Abstract

Abstract This study evaluated the mechanical properties of the scrimber wood produced from date palm fronds and compared it to other wood-based materials. The raw materials for the production of the scrimber wood were date palm fronds. The scrimber wood was produced using a fabrication process that included the following stages: washing, cutting, burning, and gluing the pieces. The results showed that the mechanical properties of the scrimber wood produced using date palm fronds were very similar to those of other woods used for the same purpose. It was found that the wood produced was strong enough to hold several heavy objects without deforming or breaking. In addition, no defects, such as cracks or holes, were observed on the surface of the wood after processing. The results revealed that frond-scrimber trees recorded the largest deflection before fracture due to their fibrous features. The fibrous structure of the frond scrim may explain its strength and durability, as it successfully supplied samples with high fracture points, similar to hardwood, and prolonged maximum displacement, similar to certain softwoods. The dynamic characterization of the scrimber wood specimens reveals their inherent frequencies, mode forms, damping ratios, and other dynamic properties; such insights may help forecast their performance under different loads.

评估用枣椰树叶制成的修剪木的机械和动态特性

摘要本研究评估了用椰枣叶生产的修边材的机械性能，并将其与其他木质材料进行了比较。生产修边材的原材料是椰枣叶。这种修边材的制作过程包括以下几个阶段：清洗、切割、烧制和粘合。结果表明，使用枣椰树叶制作的护网木材的机械性能与用于相同目的的其他木材非常相似。研究发现，这种木材的强度足以支撑多个重物而不会变形或断裂。此外，加工后的木材表面没有发现裂缝或孔洞等缺陷。研究结果表明，由于其纤维结构特点，锋面锯齿树在断裂前的挠度最大。冠幅材的纤维结构可以解释其强度和耐久性，因为它成功地提供了与硬木类似的高断裂点样本和与某些软木类似的长时间最大位移样本。对无纤网木材试样的动态表征揭示了它们的固有频率、模态形式、阻尼比和其他动态特性；这些见解可能有助于预测它们在不同负载下的性能。

期刊介绍： The journal focuses on the micromechanics and nanomechanics of materials, the relationship between structure and mechanical properties, material instabilities and fracture, as well as size effects and length/time scale transitions. Articles on cutting edge theory, simulations and experiments – used as tools for revealing novel material properties and designing new devices for structural, thermo-chemo-mechanical, and opto-electro-mechanical applications – are encouraged. Synthesis/processing and related traditional mechanics/materials science themes are not within the scope of JMBM. The Editorial Board also organizes topical issues on emerging areas by invitation. Topics Metals and Alloys Ceramics and Glasses Soils and Geomaterials Concrete and Cementitious Materials Polymers and Composites Wood and Paper Elastomers and Biomaterials Liquid Crystals and Suspensions Electromagnetic and Optoelectronic Materials High-energy Density Storage Materials Monument Restoration and Cultural Heritage Preservation Materials Nanomaterials Complex and Emerging Materials.
