Experimental physical and thermal characteristics of polypropylene composite materials from borassus wood residues and fibers from chad

This study focuses on the physical and thermal characterizations of composite materials made from polypropylene with the residues and fibers of Borassus wood from Chad. These properties are experimentally determined in various ways using the hot wire method of the "FP2C" machine, where the hot wire probe is inserted between the two specimens. The values of thermal diffusivity in powdered Borassus wood range from 1.084.10-7 m²/s to 1.112.10-7 m²/s for female Borassus wood and from 9.923.10-8 m²/s to 1.037.10-7 m²/s for male Borassus wood. For the female and male fibers of Borassus wood from Chad, the thermal diffusivity values range from 6.846.10-8 m²/s to 1.462.10-7 m²/s for the female fibers and from 8.254.10-8 m²/s to 1.597.10-7 m²/s for the male fibers of the wood.The thermal resistance of Borassus wood powders and fibers ranges from 0.076 to 0.082 for female powders and from 0.076 to 0.090 for male wood. For Borassus wood fibers, the values range from 0.068 m². K /W to 0.105 m2. K /W for female fibers and 0.075 m2. K /W at 0.084 m2 .K /W for the male fibers of Borassus wood. The density values in powdered Borassus wood range from 771,000 kg/m3 to 808,667 kg/m3 for female wood and from 779,000 kg/m3 to 872,667 kg/m3 for male wood.
