Title:
POROUS SANDWICH STRUCTURE AND INTEGRATED MOLDED BODY USING SAME
Document Type and Number:
WIPO Patent Application WO/2024/095814
Kind Code:
A1
Abstract:
A porous sandwich structure according to the present invention comprises: a core layer that is formed by binding three-dimensionally arranged discontinuous reinforcing fibers in a thermoplastic resin; and skin layers that are provided on respective sides of the core layer and include continuous reinforcing fibers and a matrix resin. The porous sandwich structure is characterized in that the thermoplastic resin as spread flat in regions of the core layer that are surrounded by a plurality of discontinuous reinforcing fibers has a plurality of holes, and the porosity of the core layer is at least 50 vol% but no more than 76 vol%. An integrated molded body according to the present invention uses the porous sandwich structure. The present invention provides a porous sandwich structure and an integrated molded body that allow for integration of a porous sandwich structure that has a specific internal structure and a structure that is separate from the porous sandwich structure to achieve lightweightness, high bonding strength with the separate member, and greater thinness for recent structures that require thinness and complex shapes.
