Abstract
Provided is a method of manufacturing a carbon fiber sheet molding compound, the method including: performing sizing treatment on a carbon fiber using a sizing agent; cutting the sizing-treated carbon fiber into pieces; spraying the pieces of carbon fiber onto a first resin coated on a surface of a first carrier sheet; and uniting together a second resin coated on a second carrier sheet and a surface of the first resin, wherein the sizing agent, the first resin, and the second resin include the same compounds.
Claims6
A method of manufacturing a carbon fiber sheet molding compound, the method comprising:
- performing sizing treatment on a carbon fiber using a sizing agent;
- cutting the sizing-treated carbon fiber into pieces;
- spraying the pieces of carbon fiber onto a first resin coated on a surface of a first carrier sheet;
- and
- uniting together a second resin coated on a second carrier sheet and a surface of the first resin,
- wherein the sizing agent, the first resin, and the second resin include the same compounds, and
- wherein the sizing treatment is performed in such a state in which the carbon fiber is spread to be 1.2 to 5 times as wide as an original width thereof.
An apparatus for manufacturing a carbon fiber sheet molding compound, the apparatus comprising:
- a fiber pretreatment portion which performs sizing-treatment on a carbon fiber;
- and
- a sheet manufacturing portion which manufactures a sheet using the carbon fiber pretreated by the fiber pretreatment portion,
- wherein the fiber pretreatment portion sequentially includes a fiber roll to supply the carbon fiber, a storage tank containing a sizing agent, and a cutting device to cut the carbon fiber,
- the sheet manufacturing portion includes a sheet roll to supply a carrier sheet and a resin coating portion containing a resin to be coated on a surface of the carrier sheet, and
- the sizing agent and the resin include the same compound, and
- wherein the storage tank includes a plurality of rollers and the plurality of rollers are arranged alternately vertically one above another in a depth direction of the storage tank.
