Embodiment Construction

[0020] The present invention will be described below in conjunction with the accompanying drawings and embodiments.

[0021] (1) Preparation of filler mixture: firstly mix 1.42g of filler (including: vulcanization active agent zinc oxide 0.5g, stearic acid 0.1g; antioxidant RD (polytrimethyldihydroquinoline) and 4010NA (N-iso Propyl-N`-phenyl-p-phenylenediamine) each 0.2g; vulcanizing agent DCP (dicumyl peroxide) 0.05g, sulfur 0.16g; accelerator CZ (N-cyclohexyl-2-benzothiazole sulfenamide) 0.16g, TMTD (tetramethylthiuram disulfide) 0.05g) were mixed, crushed, milled, and sieved to about 100 mesh to obtain filler mixed powder. Then it was immersed in 60mL of a mixed solvent of ethyl acetate and cyclohexanone (the volume ratio of the two was 2:3), and ultrasonically dispersed for 30min to obtain a filler mixture.

[0022] (2) Preparation of nitrile rubber raw rubber mixture: weigh 10g of powdered nitrile rubber raw rubber, place it in a 250mL beaker, measure the mixed solvent ...

Abstract

The invention provides a surface rubber coating modification method of plane-woven carbon fibres. The surface rubber coating modification method comprises the following steps: preparation of filler mixed powder; preparation of filler mixed solution; preparation of nitrile rubber-crude rubber mixed solution; preparation of a nitrile rubber mixed rubber cement: stirring the nitrile rubber-crude rubber mixed solution obtained by dissolution at first, and then pouring the filler mixed solution; then sequentially adding plasticizers DOA and DOS to obtain the yellow and sticky nitrile rubber-crude rubber mixed solution; preparation of rubber coating carbon fibre fabric. The method disclosed by the invention realizes the interfacial modification of the plane-woven carbon fibres through the treatment of the plane-woven carbon fibres, and the preparation and the coating of the rubber cement, and then the method can be used for manufacturing a plane-woven carbon fibre reinforced composite material.

Description

technical field [0001] The invention belongs to the field of composite materials, and relates to a method for surface rubber coating modification of plane braided carbon fibers. Background technique [0002] Planar fabric has a long history as a textile. Woven composite materials not only have superior properties such as high specific strength, high specific stiffness and light weight, but also have a wide range of applications, involving almost all walks of life. Since its development at the end of the 20th century, it has been widely used in aerospace, transportation, construction, sports, medical and other fields. [0003] Although many scholars have done research on fiber fabric composites, the research on its dynamic performance mainly focuses on impact, fatigue and damage tolerance, while there are fewer studies on vibration and damping. In other engineering fields, the vibration damping properties of braided composites are particularly critical. For the research on ...
