This study focuses on the thermophysical characterizations of composite materials made from polypropylene reinforced with residues and fibers from Borassus wood from Chad. These properties are experimentally determined at different temperatures using the hot wire method of the “FP2C” machine, where the hot wire probe is inserted between two specimens. The values of the thermal conductivity in powdered Borassus wood range from 0.170 W/mK to 0.182 W/mK for female wood (FNTF) and from 0.169 W/mK to 0.173 W/mK for male wood. For the female and male fibers, the thermal conductivity values range from 0.137 W/mK to 0.157 W/mK for the female and from 0.138 W/mK to 0.168 W/mK for the male. The thermal effusivity of the residues and fibers of Borassus wood varies from: 509.6 Ws^1/2/m²K to 543 Ws^1/2/m²K for the powder of female wood and from 524.6 Ws^1/2/m²K to 547 Ws^1/2/m²K for the powder of male wood. For the fibers of Borassus wood, the values range from 410.6 Ws^1/2/m²K to 523.6 Ws^1/2/m²K for the female wood fibers and from 420.3 Ws^1/2/m²K to 480.3 Ws^1/2/m²K for the male wood fibers. These results are important for the applications of Borassus wood residues and fibers in construction works regarding the thermal insulation of habitats.
