The wet-winding process for carbon fiber reinforced composites, the properties and service life of the resin matrix are studied. The mechanical properties of the casts for two resin formula, i.e. HT11A and HT11B, are excellent. The results show that tensile strength and modulus reach over 100MPa and 3.9GPa respectively. The formulae have a good heat-resistance performance and the service life exceed 9h, meeting the demand for wet-winding processes. Their PV/W values of Φ150mm pressure vessels wound with the carbon fiber reinforced composite are all over 34km and their translation ratio (K) of carbon fiber strength is up to 82%.
