This report covers the fabrication of two rigid foam plastics shelters by spray application of plastic resins to the inside sur¬face of air-inflated molds. The first shelter was constructed of sprayed polyurethane foam with steel rib reinforcement. The second shelter was constructed of sprayed glass fiber-polyester laminate with sprayed polyurethane core.nThe report concludes that the disadvantages of the spray method of fabrication far outweigh the advantages.
