Effect of the Fiber Orientation Relatively to the Plasma Flow Direction in the Ablation Process of a Carbon-Phenolic Composite

Autor: Sonia Fonseca Costa e Silva, Humberto Araujo Machado, Edison Bittencourt

Publikováno v: Journal of Aerospace Technology and Management, Vol 7, Iss 1 (2015)

Composite materials are vastly employed in rocket nozzle extensions and as thermal protection shields in aerospace industry. In both cases, ablative and thermal properties play an important role for material choice and equipment sizing. These propert
