Dry winding based production process for carbon fiber arrow shaft

Abstract

The invention discloses a dry winding based production process for a carbon fiber arrow shaft. The process comprises the following steps: a, combining carbon fibers with epoxy resin in proportion andperforming rolling-up quickly; b, performing sealed packaging and freezing a product in a warehouse; c, unfreezing the product in advance and directly placing the product on processing equipment for winding processing to obtain the arrow shaft. The arrow shaft is prepared directly with a dry method, so that limitation that raw materials in a workshop have to be prepared for use is omitted, pollution of volatile molecules in the workshop is reduced, the workshop is more environmentally friendly, quality of the arrow shaft is improved, and material loss is reduced.

Description

technical field [0001] The invention relates to the field of preparation of environmentally friendly materials, in particular to a process for manufacturing carbon fiber arrow shafts by dry winding. Background technique [0002] Arrow shafts have always been an indispensable tool for hunting and shooting sports, and are mainly composed of shafts, arrows, and pinnae. [0003] The earliest arrow shafts were made of solid wood. Later, with the evolution of the market, hollow metal shafts appeared. Later, hollow structures became the norm for shafts. With the continuous development of materials science, glass fiber or carbon materials were used instead of metal. Rod bodies have also become very standardized. [0004] However, due to the inherent characteristics of carbon fiber or glass fiber materials, it is difficult to control the straightness and rigidity of arrow shafts made of such materials. [0005] The definition of straightness: straightness refers to the amount of ch...

Problems solved by technology

[0007] Disadvantages of poor straightness: it will affect the flight trajectory. Such a defect is fatal. When the user is hunting or shooting, the arrow will be affected by factors such as wind resistance when moving in the air. Experienced athletes will seek the best Arrow shaft with the best flight path for the most accurate shooting target

[0009] The disadvantage of poor deflection is that since the arrow shaft is placed in the middle of the bow when it is fired, it is under a lot of stress when it is released and before the arrow enters the target

[0011] However, the disadvantage of this wet process, that is, processing while impregnating, is that the amount of fiber impregnated with resin cannot be effectively controlled due to the wet process of winding carbon fibers through the resin tank, which will cause very large differences in weight, strength, rigidity, and straightness of semi-finished products. The difference needs to increase the amount of grinding, which directly causes the instability of weight and straightness

Moreover, the workshop for processing and producing arrow shafts also pollutes the production environment due to the volatilization and dripping of epoxy resin and its additives

[0012] Due to the large deviation of resin impregnation, after the carbon fiber arrow shaft is cured, the weight, strength, rigidity and straightness of the arrow shaft have a large dispersion rate, so the increased grinding amount is required to increase the proportion of defective products; weight, strength, The large difference in rigidity and straightness also produces a variety of grades of finished products, which need to be re-divided according to different types, which greatly increases labor costs
