Embodiment 1

[0009] Example 1: 50 parts of untwisted glass fiber rovings were impregnated with 90 parts of DERAKANE411, 0.5 parts of BPO, and 1.5 parts of TBPB in parts by weight; B. The mixture obtained in step A was produced through the arch piece forming die at a pultrusion speed of 10 cm / min For the semi-finished product, the mold temperature is controlled at: 1st stage: 70°C, 2nd stage: 120°C, 3rd stage: 80°C; C. Grinding and spraying the semi-finished product obtained in step B to make bow pieces.

Embodiment 2

[0010] Example 2: By weight, 70 parts of untwisted glass fiber rovings were impregnated with 110 parts of DERAKANE411, 1.5 parts of BPO, and 0.5 parts of TBPB; B. The mixture obtained in step A was produced through the arch piece forming die at a pultrusion speed of 50 cm / min For the semi-finished product, the mold temperature is controlled at: 1st stage: 120°C, 2nd stage: 150°C, 3rd stage: 140°C; C. Grinding and spraying the semi-finished product obtained in step B to make bow pieces.

Embodiment 3

[0011] Example 3: 60 parts of untwisted glass fiber rovings were impregnated with 100 parts of DERAKANE411, 1 part of BPO, and 1 part of TBPB in parts by weight; B. The mixture obtained in step A was produced through the arch piece forming die at a pultrusion speed of 30 cm / min For the semi-finished product, the mold temperature is controlled at: 1st stage: 75°C, 2nd stage: 135°C, 3rd stage: 110°C; C. Grinding and spraying the semi-finished product obtained in step B to make bow pieces.

Abstract

The invention discloses a method for manufacturing an arcualia for a crossbow. The method comprises the following steps: A, according to weight portion, 50 to 70 portions of fibre is soaked in 90 to 110 portions of matrix resin; B, the matrix resin and the fibre in the step A are processed by an arcualia forming mould according to drawing and extruding speed of between 10 and 50 cm / min to produce a semifinished product; and the temperature of the mould is controlled by three stages; and C, the semifinished product manufactured by the step B is polished and sprayed to form the arcualia. The method has a simple manufacturing process, easy operation and low cost and is suitable for popularization.

Description

technical field [0001] The invention belongs to a method for manufacturing bow limbs, in particular to a method for preparing bow limbs for crossbows. Background technique [0002] The crossbow is an ancient device launched by catapult force, and it has wood products, plastic products and metal products. Nowadays, more metals are generally used, and the preparation methods include stamping forming or manual grinding. It is also prepared from plastics, but all have the following disadvantages: the manufacturing process is complicated, and the process conditions are difficult to control. Contents of the invention [0003] The purpose of the present invention is to provide a method for manufacturing bow limbs for crossbows with simple process and low cost. [0004] The technical solution of the present invention is: a method for manufacturing bow limbs for crossbows, comprising the following steps: A. impregnating 50-70 parts of fibers with 90-110 parts of matrix resin in p...
