Abstract

The invention belongs to the field of composite material molding, and particularly relates to a composite material pipe fiber winding and molding method. The molding method comprises the following steps that a molding material is winded and molded through a supporting tool and a winding device in a segmented manner; curing molding is conducted on a product which is subjected to the winding and molding; and the appearance size of the curing molded product is machined. The segmented winding and molding method is provided for a ultra-long sized fiber winding composite pipe, a multi-point supporting winding mode is adopted, so that the suspension length is reduced, the influence of self weight and tension on deflection deformation of the product is reduced, the rigidity and deflection deformation requirements of the product are guaranteed, the winding molding of the ultra-long body pipe fiber is realized, and the method has very good practicability.

Description

technical field [0001] The invention belongs to the field of composite material molding, and in particular relates to a composite material tube fiber winding molding method. Background technique [0002] With the rapid development of material technology, composite materials are widely used because of their high specific strength, high specific stiffness, excellent vibration damping, fatigue resistance, and corrosion resistance compared with metal materials. [0003] In the prior art, for some composite pipes whose total length exceeds 10 m and has high strength requirements, composite pipe fiber winding is usually used for molding. This type of product has a large self-weight, and the weight of the tooling required in the forming process is also relatively large. As a result, during the winding forming process, affected by the self-weight and winding tension, the formed product has a problem of large deflection and deformation, which directly affects The straightness of the...
