複合材料用三次元織編組物及び複合材料
Document Type and Number:
Japanese Patent JP4402252
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a fibrous material capable of eliminating trouble caused by a forming step with conventional materials for composite materials because a sufficient strength among the materials cannot be obtained or there is trouble requiring much operation labors and time by adding the dividing of a product of a complicated shape into elements of a simple form and preforming operations such as a laying up operation or a debulking operation for each form element when the product of the complicated shape is produced though there are methods for cutting a sheetlike material called a prepreg, laminating the cut sheetlike material into the form of the product and forming the resultant laminate in methods for producing a fiber-reinforced composite material product in relation to the fibrous material for the composite materials for producing the fiber-reinforced composite material product and a structural part. SOLUTION: This three-dimensional woven or knitted braid for the composite material is obtained by arranging binding force improving fibers 2 having functions to improve the toughness strength of a joining surface and improve the breaking strength in reinforcing fibers 1 formed into a constituent member for forming the fiber-reinforced composite material product and capable of providing the constituent member with a high strength and a high modulus of elasticity. Thereby, the joining area among the materials is reinforced and the fiber-reinforced composite material product having a high breaking strength can be provided at a low cost to eliminate the trouble.
