Embodiment 1

[0038] use as image 3 The shown pin mold 7 realizes winding at a small angle through the hooking of the pins on the prepreg yarn 6 . After the winding is completed, the carbon fiber composite transmission shaft tube is surface treated with a silicone film or a PET film. After the curing is completed, cut a length near the inner side of the pin, such as 100mm-200mm, to obtain the carbon fiber / epoxy prepreg yarn 6 transmission shaft tube.

Embodiment 2

[0040] use as Figure 4 The shown head mold 8 achieves small-angle winding through the head. After the winding is completed, the carbon fiber composite transmission shaft tube is surface treated with a silicone film or a PET film. After the curing is completed, the head part is cut, and then demolded to obtain the carbon fiber / epoxy prepreg yarn 6 transmission shaft tube.

Abstract

The invention provides a dry-method winding formation method for a carbon fiber composite transmission axle tube. Pollutants on a mould are cleaned up through acetone, and the mould is heated after the whole mould is evenly coated with release agents; prepreg of a proper width is wound on the mould according to a certain line form at a proper winding speed under proper winding tension, so that a composite layer is formed; heating is stopped, and after the mould is cooled to a certain temperature, a layer of silica film or polythylene terephthalate (PET) film is wound on the surface of the composite layer; after surface treatment is finished, temperature rises to 180 DEG C at the temperature rising speed not higher than 3 DEG C / min and is kept for a period of time, and finally the mould is cooled to the room temperature, released and cut, so that the transmission axle tube is obtained. The carbon fiber or epoxy composite transmission axle tube manufactured through dry-method winding formation method has high specific strength and specific stiffness and good humidity resistance, the thermogravimetric analysis (Tg) is 220 DEG C, and good compactness, uniformity and size accuracy are also realized.

Description

technical field [0001] The invention relates to a carbon fiber composite transmission shaft tube dry winding forming method. Background technique [0002] With the application of composite transmission shafts in vehicles, ships, aerospace and other fields more and more widely, its manufacturing methods are attracting more and more attention. At present, the common methods for making composite transmission shaft tubes include pultrusion, table-rolling, stretch winding, RTM molding and winding molding, among which winding molding is the most widely used. Regardless of its production cost, degree of automation, or the flexibility of its products, including changes in size and layup angles, winding molding is the best choice for making composite transmission shaft tubes. [0003] There are mainly two types of winding molding: wet molding and dry molding. When wet molding products, there are disadvantages such as poor working environment, serious waste of resin, and abrasion of ...
