S1904-1-6 超低密度CFRPアブレータの熱化学特性(大気突入・減速技術(1),社会変革を技術で廻す機械工学)

抄録

A carbon fiber reinforced plastic (CFRP) has been widely used as a heat shield material in aerospace community. This CFRP will be pyrolyzed if material surface is heated, and a carbonized layer will be formed. The oxidation of carbonized CFRP in atmosphere was found to be divided into the rate-controlled oxidation region and the diffusion-controlled oxidation region. Okuyama developed a new ultra light-weight CFRP that is called LATS. In order to design a lightweight transfer vehicle, this paper describes the thermochemical characteristics (the mass loss characteristics) of the LATS in the diffusion-controlled oxidation region. The LATS can be applied to a heat shield material for the transfer vehicle by these experiments.
