Executive Summary The purpose of this project was to design a gas tank to compete in today’s market and to meet future emission regulations. A profitable alternative design to current steel and polymer tanks was obtained. The tank is constructed of a 1.4 mm Curv® (polypropylene product) structure grafted with a maleic anhydride adhesive film, a 0.14 mm barrier layer of ethylene vinyl alcohol, and a 0.3 mm layer of maleic anhydride grafted Curv®. The additional 0.3 mm layer of Curv® is used to protect the EVOH layer from the environment. The tanks are manufactured from preformed sheets of Curv® pressed into the desired shape by thermoform stamping. The EVOH is sprayed onto one sheet of maleic anhydride grafted Curv®, the Curv® layers are combined and stamped. The stamping process produces the tank in two halves which are connected to form one
