A kinetic study and the glass-reinforced composites of a liquid diglycidyl ether of bisphenol-P epoxy resin

Abstract

The curing reaction of liquid epoxy resin based on l,l'-bis(4-hydroxyphenyl) cyclopentane with different amines, in the presence or absence of a fortifier, has been studied by differential scanning calorimetry (DSC). The glass-fibre-reinforced composites of liquid diglycidyl ether of bisphenol-P (DGEBP) were prepared using different amines as curing agent with/without fortifier and evaluated for their physical properties (such as density,% resin content and% void content) and mechanical properties (such as flexural strength, interlaminar shear strength and shore-D hardness). The laminates were also evaluated for their chemical resistance and electrical properties. It was found that using an epoxy fortifier (PGEHA) reduces the mechanical properties of the DGEBP-curing agent system.
