Title: DEVELOPMENT OF FAST-CURING EPOXY RESIN WITH HIGH HEAT RESISTANCE 

 

Abstract: To date, fast-curing epoxy resins with heat resistance of up to 180 °C have not been reported and thus, mass production of CFRP that can endure in a high heat environment has not progressed.  Therefore, in this study, we developed a fast cure epoxy matrix resin for CFRP, which has both high heat resistance and good adhesion to carbon fiber (TE 210). 
 
Carbon fiber prepreg (T700, 12K) were prepared using the developed epoxy resin TE 210 as a matrix, and CFRP specimen were produced by press molding at 180°C and 0.3 MPa.  Various mechanical property tests (tensile, flexural, compression, ILSS) were preformed in the CFRP specimen, and the physical properties were compared with conventional high heat resistant CFRP.  The specimen made with TE 210 were shown to have equivalent physical properties as the conventional high heat resistance CFRP, and the resin was proven to have sufficient performance for application as a matrix resin for carbon fiber prepreg.  In fact, we succeeded in molding three-dimensional CFRP structures from a prepreg made with the new TE 210 matrix resin by press molding at 180°C for 5 min. 
 
Because TE 210 has high heat resistance and fast cure properties, the resin is expected to find applications in mass production of CFRP products with high heat resistance.
