This invention relates to an
impact-resistant
structural component, an automobile, and a method for manufacturing the
impact-resistant
structural component, belonging to the technical field of automotive structural components. The
impact-resistant
structural component comprises, from top to bottom: a
surface layer, an impact-resistant layer, and a bottom layer; the
surface layer is a plastic matrix material; the impact-resistant layer includes a composite
fiber material, which includes an anchoring portion and a filling portion in the thickness direction. The composite fibers in the anchoring portion are embedded in the plastic matrix material of the
surface layer, anchoring the composite
fiber material within the plastic matrix material and bonding it to the surface layer; the
fiber gaps in the filling portion are filled with a shear thickener; the bottom layer is an injection-molded material layer, surrounding the bottom and sides of the impact-resistant layer, and directly contacting and fusing with the surface layer around the perimeter of the impact-resistant layer. This invention uses
hot pressing and injection molding to form the impact-resistant structural component containing shear thickener, eliminating the need for pre-preparing a cavity structure to accommodate the shear thickener using mechanical methods. The structure is simple, the product has fewer parts, and is lightweight. Compared to the technique of filling a pre-prepared cavity with shear thickening fluid and then sealing the cavity, this method can significantly reduce the thickness of the product and provides greater design flexibility.
