CORE MATERIAL FOR FIBER REINFORCED COMPOSITE AND FIBER REINFORCED COMPOSITE HAVING THE SAME

摘要

To provide a core material for a fiber reinforced composite having an excellent workability upon being composited with a fiber reinforcing material. A core material for a fiber reinforced composite of the present disclosure comprises a molded product of expanded beads containing a thermoplastic resin, and having a heat shrinkage onset temperature of 80° C. or higher, a linear expansion coefficient of 10×10⁻⁵ mm/mm·° C. or less, and a ratio of change in dimensions with heating at 130° C. of −4.0% to 0%.
