Method for molding hollow vehicle part, hollow vehicle part and automobile
A method for molding a hollow vehicle part, the hollow vehicle part and an automobile. The method includes: a. preparing an inflatable core mold matching a target vehicle part on a geometrical shape in an inflated state, coating curable thermoplastic resin on the surface of the inflatable core mold in the inflated state, and performing shaping; b. braiding fibers on the surface of the shaped core mold to form at least one braided layer; c. conveying the preform into a curing agent passage, and sequentially passing through a heating section and a coating section; and d. conveying the preform mixed with curing agent into a curing passage for curing and molding, then deflating and taking out the inflatable core mold. The method has a high processing automation degree and can meet large-scale production. The produced hollow vehicle part has good mechanical properties, low cost and remarkable lightweight effect.
