This work promotes the use of palm kernel shell powders associated with epoxy resin for the design of composite materials. Powders identification is carried out by FTIR analyses with vibrational movements. The crystalline character highlighted by DRX. The processing conditions with temperature favored the good behavior of the samples obtained with epoxy resin. A good behavior in water is observed on these samples. The best density result is the formulation T08_05_0125 which gives 1.9799 kg/m³, 1.8052 kg/m³ for T08 and 1.7719 kg/m³ for T05 and T0125. These results follow those of the compressive strength where the composition T08_0.5_0.125 gives the best results, namely 39.59KN for the 20/80 formulation, 37.17KN at 30/70, 36.92KN at 40/60 and 36.25KN at 10/90. These results follow those of the compressive strength where the composition T08_0.5_0.125 gives the best results, namely 39.59KN for the 20/80 formulation, 37.17KN at 30/70, 36.92KN at 40/60 and 36.25KN at 10/90. These results are those improved by to the temperature influence on the constituents during implementation. The compressive strengths in these particular temperature conditions are improved by 24.46% on average compared to those achieved at room temperature. The thermal behavior of the particles studied by TDA/TGA analysis made it possible to specify their capacity to contain heat and that for which the powder retains its intrinsic properties. These materials can be used in structural elements of mechanical engineering and civil engineering.
