Arcjet testing and analysis of a three-dimensional (3D) woven carbon fabric has shown that it can be used as a thermal protection system and as a load bearing structural component for a low ballistic coefficient hypersonic decelerator called ADEPT (Adaptive Deployable Entry and Placement Technology). Results of arcjet tests proved that the3D woven carbon fabric can withstand flight-like heating while under flight-like biaxial mechanical loads representative of those encountered during shallow entry flight path angles into the atmosphere of Venus. Importantly, the arcjet test results have been used to extend a preliminary material thermal response model based on previous testing of the same 3D woven carbon fabric under uni-axial mechanical loading. Nomenclature B' C = Outgoing mass flux of carbon divided by incoming free stream mass flux, dimensionless C H = Convective heating film coefficient, kg/m 2 s RA = Recession augmentation factor, dimensionless Sdot = Recession rate, m/s q c = Convective heat flux, W/m 2  = Carbon cloth density, kg/m 3
