The material 20 has a linear expansion coefficient larger than that of the FRP structure by a predetermined value or more, and has the shape keeping property and the heat resistance to endure the shaping temperature."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Artificial defect material and manufacturing method of FRP structure","description":"In an artificial defect material 10 of an FRP structure, a heat-resistant high-linear-expansion material 20 arranged between the layers thermally expands in case of high-temperature shaping of the FRP","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10518487","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
