example 1

[0061] Provide a polyurea ester resin (TPU) of Shore A (Shore A) 65 and a carbon fiber twill fabric with a thickness of 0.28mm and a weight per square meter of 248g, and the polyurea ester resin is heated to 180 ℃ with a hot melt machine to melt, And it is coated on the surface of the carbon fiber twill fabric with a combination of rollers and a doctor blade, and then baked at 205 ° C for 40 seconds through infrared rays, so that the polyurea ester resin infiltrates the fibers of the carbon fiber twill fabric, and then by containing a hardness of Xiao The roller group of the rubber roller with Shore A 65 and the steel roller is heated at 160℃ and pressurized at 16kgf / cm2, so that the thermoplastic resin is fully distributed in the carbon fiber fabric, and the surface presents a three-dimensional texture ; Finally, the carbon fiber twill fabric coated with polyurea ester resin is cooled at 7°C, the production line speed is 2m / min, and the cooling dwells for 30 seconds, so that t...

[0073] The soft carbon fiber composite materials obtained from Examples 1 to 7 can be post-processed and sewn together with the inner lining of the conductive fabric to make products such as handbags, luggage and wallets. The following table 2 compares the general cowhide, the existing glass fiber silver-plated, the conductive fabric provided by the applicant in TW1325907 (copper electroplating on the surface of polyester cloth), the soft carbon fiber composite material obtained in Example 1, and the above conductive fabric (as Inside) and the EMI shielding properties of the soft carbon fiber composite material obtained in Example 1 after sewing. It can be seen from Table 2 that the soft carbon fiber composite material of the present invention has quite good EMI shielding properties, and if the soft carbon fiber composite material of the present invention is combined with the conductive fabric, the shielding effect of the original conductive fabric can be increased, so it can b...

Abstract

The invention relates to a flexible carbon fiber composite material with a stereoscopic grain surface and a manufacturing method of the flexible carbon fiber composite material. The composite material comprises a carbon fiber fabric with a stereoscopic grain surface and thermoplastic resin in the carbon fiber fabric. The method comprises the following steps: providing the thermoplastic resin, and heating to melt the thermoplastic resin; providing the carbon fiber fabric with stereoscopic grains on at least one surface, and at least coating the surface with stereoscopic grains of the carbon fiber fabric with the melted thermoplastic resin; baking the carbon fiber fabric coated with the thermoplastic resin so as to enable the thermoplastic resin to permeate into the carbon fiber fabric; heating, and pressurizing the carbon fiber fabric coated with the thermoplastic resin by virtue of at least one flexible pressurizing device, so as to present the stereoscopic grains in the surface of the thermoplastic resin; and cooling to cure the carbon fiber fabric coated with the thermoplastic resin, so as to obtain the composite material.

Description

technical field [0001] The present invention relates to a soft carbon fiber composite material and a manufacturing method thereof, in particular to a soft carbon fiber composite material with good bonding between carbon fiber fabric and thermoplastic resin and showing three-dimensional lines on the surface. Background technique [0002] Existing methods for shielding electromagnetic interference (EMI) in electronic products are the use of conductive coatings or metallic films or metal-plated fabrics and conductive adhesive films. In recent years, it has been found that carbon fiber itself has the function of shielding EMI, but because the carbon fiber products of traditional carbon fiber composite materials are suitable for hard, rigid and light product characteristics, such as bicycles, automobiles, airplanes or specific military purposes, the current carbon fiber composite materials The material can be made into a soft carbon fiber composite material, so it can be used in ...
