Abstract: PURPOSE: To reduce costs and weight and to improve impact resistance by a method in which a load shearing layer is constituted by curing a filament- wound inner skin, and the flexibility of the layer is increased by the incorporation of a flexible matrix resin so that the inner skin gives both a structural layer and an inside liner to a container. CONSTITUTION: In a filament-wound container like a fuel tank 10, a filament- wound inner skin 38 is wound with a frame barrier 34 and a filament-wound outer skin 36 in turn. The inner skin 38 contains a flexible matrix resin to give both the structural layer and inner liner of the container. The layer 38 not only gives the effective liner to the container but also constitutes its load shearing composition. The load shearing liner layer 38 has flexibility of 20-30% order, which is obtained by modifying an epoxy resin with a softening agent. Thermoplastic resins having similar elongation and environmental compatibility can be used as the flexible matrix resin for the load shearing liner 38.
