Title:

EPOXY RESIN COMPOSITION, PREPREG, AND ROLL MADE OF RESIN REINFORCED WITH REINFORCING FIBERS

Document Type and Number:

WIPO Patent Application WO/2000/039188

Kind Code:

A1

Abstract:

An epoxy resin composition giving a cured resin plate which, after 60-hour standing at 150°C and at the saturated vapor pressure, has a water absorption of 3.5 wt.% or lower; a prepreg which comprises the epoxy resin composition and reinforcing fibers; and a fiber-reinforced resin roll which is 1.) a laminate comprising fiber-reinforced resin layers each comprising reinforcing fibers and a matrix resin, wherein the matrix resin is a resin composition giving a cured resin plate which, after 60-hour standing at 150°C and at the saturated vapor pressure, has a water absorption of 3.5 wt.% or lower or 2.) a laminate comprising (i) at least one fiber-reinforced resin layer comprising long reinforcing fibers having a modulus in tension of 600 to 800 GPa and a resin composition and (ii) at least one fiber-reinforced resin layer comprising long reinforcing fibers having a modulus in tension of 140 to 300 GPa and a resin composition.
