Abstract
A high performance resin matrix for resin transfer moulding(RTM) was prepared by applying low viscosity anhydride to cure epoxy resin.The results showed that the viscosity of the resin was only 0.11 Pa·s at 25℃,the pot-life was more than 24 hr at 25℃.The glass transition temperature was 160℃.The tensile strength,tensile module,flexural strength and flexural module of the carbon composite laminate were 860 MPa,70.0 GPa,820 MPa and 61.5 GPa respectively.It was therefore concluded that the characteristic of matrix resin was low viscosity,long pot-life and high glass transition temperature.The cured resin and composites had excellent mechanical properties.The high performance matrix resin could meet the requirements of RTM.
