Shaping technology of ice hockey stick

Abstract

The present invention discloses a forming process of ice hockey stick. Said method includes the following steps: superimposing pre-impregnated composite materials, heating and applying pressure to obtain rough-blank driving board; making the rough-blank driving board is fixedly connected with prefabricated mould of stick body; then using the pre-impregnated composite material to cover exterior of said prefabricated mould of stick body and making the pre-impregnated composite material be lap-jointed with driving head; making bidirectional tensile film be winded round its external surface to obtain the prefabricate of said ice hockey stick; then heating and applying pressure to said prefabricate of said ice hockey stick so as to obtain the invented ice hockey stick.

Description

technical field [0001] The invention relates to a manufacturing process of ice hockey sticks. In particular, a molding process for making ice hockey sticks using composite materials. Background technique [0002] In the ice hockey game, the ice hockey player bends the ice hockey stick and then releases the ball to make the ice hockey move at a higher speed and energy. Therefore, the hockey stick needs to withstand strong strain and stress. The material used to make the stick can greatly improve the performance of the ice hockey stick, further reduce the weight and increase the strength. At present, the main process of using composite materials to make ice hockey sticks is: [0003] 1. After the composite material prepreg is stacked, it is heated and pressurized to form a rough blank striking plate. [0004] 2. Wrap the composite material prepreg on the prefabricated mold of the shaft to make the shaft, and then heat and pressurize it to form a rough shaft. [0005] 3. Cl...

Problems solved by technology

[0008] The above-mentioned process is cumbersome, and multiple processes need to be performed on the connecting parts, which is costly, and the use of glue will affect the mechanical properties of the ice hockey stick during use on the one hand, such as the stiffness of the ice hockey stick, on the other hand it will affect the The structural strength of the ice hockey stick, just because the stick needs to withstand strong strain and stress, may increase the possibility of breaking at the glued position, and it will also affect the energy transmission during the strike, and there will be certain attenuation
