In general, the nonwoven fabric is formed in the form of cloth (web, web) by combining the fibers by a chemical or mechanical method without going through the weaving process of the fiber, mainly such as garment wick, filter, carpet, abrasive cloth, sanitary cloth It is used in various fields of industry.

Nonwoven fabrics are manufactured from synthetic fibers and composites containing them in addition to nature because of their good texture.

Among these nonwoven fabrics, attention has recently been focused on nonwoven fabrics using carbon fibers.

Carbon fiber is lighter than metal and has strength, elasticity, heat resistance and impact resistance as well as corrosion resistance, and it does not corrode. Recently, fishing rods, golf clubs, tennis rackets, aircraft, wind turbines, automotive parts, civil engineering and construction materials Widely used.

Since carbon fiber can be applied in various ways through filming or sheeting, it is becoming a focus of attention and research around the world as the material of dream in the future.

Although carbon fiber is normally used as a reinforcing material of a composite material product using a thermosetting resin or a thermoplastic resin as a matrix resin, it is mainly used as a thermosetting resin that is easy to form and handle. That is, when the matrix resin such as vinyl ester resin is impregnated quickly and uniformly 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.
