Nowadays, convectional metallic material replaced by composite materials, because composite materials have superior than metallic materials properties such as light weights, higher strength-to-weight ratio, high tensile strength, Low cost, greater design flexibility, better fatigue resistance, renewability, and biodegradability. These properties of composite material are the most basic & common attractive features that make them useful for industrial applications. The main objective of this work is to contribute for a better understanding of the static behavior of structure made from fiber reinforced composite materials, specifically for the case of plate structures. The plate model is created using SOLIDWORKS 2017 and then imported into ANSYS R18.1. The study specifically examines three stacking sequences of the composite plate (angle ply, cross ply, and multidirectional ply) to analysis stress and deformation resulted from the loads. The static analysis of a Carbon/Epoxy with honeycomb plate composite reveals that the equivalent stress and deformation are lower in the cross-ply stacking sequence compared to the angle ply and multidirectional ply for the same load carrying capacity. This suggests that the composite plate with a cross ply configuration is more suitable for manufacturing composite structures due to its improved performance.
如今，传统金属材料已被复合材料取代，因为复合材料具有优于金属材料的性能，如重量轻、强度重量比高、拉伸强度高、成本低、设计灵活性大、抗疲劳性好、可再生和可生物降解性。复合材料的这些性能是使其在工业应用中有用的最基本和常见的吸引人的特性。这项工作的主要目的是有助于更好地理解由纤维增强复合材料制成的结构的静态行为，特别是对于板结构的情况。使用SOLIDWORKS 2017创建板模型，然后导入ANSYS R18.1。该研究具体检查了复合板的三种堆叠顺序（角铺设、正交铺设和多向铺设），以分析载荷产生的应力和变形。对带有蜂窝板复合材料的碳/环氧树脂的静态分析表明，在相同承载能力下，与角铺设和多向铺设相比，正交铺设堆叠顺序中的等效应力和变形更低。这表明具有正交铺设配置的复合板由于其性能的改善而更适合制造复合结构。
