BOLT HOLE REINFORCED MOLDING METHOD OF COMPOSITE-MATERIAL LAMINATED PLATE

摘要

PURPOSE: A bolt hole reinforced molding method of a composite-material laminated plate is provided to keep the degree of strength with simplicity and the plate is made of the composite-material like a carbon fiber, etc. CONSTITUTION: A bolt hole reinforced molding method of a composite-material laminated plate is designed to hold the surround area penetrating the bolt hole by being stuck to the composite-material made a plurality of projections of carbon fiber. A forming step forms a penetrating hold(2) on a base-plate loaded laminated plates fit for a bolt forming position of the laminated plate. An inserting step inserts a position fixing pin slantly formed as a conic head in the penetrating hold. A reaching step duly has a taper-typed center section forming a bolt molding hole swollen from the edge area of the surroundings and couples a reinforced steel forming the plurality of projections on the whole convex side with the head section of the position fixing pin toward the upper direction. A fixing step fixes the projections on the reinforced steel on the laminated plate with loading the composite-material laminated plates on the reinforced steel. And a forming step forms the bolt hold on the laminated plate through the bolt molding hole formed in the center of the reinforced steel.
