摘要

Researchers are actively exploring the properties of natural fibers to develop innovative and sustainable materials for reinforcing lightweight composite structures. The focus is on date palm fibers, emphasizing the analysis of their mechanical and thermal properties to enhance traditional cement materials for modern construction applications. To achieve this goal, this study evaluates the impact of thermal stress on cement composite materials reinforced with date palm and doum palm fibers. A genetic algorithm is employed to investigate damage on both fibers and the matrix under varying stress levels, ranging from 25 to 37 MPa. Results indicate that the fiber–matrix interface damage is less pronounced in date palm/cement composites than in doum palm/cement composites. Remarkably, the fiber–matrix interface of date palm/cement composites exhibits less sensitivity to thermal stress than that of doum palm/cement composites. These findings contribute to the growing knowledge of using natural fibers in construction materials, furthering their potential applications.
