Problems solved by technology

[0003] The fiber direction of regular carbon fiber / glass fiber yarn sheet is distributed in the same direction, and the performance is anisotropic. In some fields, fiber yarn sheets with anisotropic distribution of fiber direction and isotropic performance are required. Fiber yarn sheets with anisotropic distribution and isotropic properties are arranged with fibers with a single fiber direction at an angle (as shown in Figure 1). Not only is the production process cumbersome, but the regular carbon fiber / glass fiber composite The film is expensive and the cost is high
[0004] On the other hand, in the existing production process of carbon fiber / glass fiber composite materials, the leftovers produced by cutting are difficult to deal with, and are directly discarded as waste, which not only causes a great waste of materials, but also becomes an environmental killer that pollutes the environment

Embodiment 1

[0035] Take 1 kg of carbon fiber composite material leftovers, paste all the leftovers together by hand, then cut the material into 2cm×2cm small squares with a yarn cutting machine, add epoxy resin at a weight ratio of 1:2, mix evenly and let it stand for 1 After hours, the material was poured into the kneader and kneaded for 2 hours. Take out the kneaded material, bake it at 50°C for 10 minutes, and finally press the tablet with a hydraulic press, and the thickness of the tablet is about 4mm.

[0036] Take several new carbon fiber composite sheets with the above-mentioned pressed fiber directions randomly dispersed and press them together to form a different-directional fiber layer; then take a number of ordinary carbon fiber or glass fiber yarn sheets with the fiber directions in the same direction and regular distribution Zhang, staggered (makes the fiber direction of each sheet to be at a certain angle) and pressed into the same direction fiber layer, and then laminate the di...

Embodiment 2

[0039] Take 1 kg of glass fiber composite material leftovers, paste all the leftovers together manually, then cut the material into 2cm×2cm small squares with a yarn cutter, add epoxy resin according to the weight ratio of 1:2, stir evenly and then stand still For 1 hour, the material was poured into the kneader and kneaded for 2 hours. Take out the kneaded material, bake it at 50°C for 10 minutes, and finally press the tablet with a hydraulic press, and the thickness of the tablet is about 4mm.

[0040] Take several new glass fiber composite sheets with the above pressed fiber directions randomly dispersed and press them together to form a different-directional fiber layer; then take ordinary glass fiber or carbon fiber yarn sheets with the fiber directions in the same direction and regular distribution Several sheets, staggered (makes the fiber direction of each sheet at a certain angle) are pressed into the same direction fiber layer, and then the different direction fiber laye...

Abstract

The invention relates to the carbon fiber compound material technique, particularly carbon fiber compound material sheet clippings in the processing. The leftovers are recycled by making into fiber directional random distributed new carbon fiber compound material. It sticks the leftovers into mixture, cutting the mixtures into small blocks, dipping the mixture into the resin, blending evenly for a while, distracting carbon fiber inversion for dipped mixture, selecting the pinched material to dry for a while, picking out a portion of dried material to compress to get the compound material.

Description

Technical field: [0001] The invention relates to the technical field of carbon fiber / glass fiber composite materials, in particular to the application, application method and products of waste scraps during the production process of carbon fiber / glass fiber composite materials. Background technique: [0002] With the rapid development of materials technology, a new kind of low density composite materials such as carbon fiber and glass fiber have appeared one after another. After curing, the carbon fiber / glass fiber composite material can obtain high strength. It can not only be used as a protective material to cover the surface of the object, but also can be used in many fields instead of a single metal material as a whole, such as in manufacturing. In the field of pipe fittings, shells and other profiles. In the existing process of using carbon fiber composite materials to manufacture pipe fittings, shells, etc., the regular carbon fiber / glass fiber composite materials are gener...
