摘要：

This paper presents a study regarding the obtaining, characterization and testing of a new ablative type composite material, composed of simple and nanofilled bismaleimide resin with various mass concentrations of nanometric silicon carbide particles (nSiC), reinforced with graphite felt. After the obtaining process parameters were established, the materials were tested in terms of mechanical, thermo-mechanical (HDT), tribological and thermal properties (thermal shock conditions) and they were characterized from morphostructural point of view (optical and scanning electron microscopy). The experimental results indicated an improvement of the performance of the nanofilled material samples compared to the control sample in the tested conditions.
