Title:
光硬化性中空構造物及びその硬化方法
Document Type and Number:
Japanese Patent JP3615161
Kind Code:
B2
Abstract:
Photo-curable hollow structure comprises inner bag layer allowing fluid to be force-fed therein, substrate layer impregnated with photo-curable resin overlaid on bag, and light permeable covering layer overlaid on substrate. Substrate layer contains fibre reinforced layer impregnated with photo-curable resin, and flowing resistant object is overlaid on reinforced layer to stop resin flowing. Photo-curable hollow structure comprises inner bag layer allowing fluid to be force-fed therein, substrate layer impregnated with photo-curable resin over laid on inner bag layer, and light permeable covering layer overlaid on the substrate, wherein the structure can be wrapped and contained in a light shielding bag or case when not used, and when used, it is taken out of the casing, filled with liquid to expand, and the substrate is cured by irradiating with sun light or artificial light , wherein the substrate layer contains a fibre reinforced layer impregnated with photo-curable resins, and a flowing resistant object is overlaid on the fibre reinforced layer to stop the flowing of the resin. Independent claims are also included for: (1) a similar structure wherein the flowing resistant object is located along the longitudinal direction of the substrate; (2) a similar structure wherein the substrate also contains a partially cured product together with the fibre reinforced layer; (3) a similar structure wherein fibres with high heat conductivity is mixed in the fibre reinforced layer; (4) a similar structure wherein the inner bag is formed into a transparent film by irradiation;and (5) a curing method of the hollow product.
