Abstract

A core member for a sandwich panel and a method of forming the core member for the sandwich panel which are capable of attaining a desired profile, a desired pattern on their surfaces, and a desired inner structure in accordance with an application of the sandwich panel. There is provided a thermoplastic resin core member interposed between two resin skin sheets comprising a closed hollow portion located to be inside of a desired position in accordance with an application of the sandwiched panel, and it is formed by clamping parison of a molten thermoplastic resin positioned to be between two split molds so as to exhibit a desired profile and/or a surface shape, two surfaces against each of which the molten parison is pressed to form an adhesive surface on which the corresponding resin skin sheet is formed.
