Carbon Nanotubes (CNT) have intrinsic electrical and mechanical properties making them potentially attractive materials for use in lightweight spacecraft structures and subsystems. In the field of electronic or structure in space application, the needs of material developments are focused on adapted thermal properties for high temperature gradient or high stability for structural parts or bonding of elements like sandwich structures. CNT papers were infiltrated by a cyanate ester resin matrix, and the resulting thermal and electrical properties compared to those obtained using carbon fibers. Sufficient matnx conductivity for anti-static applications can be achieved at lower CNT concentrations. The thermal conductivity of all produced samples is too low to dissipate energy in electronic packaging or any heating device. The CTE values are decreased at a CNT weight fraction of 25% to reach 15.10-6/K. A little bit higher than the value of a carbon fiber. This is however a quite high decrease and could be used in conventional CFRP (Carbon Fiber Reinforced Plastics) composite to reduce the mismatch of CTE between the fibers and the matnx.
