PROCEDE D'ELABORATION D'UNE STRUCTURE ALLEGEE EN SIC, DU TYPE SANDWICH A AME EN NID D'ABEILLES ET STRUCTURE AINSI OBTENUE

摘要

A light support structure is made by cutting a fibre-reinforced organic honeycomb matrix into the required shape before pyrolysing it to produce a carbon matrix. This is then made into SiC by siliciding the matrix followed by coating with SiC using a vapour technique to reinforce the matrix. Finally a felt-like cloth layer is used to seal both ends of the honeycomb matrix.
