Title:
MOLDING PRODUCT OF FIBER-REINFORCED COMPOSITE MATERIAL
Document Type and Number:
Japanese Patent JP3641553
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain the subject molding product being lightweight, excellent in strength, high-impact properties and flexibility and useful for a leaf spring, a body for an automobile such as a truck, a passager car or the like, a part for an artificial satellite or the like, by including a specific carbon fiber as a part or the whole of a reinforcing fiber.
SOLUTION: This molding product comprises a carbon fiber having 5-160 GPa tensile modulus, 1-5% compressive breaking strain and 1.5-1.9 g/cm3 density (e.g. a pitch-based carbon fiber) as a part or the whole of a reinforcing fiber. Preferably, the molding product comprises a laminated body consisting of at least one prepreg having the carbon fiber as a reinforcing fiber and at least one prepreg having a fiber except the carbon fiber (preferably a carbon fiber having 200-1000 GPa tensile modulus or the like.) as a reinforcing fiber. An epoxy resin or the like, can be usually used as a matrix resin.
