EPOXY RESIN COMPOSITION, FIRER-REINFORCED COMPOSITE MATERIAL, AND METHOD FOR PRODUCING FIRER-REINFORCED COMPOSITE MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide an epoxy resin composition which has excellent productivity and heat resistance, to provide a firer-reinforced composite material, and to provide a method for producing the same.;SOLUTION: This epoxy resin composition is characterized by satisfying the following expressions (1) to (4) at a curing temperature Tc included in a range of 60 to 180°C. (1) 1≤t₁₀≤10, (2) 3≤t₉₀≤30, (3) 1≤t₉₀/t₁₀≤3, (4) Tg≥Tc+20, wherein t₁₀ : a time (minute) from a measurement-starting time to a time reaching a cure index of 10%, on a dielectric measurement at a curing temperature Tc; t₉₀: a time (minute) from a measurement-starting time to a time reaching a cure index of 90%, on a dielectric measurement at a curing temperature Tc; Tg: the glass transition temperature (°C) of an epoxy resin composition at the passage point of t₉₀ (minute).;COPYRIGHT: (C)2006,JPO&NCIPI
