POROUS STRUCTURE MADE OF THERMOPLASTIC CARBON FIBER RESIN BASE MATERIAL, AND MANUFACTURING METHOD OF THE SAME

PROBLEM TO BE SOLVED: To provide a porous structure which is composed of a composite material, light-weight and high-rigidity, hot-bendable, and used in a filter, a package body, a heat insulation material, a vibration-proof material or a soundproof material, and also provide a manufacturing method of a porous structure, a porous molded body manufactured by molding the porous structure.SOLUTION: There is provided a porous structure has a base material made of a composite material including thermoplastic resin and carbon fiber, and a plurality of through-holes penetrating from one end surface to the other end surface are formed in the structure, in which the total area of openings of the plurality of through-holes is 10 to 90% the total area of the end surfaces, on one end surface and the other end surface. Further, there is provided a manufacturing method of a porous structure in which through-holes are formed by using any one of a metal mold, laser beam and jet water flow. Further, there is provided a porous molded body manufactured by hot press molding or hot bend molding to the porous structure. 【課題】複合材料からなり、軽量かつ高剛性で、熱曲げ加工が可能であり、フィルター、梱包体、断熱材、防振材または防音材に用いられる多孔構造体を提供する。また、多孔構造体の製造方法、および多孔構造体を成形してなる多孔成形体も提供する。【解決手段】熱可塑性樹脂および炭素繊維を含む複合材料からなる基材を有し、一方の端面から他方の端面へ貫通する複数の貫通孔が形成されてなる多孔構造体であって、一方の端面および他方の端面において、複数の貫通孔の開口総面積が、端面の総面積の１０〜９０％であることを特徴とする多孔構造体。また、金属金型、レーザー光線またはジェット水流のいずれかを用いて貫通孔を形成することを特徴とする多孔構造体の製造方法。さらに、多孔構造体を熱プレス成形または熱曲げ加工成形してなる多孔成形体。【選択図】図１
