Embodiment 1

[0034] The invention provides a fiberglass bow, see attached figure 1 , including a bow arm 1, two bow tips 2 symmetrically arranged at both ends of the bow arm 1, a bow string 3 connecting the two bow tips 2, and a handle bonded to the bow arm 1; the bow arm 1 is made of glass fiber As, the bow tip 2 is made of wooden material.

[0035] Advantageously, the bow arm 1 is formed by pressing unidirectional fiberglass fibers; the bow tip 2 is bonded separately to the bow arm 1 .

[0036] The present invention also provides a processing method of the FRP bow, comprising:

[0037] Step 1, designing the bow shape according to the mechanical properties of the bow;

[0038] Step 2, according to the arch in step 1, design the metal mold, and obtain the finished metal mold;

[0039] Step 3, glass fiber is immersed in resin glue, and the weight ratio of resin glue and glass fiber is 2:1;

[0040] Step 4, manually put the glass fiber immersed in the resin glue in step 3 into the mold c...

Embodiment 2

[0051] The invention provides a fiberglass bow, see attached figure 1 , comprising a bow arm 1, two bow tips 2 symmetrically arranged at both ends of the bow arm 1, a bowstring 3 connecting the two bow tips 2, and a handle bonded to the bow arm 1; the bow arm 1 and the bow tip 2 All are made of fiberglass.

[0052] Advantageously, the bow arm 1 and the bow tip 2 are integrally formed, both of which are formed by pressing glass fibers with unidirectional fiber directions.

Abstract

The invention relates to a glass fiber reinforced plastics bow comprising a bow arm made of glass fiber, two bow tips symmetrically disposed at two ends of the bow arm, a bow string connected with thetwo bow tips and a grip attached to the bow arm. The bow tips are made of a wood material or glass fiber. The invention also provides a glass fiber reinforced plastics bow machining method. A glass fiber reinforced plastics forming process is applied to the machining of a traditional bow; the bow arm is made of glass fiber reinforced plastics by an integrated hot-pressing process, the glass fiberreinforced plastics are not affected by the external environment and temperature and mechanical properties of the glass fiber reinforced plastics bow are not affected by ambient temperature and humidity changes when the glass fiber reinforced plastics are stored or used, so that the glass fiber reinforced plastics bow not only improves environmental weather resistance, but also prolongs service life, and meets the use requirements of bow enthusiasts.

Description

technical field [0001] The invention relates to the technical field of traditional bow manufacture, and more specifically relates to a fiberglass bow and a processing method thereof. Background technique [0002] The production of ancient Chinese traditional bows is made of animal and plant materials, which are usually called horn bows. Although this process is very strict in material selection, it is difficult to guarantee the quality of the product due to the divergence of the physical properties of animal and plant materials; and the temperature and humidity of the environment have a great impact on natural animal and plant materials, such bows from hot From the cold summer to the cold winter, the strength can vary by more than 20 percent; in the production of bows, the requirements for craftsmen are very high, the working hours are quite long, and the cost is extremely high; at present, the price of a good horn bow is More than 10,000 yuan; in addition, for the maintena...
