In this research a proper amount solvent has been for Neoprene rubber to give it the required viscosity. Zinc oxide has also been added with different ratios to improve the process of adhesion. We made compound substances on the basis of Neoprene and improved them with glass fibers by means of different ways of solidification, and with different weight ratios by means of manual molding through designing a wooden mould containing five parts with certain measurements, and studying the orientation of these fibers and their effects on some mechanical characteristics of Neoprene rubber.
