PROBLEM TO BE SOLVED: To provide a catheter formed of a braided body having a high bonding strength of a first strand and a second strand even when the thickness of the first strand and the thickness of the second strand constituting the braided body are decreased.SOLUTION: A body of a catheter includes an inner layer, a braided body and an outer layer. The braided body includes a first strand 26a and a second strand 26b. The tip of the first strand covers the side of the second strand to wind around it so that the first strand and the second strand can be bonded to each other. A bonding part 100 includes a bonding part formed at the position of intersection, a bonding part 120 formed at a position exceeding the width direction N of the first strand 26a, and a bonding part 130 formed at a position exceeding the width direction N' of the second strand 26b. Therefore, even when the thickness of the first strand 26a and the thickness of the second strand 26b are decreased to reduce the size of the braided body, the bonding strength of the first strand 26a and the second strand 26b can be secured by increasing the area of the bonding part 120 and the thickness of the bonding part 130.
摘要:
A method of manufacturing a composite structural member (1), comprising the step of laying up a stack of fibre reinforced laminate plies (12), wherein at least one of the plies is laid up as discrete first (13) and second ply (14) portions, and the fibres of the second portion (14) have a different characteristic from those of the first portion (13). Also, a composite structural member (1) manufactured according to the method.

PROBLEM TO BE SOLVED: To provide compound reinforcing fiber base material, which is excellent in shapability and in impact resistance after molding and a pre-form, by which the compound reinforcing fiber base material is employed, in which no disturbance of orientation of fibers develops and which is excellent in handlability and impact resistance when molded. SOLUTION: In the compound reinforcing fiber base material, the reinforcing fiber base material and non-woven fabric, which is made of short fibers and laminated at least on one side of the sheet-like reinforcing fiber base material made of reinforcing fibers, are integrated with each other in such a manner that the short fibers forming the non-woven fabric penetrate the reinforcing fiber base material.
