Description

Plastic composite panel and manufacturing method of the same An embodiment of the present invention relates to a plastic composite panel, and more specifically, to a plastic composite panel that is bonded to the body of a Purpose Built Vehicle (PBV) and a method for molding the same. Recently, the automotive industry has been introducing new concepts for future mobility visions aimed at realizing dynamic, human-centered future cities. One such future mobility solution is the Purpose Built Vehicle (PBV) as a form of purpose-based mobility. PBV vehicles are eco-friendly mobility solutions that provide customized services to passengers during their journey from the ground to their destination. Based on electric vehicles (EVs) and utilizing artificial intelligence, they can set optimal routes for specific situations and perform platooning. The body of a PBV vehicle consists of an underbody (also referred to as a rolling chassis or skateboard in the industry) and an upper body mounted on the underbody. Here, the upper body may be constructed of a space frame. In the above, the upper body is equipped with a body frame made of aluminum or steel and a plastic composite panel bonded to the body frame with an adhesive in order to reduce the weight of the vehicle body. Such plastic composite panels are manufactured by forming a plastic composite material into a set shape using a mold. However, conventionally, the folded portions (undercut portions) of the plastic composite panel get caught in the molding section of the mold, making it difficult to smoothly eject the panel from the mold. The matters described in this background technology section are written to enhance understanding of the background of the invention and may include matters that are not prior art already known to those skilled in the art to which this technology belongs. These drawings are for reference to explain exemplary embodiments of the present invention, and therefore, the technical concept of the present invention should not be interpreted as being limited to the attached drawings. FIG. 1 is a drawing illustrating an example of a vehicle body applied to an embodiment of the present invention. FIG. 2 is a cross-sectional view along line AA of FIG. 1 illustrating a plastic composite panel according to an embodiment of the present invention. FIG. 3 is a cross-sectional view along line BB of FIG. 1 illustrating a plastic composite panel according to an embodiment of the present invention. FIGS. 4 to 6 are drawings for explaining a method of molding a plastic composite panel according to an embodiment of the present invention. FIG. 7 is a cross-sectional view along the CC line of FIG. 1 illustrating a plastic composite panel according to another embodiment of the present invention. FIG. 8 is a drawing illustrating a mold for forming a plastic composite panel according to another embodiment of the present invention. FIG. 9 is a cross-sectional view along line DD of FIG. 1 illustrating a plastic composite panel according to another embodiment of the present invention. FIG. 10 is a cross-sectional view along the line EE of FIG. 1 illustrating a plastic composite panel according to another embodiment of the present invention. Hereinafter, embodiments of the present invention are described in detail with reference to the attached drawings so that those skilled in the art can easily implement the present invention. However, the present invention may be embodied in various different forms and is not limited to the embodiments described herein. To clearly explain the present invention, parts unrelated to the explanation have been omitted, and the same reference numerals are used for identical or similar components throughout the specification. The size and thickness of each component shown in the drawings are depicted arbitrarily for the convenience of explanation, and thus the present invention is not necessarily limited to what is shown in the drawings; furthermore, the thickness has been enlarged to clearly represent various parts and regions. Furthermore, in the detailed description below, the designation of components as "1st," "2nd," etc., is intended to distinguish them due to their identical nature, and is not strictly limited to that order in the description below. Throughout the specification, when a part is described as including a certain component, this means that, unless specifically stated otherwise, it does not exclude other components but may include additional components. In addition, terms such as ...part, ...means, etc., as described in the specification refer to a comprehensive unit of composition that performs at least one function or operation. FIG. 1 is a drawing illustrating an example of a vehicle body applied to an embodiment of the present invention. Referring to FIG. 1, a plastic composite panel (100) according to an embodiment of the present invention can be applied, for example, to the body of a purpose-built vehicle (PBV) bas
