Description

BACKGROUND OF THE INVENTION 1. Apparatus for manufactuaring carbon fiber non-woven fabric, method for the same and car fiber non-woven fabric produced by them}

In general, non-woven fabrics are formed in the form of fabrics (fabrics, webs) by allowing fibers to be bonded together by chemical or mechanical methods without going through the weaving process of fibers, and are mainly used as wicks for clothes, filters, carpets, polishing cloths, sanitary cloths, etc. It is used in various fields of industry.

Because of its good texture, non-woven fabrics are manufactured with synthetic fibers and composite materials including these synthetic fibers in addition to natural materials.

Among these non-woven fabrics, a non-woven fabric using carbon fiber has recently attracted attention.

Carbon fiber is lighter than metal but has superior strength and elasticity than metal, has good heat resistance, impact resistance, and does not corrode. Recently, fishing rods, golf clubs, tennis rackets, aircraft, wind power generation devices, automobile parts, civil engineering and construction materials It is widely used as such.

Since such carbon fiber can be applied in a wider variety through film formation or sheet formation, it is becoming the subject of interest and research around the world as much as it is a dream material in the future.

Carbon fiber is usually used as a reinforcing material for composite material products in which a thermosetting resin or a thermoplastic resin is used as a matrix resin, but it is mainly used as a thermosetting resin with easy moldability and easy handling. That is, if a matrix resin such as a vinyl ester resin is rapidly and uniformly impregnated between the carbon fibers constituting the carbon fiber bundle, physical properties such as affinity and bending strength of the obtained composite material can be improved.

Korean Patent Publication No. 2014-0126307 relates to a carbon fiber composite material using a thermoplastic resin as a matrix resin for carbon fibers. As in the prior art, since carbon fibers cannot form desired properties by themselves, various matrix resins are combined to produce a carbon fiber nonwoven fabric.

However, as the carbon specific gravity of the carbon fiber decreases as much as the amount of the matrix resin bonding the matrix resin to the carbon fiber, there is a problem that the inherent characteristics of the carbon fiber are deteriorated.

Therefore, in Patent Registration No. 10-1588433 filed and registered by the present applicant, the spacing and angle between each saw blade mounted on a plurality of rolls for carding the carbon fiber raw material are uniformly limited, so that a carbon fiber web in the form of a film is formed only with pure carbon fibers.
