For more than a decade, ONERA has been actively involved in several programs to develop such materials for different applications (hypersonic flights, propulsion systems &#8230;). In our laboratories, monolithic and composite materials have been investigated as well as several processing methods. In this paper, we present for example the ZrB2-SiC and HfB2-SiC compositions with TaSi2 or Y2O3 additions which have been especially studied in the European Projects ATLLAS and ATLLAS 2. Assessments of several prototypes in realistic environment are also described. Furthermore, based on these material developments, a specific study on the oxidation behaviour of such monoliths from 1200\u00b0C to 2400\u00b0C with a dedicated test bench using a 2 kW CO2 laser has been carried out (oxidation under air and water vapour atmospheres). Recently, some work on the manufacturing of Ultra-High Temperature Ceramic Matrix Composites (UHTCMC) has been initiated using slurry infiltration and pyrolysis. The behaviour and properties of these materials are encouraging.<\/p>\n\n\n\n<p><\/p>\n\n\n\n<p><a href=\"https:\/\/link.springer.com\/article\/10.1007\/s13272-020-00445-y\" data-type=\"link\" data-id=\"https:\/\/link.springer.com\/article\/10.1007\/s13272-020-00445-y\">Read the full paper at the Springer website &gt;<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>Jean-Fran\u00e7ois Justin , Aur\u00e9lie Julian-Jankowiak\u00a0 , Vincent Gu\u00e9rineau\u00a0 , Virginie Mathivet\u00a0 , Antoine Debarre<\/b><\/p>\n<p>DOI Number XXX-YYY-ZZZ<br \/>\nConference Number HiSST 2018_28601101<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[233,229,994,999,394,236,1003],"tags":[595,434,863,862,861],"class_list":["post-13515","post","type-post","status-publish","format-standard","hentry","category-advanced-airframe-materials","category-aircraft-design","category-hisst-2018","category-materials-and-structures-hisst-2018","category-structural-design-materials","category-supersonic-and-hypersonic-aircraft-design","category-thermal-and-energy-management-systems","tag-cmc","tag-hisst-2018","tag-injectors","tag-leading-edges","tag-ultra-high-temperature-ceramics","category-233","category-229","category-994","category-999","category-394","category-236","category-1003","description-off"],"_links":{"self":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/13515","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/comments?post=13515"}],"version-history":[{"count":4,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/13515\/revisions"}],"predecessor-version":[{"id":16603,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/13515\/revisions\/16603"}],"wp:attachment":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/media?parent=13515"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/categories?post=13515"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/tags?post=13515"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
