Abstract
Official abstract text for this publication.
The resin composite of the present invention has a polyamide-based resin expanded sheet, and a fiber-reinforced resin layer integrally laminated on a surface of the polyamide-based resin expanded sheet.
First claim
Opening claim text (preview).
What is claimed is: 1. A resin composite comprising: a polyamide-based resin expanded sheet; and a fiber-reinforced resin layer laminated on a surface of said polyamide-based resin expanded sheet, wherein: said fiber-reinforced resin layer and said polyamide-based resin expanded sheet are integrated with each other, said polyamide-based resin expanded sheet is an extrusion-expanded sheet having an average cell diameter of 10 μm or more and 1,000 μm or less, a tensile elongation at break of 80% or more and 150% or less, and a contact angle of 30° or more and 90° or less, said polyamide-based resin expanded sheet comprises a crosslinking agent in an amount of 0.05% by mass or more and 10% by mass or less, and a crystallization degree of the polyamide-based resin contained in the polyamide-based resin expanded sheet is 10% or more. 2. The resin composite according to claim 1 , wherein said polyamide-based resin expanded sheet has a thickness of 0.1 mm or more and 5 mm or less. 3. The resin composite according to claim 1 , wherein said polyamide-based resin expanded sheet has an apparent density of 0.1 g/cm 3 or more and 1.1 g/cm 3 or less. 4. The resin composite according to claim 1 , wherein a content of a reinforcing fiber in said fiber-reinforcing resin layer is 30% by mass or more and 80% by mass or less. 5. The resin composite according to claim 1 , which has an apparent density of 0.3 g/cm 3 or more and 1.5 g/cm 3 or less.
