Cure Characteristics and Mechanical Properties of Short Nylon-6 Fiber Neoprene Rubber Composite Containing Epoxy Resin as Bonding Agent

ABSTRACT

Cure characteristics and mechanical properties of the short nylon fiber reinforced neoprene rubber with and without epoxy bonding agent at various fiber loadings were studied. The fiber loading was varied from 0 to 30 phr and the resin content was in the range 0 to 5 phr. Minimum torque and cure time were increased in the presence of resin. Mechanical properties like tensile strength and abrasion resistance showed an increase with resin concentration. It was found that epoxy based bonding agents enhanced the properties of short nylon fiber reinforced neoprene rubber.

Notes

*Epoxy resin formed by 1:0.5 equivalent combination of epoxy resin and amine type hardener; CR-neoprene rubber (zinc oxide – 5 phr; stearic acid – 1 phr; magnesium oxide – 4 phr ethylene thiourea – 0.5 phr are common to all mixes).
