S. Guhanathan et al., Effect of coupling agents on the mechanical properties of fly ash/polyester particulate composites, J APPL POLY, 82(7), 2001, pp. 1755-1760
Fly ash (FA)/general purpose unsaturated polyester resin (GPR) particulate
composites were made. The effect of the surface treatment of FA with two di
fferent silane coupling agents (CAs) on the mechanical properties, such as
the tensile, flexural, compressive, and impact strengths and hardness, of F
A-GPR composites were studied. The properties of FA-CA-GPR were also compar
ed with that of GPR and CaCO3-GPR. An enhancement in the tensile, flexural,
compressive, and impact strengths and a decrease in the tensile and flexur
al moduli were observed when FA was surface treated with CA. Hardness also
increases with CA-treated FA. (C) 2001 John Wiley & Sons, Inc.
