We have developed one kind of novel multifunctional ceramic composites which is reinforced with a high volume fraction (60%) of aligned carbon nanotubes (CNTs). Unique material properties are listed as:<\/p>\n<ul>\n<li><b>Material composition: <\/b>60 vol.% of CNT and 40 vol.% of SiCN<\/li>\n<li><b>High surviving temperature<\/b>: up to 1000 Celsius degree<\/li>\n<li><b>Sustainability<\/b> in harsh environment: oxidation, hot-corrosion environment, water vapor and acid fume.<\/li>\n<li><b>Flexibility<\/b>: can be bent to 100% of the original length and the flexibility testing can be repeated for 1000 times without any crack or performance degradation.<\/li>\n<li><b>Low density<\/b>: 2.1 g\u00b7cm-3<\/li>\n<li><b>thermal conductivity <\/b>in room temperature:\n<ul>\n<li>in-plane: 7.2 W\/(m\u00b7K))<\/li>\n<li>through-thickness: 2.0 W\/(m\u00b7K))<\/li>\n<\/ul>\n<\/li>\n<li><b>In-plane electrical conductivity<\/b>: 3.22\u00d710e6 S\/m<\/li>\n<li><b>Tensile strength: <\/b>538 MPa<\/li>\n<li><b>Young\u2019s modulus: <\/b>118 GPa<\/li>\n<\/ul>\n<p>With such unique multifunctional properties, the material can be used for stringent harsh environments, such as liquid-fueled rocket engine combustion devices (thrust chambers and nozzles), aircraft brakes, etc.. It can also be suitable for surface coatings on curved surface on hypersonic vehicles for thermal management.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-550 alignleft\" src=\"https:\/\/mae.ncsu.edu\/cxu\/wp-content\/uploads\/sites\/20\/2019\/06\/Hypersonic-Vehicle-600x450.png\" alt=\"\" width=\"847\" height=\"636\" srcset=\"https:\/\/mae.ncsu.edu\/cxu\/wp-content\/uploads\/sites\/20\/2019\/06\/Hypersonic-Vehicle-600x450.png 600w, https:\/\/mae.ncsu.edu\/cxu\/wp-content\/uploads\/sites\/20\/2019\/06\/Hypersonic-Vehicle.png 720w\" sizes=\"auto, (max-width: 847px) 100vw, 847px\" \/><\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<\/div>\n<\/div>\n<table style=\"border-collapse: collapse;width: 49.2904%\">\n<tbody>\n<tr>\n<td style=\"width: 19.4892%\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-302\" src=\"https:\/\/mae.ncsu.edu\/cxu\/wp-content\/uploads\/sites\/20\/2019\/06\/surface-of-CNT-PDC-6-600x486.png\" alt=\"\" width=\"252\" height=\"204\" srcset=\"https:\/\/mae.ncsu.edu\/cxu\/wp-content\/uploads\/sites\/20\/2019\/06\/surface-of-CNT-PDC-6-600x486.png 600w, https:\/\/mae.ncsu.edu\/cxu\/wp-content\/uploads\/sites\/20\/2019\/06\/surface-of-CNT-PDC-6-768x622.png 768w, https:\/\/mae.ncsu.edu\/cxu\/wp-content\/uploads\/sites\/20\/2019\/06\/surface-of-CNT-PDC-6.png 797w\" sizes=\"auto, (max-width: 252px) 100vw, 252px\" \/><\/td>\n<td style=\"width: 19.802%\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-294\" src=\"https:\/\/mae.ncsu.edu\/cxu\/wp-content\/uploads\/sites\/20\/2019\/06\/surface-of-CNT-PDC-4-600x476.png\" alt=\"\" width=\"260\" height=\"207\" srcset=\"https:\/\/mae.ncsu.edu\/cxu\/wp-content\/uploads\/sites\/20\/2019\/06\/surface-of-CNT-PDC-4-600x476.png 600w, https:\/\/mae.ncsu.edu\/cxu\/wp-content\/uploads\/sites\/20\/2019\/06\/surface-of-CNT-PDC-4-768x610.png 768w, https:\/\/mae.ncsu.edu\/cxu\/wp-content\/uploads\/sites\/20\/2019\/06\/surface-of-CNT-PDC-4.png 806w\" sizes=\"auto, (max-width: 260px) 100vw, 260px\" \/><\/td>\n<\/tr>\n<tr>\n<td style=\"width: 19.4892%;text-align: center\" colspan=\"2\">Figure 1.
