Method for making composite material bat

Abstract

The invention relates to a method for manufacturing a composite material bat. The method comprises: firstly, weaving a single-layer woven hose; secondly, sleeving a plurality of layers of the woven hoses onto a core material and fixing the two ends of the woven pipes; placing the woven hoses and the core material in a resin groove to allow the resin to penetrate the woven hoses uniformly by resin impregnation (high pressure or vacuum) mode; heating and drying the woven hoses, drawing the woven hoses away from the core material and placing the woven hoses into a mould to form the bat. The method can save labor hours, increase the bat strength, reduces the deflection angle of the bat when the bat is lift to hit a ball and improves the hitting effect.

Description

technical field [0001] The invention relates to a manufacturing method of a composite material bat, which can increase the strength of the bat and improve the striking effect while reducing the processing time and lowering the manufacturing cost. Background technique [0002] Baseball has always been loved by the public, and the more people are attracted to this sport, as far as baseball is concerned, it can be divided into two types: amateur and professional. Because professional baseball emphasizes high technology, the bat used It is limited to wooden bats, and the hitting performance depends on the quality of its hitting skills, while amateur baseball can use metal bats or bats made of composite materials. The method of making composite material bats is After lamination into rods, the rods are placed in the mold for molding. The existing rod manufacturing is shown in Figure 1. The fiber yarn is impregnated with resin and then woven into fiber cloth, and then cut out a plu...

[0002] Baseball has always been loved by the public, and the more people are attracted to this sport, as far as baseball is concerned, it can be divided into two types: amateur and professional. Because professional baseball emphasizes high technology, the bat used It is limited to wooden bats, and the hitting performance depends on the quality of its hitting skills, while amateur baseball can use metal bats or bats made of composite materials. The method of making composite material bats is After lamination into rods, the rods are placed in the mold for molding. The existing rod manufacturing is shown in Figure 1. The fiber yarn is impregnated with resin and then woven into fiber cloth, and then cut out a plurality of pieces. After that, as shown in Figure 2, fiber cloth 1 of various shapes is attached to the core material 2 in sequence, then pulled out, and placed in a mold to form a finished bat. This method has always been It has been used by the industry, although it can indeed be made into a finished bat, but this method, after weaving the fiber cloth with the fiber yarn, is cut into many pieces of fiber cloth of different shapes, and then the fiber cloth is manually processed. The step of attaching a tubular body, and in the process of attaching the fiber cloth, the overlapping parts of each fiber cloth have a certain size. If the overlapping parts are too small, after the bat is made, the joint The strength of the bat will naturally be weak, resulting in the disadvantages of peeling and damage of the finished bat due to the collision force of the impact, and the attachment of the fiber cloth needs to rely on skilled technical workers, and the manual attachment is also time-consuming , because it needs to be completed manually, it will cause an increase in manufacturing cost, so it is really necessary to improve
