Abstract

To produce a co-poly-para-aramid fiber (AF, Technora®)-reinforced neoprene rubber composite, dispersion of AF in a neoprene matrix is investigated. The AF is then surface-modified by mercerization and acetone, plasma, and silane treatments to improve dispersibility. Finally, an internal mixer process is used to disperse the surface-modified fibers in the neoprene rubber matrix.
