法に関する。[Detailed Description of the Invention] [Technical Field of the Invention] This invention relates to fiber reinforced plastics (hereinafter referred to as
This article relates to a method for manufacturing a handle for a Western bow made of FRP (abbreviated as FRP).

Conventionally, when molding the handle of this type of Western bow, especially an assembly-type Western bow in which the handle and rim can be freely separated, a core made of foamed synthetic resin or the like is molded into a core shape that is almost similar to the shape of the handle. Attach raw material for FRP molding (refers to reinforcing fibers impregnated with uncured liquid synthetic resin for matrix and semi-cured as necessary) around the component,
The handle molding material is inserted into a mold, clamped, and hot-press molded.

安定性および操作性に劣るなどの問題点があつ
た。 However, in the case of the above-mentioned conventional forming means, the surface of the core component material, especially the front and rear surfaces corresponding to the target side and the string side, is formed by forming side windows in the vertical direction (vertical direction). When attaching raw material for FRP molding to a surface that is partially bent in the horizontal direction,
The handle body 1 is made by cutting out a single layer of reinforcing fiber such as cloth along the surface shape of the handle and laminating it into multiple layers, as illustrated in FIG.
The longitudinal fibers a of the FRP attached to the front and rear surfaces of the side window portion 2 forming portion become discontinuous, thereby providing the handle with a strength that requires a bending strength of approximately 5.0 kg/mm 2 or more. Therefore, the overall weight of the handle increases, as the bending strength must be compromised by increasing the wall thickness.
There were problems such as poor stability and operability.

は不可能であつた。 In addition, in view of the drawbacks of such conventional forming means, even if one attempts to bend the reinforcing fibers of a roving sheet or cloth as they are along the surface shape of the handle, the reinforcing fibers do not follow the surface shape of the handle; Furthermore, it was impossible to attach multiple layers.

This invention was made under the above circumstances, and is for use in western bows, in which the longitudinal fiber arrangement of the reinforcing fibers can be continuous even in the curved portion of the handle surface, and can be attached in multiple layers. The purpose of this invention is to provide a method for manufacturing a handle.

As explained above, according to the present invention, a rod shape is formed by winding a single layer or multiple layers of reinforcing fibers made of a strip material such as a roving sheet, cloth, or roving cloth impregnated with an uncured liquid synthetic resin for matrix. A plurality of bars are bent and attached in parallel along at least the surfaces corresponding to the target side and the string side of the core component material bent into the shape of a handle, and a cross is attached to one or both of the parallel surfaces of these bar-shaped materials. Alternatively, a handle molding material can be molded by overlapping unidirectional fiber sheets, and the handle molding material is inserted into a mold, clamped, and heated to form a handle. Since the reinforcing fibers can easily follow the curved surface of the core component, the reinforcing fibers can be arranged continuously in the vertical direction of the handle. Because it is possible to partially concentrate reinforcement on specific surfaces corresponding to the target side and string side, such as the handle of the play.
