Description

Equipment for manufacturing carbon fiber prepreg material

This creation is about a device for manufacturing carbon fiber prepreg material (Prepreg), especially a material capable of pre-impregnating two or more layers of carbon fiber, in the same orientation, different orientations, or multi-directional stacking, thereby increasing The overall structural strength, toughness, and equipment for manufacturing carbon fiber prepreg materials (Prepreg) with improved tensile strength and tensile modulus.

In the manufacturing process, the carbon fiber prepreg material is formed into a prepreg of a required unit size (g/m2) by a carbon fiber bundle through a coating machine, an impregnation machine, and a press-bonding process, and in detail, it is manufactured. The carbon fiber bundle is formed into a composite fabric having a shape that can be shaped and has a better structural strength. The carbon fiber bundle must first be subjected to a planar uniform sand expansion operation through an extension machine, and then uniformly coated with a resin upper and lower release paper (Resin). Coated Interleaf) through the roller, so that the carbon fiber bundle between the upper and lower release papers is impregnated with the resin, and finally, after cooling or drying, the prepreg material of the required unit size (g/m2) is integrally formed in a single direction of the texture ( Note: The unit specification includes the weight of carbon fiber yarn per square meter and the weight percentage of the resin layer per square meter.

However, the physical and chemical properties of the unidirectional prepreg material made of the single direction grain are good, but the overall structure after forming the prepreg is flawed. As shown in the first figure, it can be clearly seen that The carbon fiber prepreg 5 after the carbon fiber prepreg is produced has a carbon fiber layer 51 and a resin layer 52 impregnated on the outer surface of the carbon fiber layer 51, and upper and lower release layers 53, 54 which are used by the product manufacturer for product molding. When the shape is first cut into the required size, one layer of the release layer 53 (54) is torn open, and is attached to the pre-shaped product model, and then the other layer is peeled off after the completion of the specific shaping process. The layer 54 (53) is sufficient. However, since the resin layer 52 is only impregnated on the upper and lower surfaces of the carbon fiber layer 51, the resin layer 52 cannot be sufficiently impregnated into the interior of the carbon fiber prepreg material 5, in addition to making the overall structure stable, which also makes The internal structure of the carbon fiber prepreg material 5 cannot be reinforced, in other words, the carbon fiber prepreg material 5 is limited to the existing structure, and once a higher structural strength is required, only the same material or different type can be added. The material is used for the purpose, that is, the single-direction prepreg material made of the single direction grain needs to adjust the structural strength of the single direction prepreg substrate according to the mode of the single direction prepreg substrate application, so that the single direction The prepreg substrate has a strength of various requirements such as 100 g/m ² or 160 g/m ² for application in various applications, such as Manufacture of airplanes, cars, bicycle bodies, shells of 3C products, or golf clubs, badminton rackets or tennis rackets. However, in today's products with light and thin design requirements, the conventional carbon fiber prepreg material 5 will be laminated with the same material, not only the overall structure is thickened, but also the manufacturing cost is increased; and if it is combined with different materials (such as metal sheets) Because of the difference in thermal expansion coefficient of different materials, it is easy to cause the bonding surface under the influence of the environment, so that the bonding surface is loosened to affect the bonding strength, and even more, it will cause mutual peeling. In short, it is difficult to meet the requirements of the required application and the thinning of the equipment for manufacturing the carbon fiber prepreg material, which has become a great problem for the related manufacturers in the processing process.
