Description

Variable-angle carbon fiber automatic laying system

Technical Field

The invention relates to the technical field of composite material processing, in particular to an automatic variable-angle carbon fiber laying system.

Background

The carbon fiber composite material has the advantages of high specific strength, high specific modulus, fatigue resistance, corrosion resistance and the like, can reduce the weight of a product and improve the performance, and is widely applied to the fields of aerospace, automobiles and ships, wind power generation, medical appliances, sports goods and the like. The automatic laying technology of the carbon fiber composite material has the characteristics of high production efficiency and excellent performance of prepared products, and is widely applied to production and manufacturing of composite material parts. In order to meet the requirements of full paving of the surface of a mold and good mechanical properties of a manufactured component in the automatic laying process of the carbon fiber composite material, a fiber track needs to have a certain steering angle, but the manufacturing defects of buckling of outside fibers and buckling deformation of inside fibers are generated when the steering radius of the carbon fiber composite material is smaller, so that the final manufacturing performance and the design performance of the component are greatly different, and when the existing automatic laying is carried out by adopting 3.175mm wide tows, the obvious local fiber buckling phenomenon can occur when the steering radius is smaller than 635 mm. The turning radius of the carbon fiber composite material seriously restricts the turning radius design of a fiber track and the realization of full paving of the surface of a complex part.

The customized fiber laying is a prefabricated part manufacturing technology based on embroidery, can flexibly position carbon fiber tows, and can realize 90-degree turning and sewing of fibers. However, due to the existence of the sewing thread, the manufacturing equipment has a complex structure, only the sewing of single fiber tows can be carried out, the displacement of the sewing thread and the zigzag stitch can cause the waviness of the fiber, and the induced waviness can cause the reduction of the rigidity and the strength characteristics. British patent GB2492594A discloses a composite steering lay-up method based on shear deformation, which produces in-plane shear deformation during lay-up of carbon fiber composite to reduce the fiber steering radius and increase the fiber steering angle. However, during continuous steering, the thickness along the fiber laying path is not uniform, so that the local thickness of the final part does not meet the design requirement of the part, and meanwhile, due to the limitation of technical characteristics, the increase of the fiber steering angle is limited, and the laying speed is extremely low. 3D prints continuous carbon fiber and adopts single continuous and the little fibre silk bundle of width to print, can realize great fibre and turn to, nevertheless because single fibre silk bundle and width are little make 3D print continuous fiber's manufacturing efficiency extremely low.
