Abstract

Carbon fiber composites have emerged as a transformative technology, offering a fascinating alternative to traditional materials like aluminum and steel. Their unique combination of high strength, stiffness, and reduced density makes them an ideal choice for lightweight structural components, an attribute that aligns with the pursuit of fuel-efficient and eco-friendly aircraft designs. With the continuous race between countries and research organizations to find new materials that satisfies the above-mentioned characteristics, this article highlights the utilization of a new Ultra-Light Carbon-based Composite (ULCC) in the aeronautical sector developed within the industrial research project TERSA (Radar technologies for autonomus flying vehicles or TEcnologie Radar per Sistemi aerei a pilotaggio remoto (SAPR) Autonomi in italian). The composite material has been developed with the aim of achieving superior performance and efficiency compared to existing products on the market. To evaluate its effectiveness, first, the mechanical properties of the ULCC have been compared to T300/Epoxy and T1000/Epoxy, two of the materials commonly used in aeronautical industry and unmanned aerial vehicle (UAV). Second, finite element models were employed to verify and analyze the dynamic properties of aeronautical structural components made of ULCC. The results indicate that the new carbon-based composite exhibits remarkable strength-to-weight ratio, enhanced durability, and offering significant advantages in terms of weight reduction and overall performance. These findings validate its potential as a viable alternative in aeronautical industry.

用于航空领域超轻型应用的碳纤维复合材料编织层压板的力学分析
碳纤维复合材料已成为一种变革性技术,为铝和钢等传统材料提供了一种令人着迷的替代材料。碳纤维复合材料集高强度、高刚度和低密度于一身,是轻质结构组件的理想选择,这与飞机设计追求节油和环保的理念不谋而合。随着各国和研究机构不断努力寻找满足上述特性的新材料,本文重点介绍了一种新型超轻碳基复合材料(ULCC)在航空领域的应用,该材料是在工业研究项目 TERSA(自主飞行器雷达技术,意大利语为 TEcnologie Radar per Sistemi aerei a pilotaggio remoto (SAPR) Autonomi)中开发的。开发这种复合材料的目的是使其性能和效率优于市场上的现有产品。为了评估其有效性,首先将 ULCC 的机械性能与 T300/Epoxy 和 T1000/Epoxy 进行了比较,这两种材料常用于航空工业和无人驾驶飞行器(UAV)。其次,采用有限元模型验证和分析了 ULCC 制成的航空结构部件的动态特性。结果表明,这种新型碳基复合材料具有出色的强度重量比、更高的耐久性,在减重和整体性能方面具有显著优势。这些研究结果验证了其作为航空工业可行替代品的潜力。
