Abstract: PROBLEM TO BE SOLVED: To provide a container which is light in the weight and strong in the strength and excellent in the heat-insulation property, by forming at least the side plates of the container with fiber-reinforced plastics and specifying the thickness of the sheet and the volumetric content ratio of the fiber material within a certain range. SOLUTION: At lest the thickness of the fiber reinforced plastics(FRP) sheet constituting the side plates 2 of a container 1 is set within 0.1-1.5mm and the volumetric content ratio of the fiber is set within 25-65%. If the thickness of the FRP sheet is thinner than 0.1mm, it is difficult to give a high piercing- resistant strength and if the thickness is thicker than 1.5mm, the lightening effect is lessened. If the volumetric content ratio of fiber is lower than 25%, since the volume of the reinforcing fiber is lessened, a specified strength can not be obtained. When the thickness is increased to obtain a specified strength, the lightening effect can not be obtained. The thickness of the FRP sheet is most preferable in the range of 0.3-0.8mm and the volumetric content ratio of fiber is preferable in 30-60%.

Abstract: PURPOSE:To perform high-efficient and smooth pressurization and heating of a composite material, by a method wherein a roll for pressing a composite material and a heater for locally heating the composite material are mounted to a part of a traverse mechanism. CONSTITUTION:After a composite material 11 from a creel and the like is carried through a guide roll 61 of a support frame 60 mounted to a traverse head 5, it is pressed against a mandrel 1 by a pressure roll 6 with the aid of a press means 8, and is wound as it is traversed. In this case, The composite material 11 right before a pressure position allowing it to be pressed by the pressure roll 6 is locally heated to temperature being higher than a melt point of matrix resin by means of a heater 7 for local heating mounted to a support frame 60 through an arm 70. The composite material is pressed by means of the pressure roll 6, the composite material of a layer wound around the mandrel 1 is thermally fused to the composite material 11 of a new layer, and moulding is effected simultaneously with winding. This constitution enables high-efficient and smooth pressurization and heating of the composite material, and improves productivity of moulding of the composite material.
