ABSTRACT	Materials suitable for the thermal protection system(TPS)of the rocket fairing for the Japanese next generation lauch vehicle named H-II were tested using an arc-heated wind tunnel.The main constituents of the candidate materials were epoxy resin and silicon rubber.The heating rate was from 60～100kW/m2 in accordance with the maximum heating rate of the nose region of an ascending H-II rocket.Test results showed that polycondensed silicon rubber was the best candidate as the main component of the TPS,and also that a SiC coating was indispensable.In addition,based on results and a preliminary estimation of the skin temperatures of the fairing nose region,a SiC coating of about 2 mm in thickness is considered sufficient to achieve thermal protection capability.
