Resin composition, cured material, resin film, and resin composite sheet

Abstract

This invention provides a resin composition, a cured product, a resin film, and a resin composite sheet. The disclosed resin composition comprises a thermosetting resin containing a maleimide compound and a thermoplastic elastomer. A dumbbell-shaped test piece of pattern 6 with a thickness of 0.1 mm, formed by molding the thermoplastic elastomer at 200°C and 3 MPa, exhibits an elongation at break of ≥200% as measured according to JIS K 6251 at a tensile speed of 5 mm / min. Furthermore, the elongation at break after heating the test piece at 150°C for 3 hours also exhibits an elongation of ≥200%, and the composition does not contain a free radical polymerization initiator.
