Embodiment Construction

[0027] Choose 48K T700 untwisted yarn, T700 is a type of carbon fiber, 48K means that a bundle of yarn contains 48,000 carbon fiber monofilaments, such as figure 1 In 101, after the yarn 101 passes through the yarn splitting and flattening device 102, a flat small tow carbon fiber yarn 103 is obtained, and the number of carbon fiber monofilaments contained in a bundle of yarns in the yarn 103 is less than 100. The yarn splitting and flattening equipment 102 is a commercial general equipment, which can be purchased from the market or customized by relevant manufacturers. The quantity of the yarn 101 is related to the production capacity and the specification of the product. In this embodiment, three strands of the yarn 101 are selected. During specific production according to the method of the present invention, the quantity of yarn 101 can be determined according to actual needs.

[0028] The yarn 103 enters the ultrasonic activation pool 104, the carbon fiber activator solut...

Abstract

The invention provides a method for preparing a carbon fiber reinforced molding compound and belongs to the technical field of industrial raw material manufacturing of composite materials. The methodcomprises the following steps in order: a. sinker dividing and breaking-in of carbon fibers; b. activating treatment of carbon fibers; c. baking of carbon fibers; d. coupling coating coating of driedsmall-tow carbon fibers in an ultrasonic coupling pool; e. secondary baking of carbon fibers; and f. compounding of carbon fibers and resin.

Description

technical field [0001] The invention provides a method for manufacturing a carbon fiber reinforced molding compound, which belongs to the technical field of raw material manufacturing in the composite material industry. Background technique [0002] Composite materials are generally composed of a matrix and a reinforcement phase. The composite materials commonly used in mechanical structures are fiber-reinforced resin-based composite materials. The matrix is ​​various types of resins, and the reinforcement phase is various types of fibers. Before the composite material is cured, the resin is liquid or semi-liquid; after the composite material is cured under a certain temperature and pressure to form a composite product, the resin becomes solid. Molding compound is a form of composite material, which appeared to adapt to the molding process of composite materials. It is formed by mixing reinforcing fibers, resins, thickeners and other additives. The product state of molding c...
