Embodiment 1

[0037] The first step is to clean the mold with alcohol; the second step is to apply a layer of release agent in the mold and then apply a layer of gel coat; the third step is to lay carbon fiber cloth in the mold and stick it along the edge of the mold Double-sided adhesive tape, and then arrange the winding tube for vacuuming; the fourth step, lay the release cloth and the diversion net on the carbon fiber cloth that has been laid; the fifth step, lay the vacuum bag film and glue it to the edge of the mold Paste and seal, and vacuumize; the sixth step is to introduce the resin into the mold cavity through the guide tube; the seventh step is to heat or cure the product in the mold at room temperature; the eighth step is to peel off the vacuum bag material, and the product is demoulded. The desired product is obtained; wherein, the mass percentages of the carbon fiber cloth and the resin are 30% and 70% respectively.

Embodiment 2

[0039] The first step is to clean the mold with alcohol; the second step is to apply a layer of release agent in the mold and then apply a layer of gel coat; the third step is to lay carbon fiber cloth in the mold and stick it along the edge of the mold Double-sided adhesive tape, and then arrange the winding tube for vacuuming; the fourth step, lay the release cloth and the diversion net on the carbon fiber cloth that has been laid; the fifth step, lay the vacuum bag film and glue it to the edge of the mold Paste and seal, and vacuumize; the sixth step is to introduce the resin into the mold cavity through the guide tube; the seventh step is to heat or cure the product in the mold at room temperature; the eighth step is to peel off the vacuum bag material, and the product is demoulded. The desired product is obtained; wherein, the mass percentages of the carbon fiber cloth and the resin are 40% and 60% respectively.

Embodiment 3

[0041] The first step is to clean the mold with acetone; the second step is to apply a layer of release agent in the mold and then apply a layer of gel coat; the third step is to lay carbon fiber cloth in the mold and stick it along the edge of the mold Double-sided adhesive tape, and then arrange the winding tube for vacuuming; the fourth step, lay the release cloth and the diversion net on the carbon fiber cloth that has been laid; the fifth step, lay the vacuum bag film and glue it to the edge of the mold Paste and seal, and vacuumize; the sixth step is to introduce the resin into the mold cavity through the guide tube; the seventh step is to heat or cure the product in the mold at room temperature; the eighth step is to peel off the vacuum bag material, and the product is demoulded. The desired product is obtained; wherein, the mass percentages of the carbon fiber cloth and the resin are 35% and 65% respectively.

Abstract

The invention provides an automobile body part and a production method thereof. The invention has the technical scheme that: the automobile body part is made from a composite carbon fiber material, wherein the composite carbon fiber material comprises the following components in percentage by mass: 30-40% of carbon fiber and 60-70% of resin. The production method of the automobile body part comprises the following steps of: cleaning a mould with a cleaning agent; coating a layer of demoulding agent inside the mould and then coating a layer of gel coat; spreading carbon fiber cloth in the mould; spreading demoulding cloth and a diversion net on the spread carbon fiber cloth; spreading a vacuum bag film and sticking with the edge of the mould and sealing, and vacuumizing; leading the resin into a mould cavity through a diversion pipe; heating the product in the mould or curing at a normal temperature; stripping off the vacuum bag material, and demoulding the product. Through the processing method provided by the invention, the body part made from the composite material with excellent properties is prepared, and the automobile body part can maintain the anti-collision performance while reducing the body mass.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to an automobile body part and a production method thereof. Background technique [0002] With the rapid development of automobile technology, more and more new materials and new processes are used in automobiles, which makes people's requirements for light weight, low cost, intelligence, high economy and reliability of automobiles possible. Therefore, the development of material technology plays an important role in the progress of the automobile industry. Because the existing automobile body parts, such as the engine cover, are mostly made of metal steel plates, this material is not only dense, but also more harmful to people when a collision occurs. Contents of the invention [0003] The main object of the present invention is to provide a light weight and high safety automobile body part. [0004] In order to achieve the purpose of the above invention, the technical solution adopt...
