| Summary: | 碩士 === 國立中央大學 === 化學工程學系 === 84 === The goal of this endeavor is to enhance epoxy resins
toughness withinorganic fillers and core-shell rubber(CSR).
Submicron inorganic fillers withvarious particle size of magnium
hydroxide,magnium oxide and aluminum areutilized. The toughness
enhancement is discussed. It was demonstrated that the
higher the amount of methylacrylic(MAA) group on the CSR shell,
the better the dispersion of the CSR in cured epoxyand the
better the toughness enhancement. Furthermore, for epoxy resins
with core-shell rubber at 7.5phr,addition of a limited amount of
inorganic fillers(<3vol%) was found to greatly enhance their
toughness. This is demonstratedthrough a crack deflection
mechanism. Furthermore, the effect of the filler contents
and particle size on the toughness enhancement, tensile strength
and Young's modulus of the epoxyresins are discuessed. The
effect of inorganic filler on toughness enhancementis also
observed in unsaturated polyester(UP) system.
