This study aims to examine the morphology and mechanical properties (tensile, flexural, and compressive) of epoxy composites reinforced with epoxy date palm leaves (EDPL), epoxy date palm branch (EDPB), and epoxy/hardener date palm core shell (EDPC) fibers (particle size <1 μm depend on the date palm fibers). A three‐step technique was used to obtain the composites. The EDPL composites showed a maximum tensile strength of 3.45 MPa, while the EDPB composites showed maximum compressive and flexural rigidity of 9.46 and 5.55 MPa, respectively, owing to the good compatibility of fiber‐matrix bonding. In this work, epoxy composites reinforced with date palm fibers (DPF) leaves, branches, and core shell were recycled using a cost‐effective and easily reproducible three‐step technique. EDPC fibers fabricated with 64.65% weight carbon fibers content demonstrated improved tensile strengths and stiffness properties. The three samples of palm date composites revealed mechanical properties that could be used to trial these fibers for manufacturing purposes, and to exploit their extraordinary mechanical properties shown in current results.

枣椰子纤维增强环氧结构复合材料的形态和力学性能研究

这项研究旨在检查用环氧枣椰子叶（EDPL），环氧枣椰子分支（EDPB）和环氧/硬化枣椰子核壳（EDPC）增强的环氧复合材料的形态和力学性能（拉伸，弯曲和压缩）。纤维（粒径<1μm取决于枣棕纤维）。使用三步法获得复合材料。EDPL复合材料的最大抗拉强度为3.45 MPa，而EDPB复合材料的最大抗压刚度和抗弯刚度分别为9.46和5.55 MPa，这归因于纤维-基体粘结的良好相容性。在这项工作中，使用成本效益高且易于重现的三步法回收了用枣棕纤维（DPF）的叶子，树枝和核壳增强的环氧复合材料。用64制造的EDPC纤维。碳纤维含量为65％（重量）时，拉伸强度和刚度性能得到改善。棕枣复合材料的三个样品显示出机械性能，这些机械性能可用于出于制造目的试用这些纤维，并利用当前结果中显示的非凡机械性能。
