precipitated phase, phase separation and phase-inverted microstru
cture were observed for the Al2O3-dispersed poly(ethersulphone)-epoxy
system depending on the concentration of Al2O3 and poly(ethersulphone)
. Mechanical properties showed the dependence upon the microstructure
of the composites.
