Embodiment Construction
[0023] Such as Figure 1-6 As shown, a carbon fiber bundle expansion device according to an embodiment of the present invention includes a preheating zone 1, a plurality of expansion zones 2, and a finishing zone 3. The preheating zone 1 and the finishing zone 3 are distributed on two of the expansion zone 2. On the side, convex rollers 4 and concave rollers 5 are distributed in the preheating zone 1 and the expansion zone 2 at intervals, and a number of flat rollers 6 are arranged in the finishing zone 3; in the convex rollers 4, concave rollers 5 and flat rollers 6 Both are equipped with heating mechanisms; the left side of the preheating zone 1 and the right side of the finishing zone 3 are respectively provided with a traction roller group 7 and a traction roller group 8; the traction roller group 7 and the traction roller group 8 All are connected to a motor. The convex roller 4, the concave roller 5 and the flat roller 6 are distributed on the same horizontal line. Both ...

Abstract
The invention relates to a carbon fiber bundle expansion device. The carbon fiber bundle expansion device comprises a preheating area, a plurality of expansion areas and an arrangement area, wherein the preheating area and the arrangement area are distributed at two sides of the expansion area, convex rollers and concave rollers are distributed in the preheating area and the expansion area at intervals, a plurality of plain rollers are arranged in the arrangement area, heating mechanisms are arranged inside the convex rollers, the concave rollers and the plain rollers respectively, and a pulling roller set I and a pulling roller set II are arranged at the left side of the preheating area and the right side of the arrangement area respectively and are connected with motors respectively. The carbon fiber bundle expansion device has the beneficial effects that the carbon fiber bundle expansion device has a simple structure and convenience in use and is easy to realize; the carbon fiber bundle can be widened and thinned through continuous expansion of the convex rollers and continuous contraction of the concave rollers; the expanded carbon fiber bundle is wide and thin and is a uniform unidirectional fiber sheet, and the processing process of the carbon fiber bundle cannot cause atmospheric environment pollution.
Description
Technical field [0001] The invention relates to an expansion device of carbon fiber bundles. Background technique [0002] There are many reinforcing fibers in fiber-reinforced composite materials, such as carbon fiber, glass fiber, aramid fiber, and matrix resin. For example, the combination of epoxy resin in matrix resin has been developed. For such reinforcing fiber, due to the laminated fiber sheet The thin spreaders are arranged in one direction and can be used in multiple directions, so high-strength and reliable composite molded products can be obtained. In addition, it can be recycled and has a short molding time. Thermoplastic resins for molding, such as nylon 6 resin, polyetherimide resin, and polyetheretherketone resin, are mainly used in aerospace. [0003] Recently, a carbon fiber composite material has attracted attention in the application of aircraft and vehicles. There are various types of carbon fiber, including one called general-purpose carbon fiber with a te...
