Embodiment 1

[0029] Clean the surface of the mold and wipe off the water. The removal of grease and water on the surface of the mold can ensure that the resin will not stick to the mold after curing;

[0030] Cut the carbon fiber woven cloth into strips, the shape and size of the strips match the shape of the mold;

[0031] Mix the curing agent component and the epoxy resin component in the cured epoxy resin E61 in a weight ratio of 20:100, and stir for 3 minutes with a hand-held electric mixer;

[0032] Spread the mixed resin evenly on the surface of the mold, paste the carbon fiber cloth, scrape it gently with a scraper, then apply a layer of resin, and then paste a layer of carbon fiber cloth, repeat the operation until the thickness of the profile reaches 4cm, after the carbon fiber is pasted The total weight ratio of woven cloth and cured epoxy resin is 2.3:1;

[0033] Put the mold in a vacuum bag to evacuate, and cure for 24 hours under vacuum at room temperature;

[0034] After de...

Abstract

The invention discloses a new carbon fiber composite section, which comprises carbon fiber woven cloth and cured epoxy resin according to 2-3:1 of weight ratio thereof. The invention also discloses a manufacturing process of the new carbon fiber composite sections. The invention provides the carbon fiber composite sections used in aviation and special industries, which has high electromagnetic wave screening function. The material not only has light weight, small deformation, but also has good ageing-resistant, resistance to ultra violet radiation, resistance to temperature heat and aging and resistance to chemical attack performances, and has the advantages of high strength ratio and structural strength, small proportion and the like. The preparation method can be easily implemented and can meet the production requirements of large-sized sections.

Description

technical field [0001] The invention relates to a novel composite material, in particular to a novel carbon fiber composite profile and a manufacturing method thereof. Background technique [0002] Material science plays a very important role in the history of human development. The emergence of a new material often leads to the innovation of production tools and a substantial increase in productivity. Therefore, people often use the name of the material as a sign of the development stage of human history, such as the Stone Age, Bronze Age and Iron Age. [0003] Since the 20th century, the development of the highly mature steel industry and other alloy materials has become an important pillar of modern industry. In particular, the emergence of steel and special alloys has finally made machines that could not be made with other materials finally successful. For example, the mechanics of steam turbines have been known for a long time, but have not been realized due to lack o...
