Embodiment 1-19

[0151] The amounts of the various components used in each example are listed in Tables 1-4. The epoxy resin compositions shown in Tables 1-4 were prepared according to the method described in (1). The properties of each example are listed in Tables 1-4. These properties were achieved using the curing configuration described in (2).

[0152] A prepreg including reinforcing fibers impregnated with an epoxy resin composition was obtained by the following method. The epoxy resin composition obtained by method (1) was coated on release paper using a knife coater to prepare two sheets of 68.0 g / m2 resin film. Next, two sheets of the prepared above-mentioned resin films were laminated at a density of 1.8 g / cm 2 Both sides of the plain carbon fiber (T700S-12K-50C) in the form of a sheet are impregnated with an epoxy resin composition using a roller temperature of 100°C and a roller pressure of 0.07MPa to prepare a carbon fiber with a weight per unit area of ​​190g / m 2 , a fabric p...

Abstract

The embodiments herein relate to an epoxy resin composition comprising a specific type of amine-based epoxy resin containing four epoxy groups per molecule, a prepreg, and a fiber-reinforced compositematerial. More specifically, the embodiments herein relate to an epoxy resin composition containing a combination of particular types of epoxy resin and curatives that provides high flexural modulusthat is suitable for preparing a fiber-reinforced composite material capable of withstanding extreme use environments such as low-temperature environments and high-temperature moisture- absorbing environments. In addition, the embodiments herein relate to epoxy resin systems capable of achieving a high degree of cure (e.g., 85% or more) within a relatively short period of time (e.g., less than twohours) at a relatively low temperature (e.g., 132 DEG C).

Description

[0001] Cross References to Related Applications [0002] This application claims priority to U.S. Provisional Application No. 62 / 380,033, filed August 26, 2016, and U.S. Provisional Application No. 62 / 539,101, filed July 31, 2017, the disclosures of which are hereby incorporated by reference for all purposes In this article. field of invention [0003] The present application provides an epoxy resin composition for fiber reinforced composite materials which is very suitable for aerospace applications, sports applications and general industrial applications. Background technique [0004] Fiber-reinforced plastic (FRP) materials comprising reinforcing fibers and a matrix resin have excellent mechanical properties such as strength and rigidity while being light in weight, and thus are widely used as aircraft parts, aerospace parts, automobile parts, railroad vehicle parts, ship parts, sports Cases for device components and computer components such as notebook computers. FRP ...
