Traffic signal housing and road sign obtained using high-strength fibre composite

Abstract

Provided are a traffic signal housing and a road sign which are higher in weather resistance and lighter in weight as compared with conventional traffic signal housings and road signs using metal plates. A traffic signal housing and a road sign each made of a high-strength fiber composite in which a surface of a prepreg in which a thermoplastic resin has been combined with a sheet-shaped high-strength fiber including carbon fiber or basalt fiber has been coated with a thermosetting resin, wherein the prepreg is one prepared b thermally pressing a laminate in Which a sheet-shaped thermoplastic resin and said sheet-shaped high-strength fiber have been laminated together in a sandwich structure, are high in weather resistance to salt damage and so on, and moreover since they are lightweight, poles with reduced strength can be used therefor.

1 . A traffic signal housing made of a high-strength fiber composite which comprising a surface of a prepreg in which a thermoplastic resin has been combined with a sheet-shaped high-strength fiber comprising carbon fiber or basalt fiber has been coated with a thermosetting resin, wherein the prepreg is prepared by thermally pressing a laminate in which a sheet-shaped thermoplastic resin and said sheet-shaped high-strength fiber have been laminated together in a sandwich structure. 
     
     
         2 . The traffic signal housing according to  claim 1 , wherein the thermoplastic resin is one selected from among acrylic resin, vinyl chloride resin, vinylidene chloride resin, polyacrylonitrile resin, polyamide resin, polypropylene resin, thermoplastic polyimide resin, polyethylene terephthalate resin and polycarbonate resin. 
     
     
         3 . The traffic signal housing according to  claim 1 , wherein the thermosetting resin is one selected from among epoxy resin, phenol resin, thermosetting polyimide resin, unsaturated polyester resin, urea resin and melamine resin. 
     
     
         4 . The traffic signal housing according to  claim 1 , wherein the number of the laminations of the high-strength fiber sheet is 5 to 100. 
     
     
         5 . A road sign made of a high-strength fiber composite which comprising a surface of a prepreg which as thermoplastic resin has been combined with a sheet-shaped high-strength fiber comprising carbon fiber or basalt fiber has been coated with a thermosetting resin, wherein the prepreg is one prepared by thermally pressing a laminate in which a sheet-shaped thermoplastic resin and said sheet-shaped high-strength fiber have been laminated together in a sandwich structure. 
     
     
         6 . The road sign according to  claim 5 , wherein the thermoplastic resin is one selected from among acrylic resin, vinyl chloride resin, vinylidene chloride resin, polyacrylonitrile resin, polyamide resin, polypropylene resin, thermoplastic polyimide resin, polyethylene terephthalate resin and polycarbonate resin. 
     
     
         7 . The road sign according to  claim 5 , wherein the thermosetting resin is one selected from among epoxy resin, phenol resin, thermosetting polyimide resin, unsaturated polyester resin, urea resin and melamine resin. 
     
     
         8 . The road sign according to  claim 5 , wherein the number of the laminations of the high-strength fiber sheet is 5 to 100.
