METHOD FOR MANUFACTURING HONEYCOMB MADE OF FIBER-REINFORCED RESIN, HONEYCOMB MANUFACTURED BY THIS METHOD, HONEYCOMB SANDWICH STRUCTURAL BODY MADE OF FIBER-REINFORCED RESIN, AND COLUMN MATERIAL, BEAM MATERIAL OR WALL MATERIAL FOR STRUCTURE OR DECORATION

摘要

PROBLEM TO BE SOLVED: To provide a means for directly manufacturing a high-strength honeycomb made of a fiber-reinforced resin which has hexagonal cells with good shape precision and keeps the cells strongly sticking together, from a prepreg.

SOLUTION: A prepreg laminated body in which a number of molding tubes are inserted at positions of hollow cells is pinched by an outer retaining frame, and the molding tubes are pressed under a gas pressure to deform the prepreg into a honeycomb shape, and then, the resin of the prepreg is cured to manufacture the honeycomb shape. In addition, the molding tubes are expanded with a foaming substance filled therein to mold the prepreg into the honeycomb shape, and the molding tubes filled with the foaming substance are left in the hollow parts of the honeycomb cell to manufacture the high-strength honeycomb.
