Abstract

A series of new epoxy resin base on 1,5-naphthalenediol were prepared to produce the heat-resistant carbon fiber-reinforced composites. The structures of the epoxy resins were characterized by Fourier Transform Infrared (FTIR) spectroscopy and Gel Permeation Chromatography (GPC) analyses. Dynamic curing behavior was investigated using Differential Scanning Calorimetry (DSC). The physical properties of the cured polymers were evaluated with Dynamic Thermal Mechanical Analyses (DMTA) and Thermogravimetric Analyses (TGA). The results showed that the cured polymer exhibited a higher glass transition temperature (Tg) of 251.1°C and better thermal stability. Such properties make the resin highly promising for heat-resistant composite applications.
