Abstract: Provided is a molding system for molding a thermoplastic article. The molding system comprises a first mold half and a second mold half. The first and second mold halves together define a plurality of molding cavities in a first closed position. The plurality of cavities serve to mold a corresponding plurality of article components in a first molding stage. Subsequent the first molding stage, the first mold half is displaceable relative to the second mold half to align the plurality of article components formed during the first molding stage. During a second molding stage, the first and second mold halves are closed to a second closed position, to engage and bond together the plurality of article components into a finished thermoplastic article.

Abstract: A composite panel includes a first skin layer, an intermediate structural core, and a second skin layer. The first and second skin layers are disposed on opposing sides of the intermediate structural core. The intermediate structural core provides a geometric array of structural members, the arrangement of which is defined using topology optimization.
