“…The energy absorption considered the specific energy absorption, where the density was determined using Eq. (12) [9,34], which was combined with the weight criteria. The product cost took into account the raw material price in USD/kg and also the world production (availability) in 10 3 tonnes of the natural fibers.…”

“…For example, DaimlerChrysler has developed up to 50 car parts using bio-based materials [6,7]. The reasons why automotive industries are taking a big step on using NFC is because their lightweight properties can improve vehicle fuel consumption and are environmental friendly for recycling and safe disposal [8,9]. In the context of having plenty of natural fibers available sporting different mechanical and material properties, the selection of the material needs to be analyzed prior to product design and development.…”

The enforcement on sustainable design and environmental-friendly products has attracted the interest of researchers and engineers in the context of replacing metals and synthetic fibers with natural based fibers, especially in the automotive industry. However, studies on sustainable natural fiber material selection in the automotive industry are limited. Evaluation for the side-door impact beam was conducted by gathering product design specification from literature which amounted to seven criteria and it was forwarded to ten decision makers with automotive engineering and product design background for evaluation. The weightage required for decision-making was obtained using the Analytic Hierarchy Process (AHP) method based on six criteria. Following this, the best natural fiber materials to be used as reinforcement in polymer composites were selected using the VIseKriterijumska Optimizacija I Kompromisno Resenje (VIKOR) method. The results using both the AHP and VIKOR method showed that kenaf was the best natural fiber for the side-door impact beam composites. The result showed the lowest VIKOR value, QA1 = 0.0000, which was determined to be within the acceptable advantage and acceptable stability conditions. It can be concluded that the application of integrated AHP-VIKOR method resulted in a systematic and justified solution towards the decision-making process.

“…With the targeted control of the properties from the molecular structure to the composite, completely new applications are conceivable in addition to the significant improvement of existing composite materials for lightweight applications. These include new crash-absorbing structures in automotive engineering [2], more efficient gas diffusion structures for fuel cells [3], adsorptive fibers for hydrogen high-pressure tanks, next-generation energy storage systems, cell-compatible fibers to replace nerve tracts in paraplegia, prosthetics with tailored properties to avoid stress shielding, and many more. In particular, low-cost carbon fibers (CFs) are particularly interesting as reinforcement structures for carbon concrete [4] or for wind turbine rotor blades [5], since ecological and financial aspects play a particularly important role in the CF quantities required there.…”

Research and Development in Carbon Fibers and Advanced High-Performance Composites Supply Chain in Europe: A Roadmap for Challenges and the Industrial Uptake

Structural materials, typically based on metal, have been gradually substituted by high-performance composites based on carbon fibers, embedded in a polymer matrix, due to their potential to provide lighter, stronger, and more durable solutions. In the last decades, the composites industry has witnessed a sustained growth, especially due to diffusion of these materials in key markets, such as the construction, wind energy, aeronautics, and automobile sectors. Carbon fibers are, by far, the most widely used fiber in high-performance applications. This important technology has huge potential for the future and it is expected to have a significant impact in the manufacturing industry within Europe and, therefore, coordination and strategic roadmapping actions are required. To lead a further drive to develop the potential of composites into new sectors, it is important to establish strategic roadmapping actions, including the development of business and cost models, supply chains implementation, and development, suitability for high volume markets and addressing technology management. Europe already has a vibrant and competitive composites industry that is supported by several research centers, but for its positioning in a forefront position in this technology, further challenges are still required to be addressed.

“…Metals in turn offer relatively cost-efficient solutions with well understood and stable energy absorbing mechanisms. Taking into account higher tolerances for weight reduction costs for alternatively driven vehicles (Lukaszewicz, 2013), combining fibre-reinforced plastics (FRPs) and metals into hybrid material systems with two discrete material phases could open new possibilities in terms of weight-specific functional performance under crash. These new developments are part of a general trend of material diversification and specialisation in modern BiWs (Friedrich et al, 2008;Eickenbusch and Krauss, 2013), where each material systems' properties are supposed to suit the specific loading situation in the respective structural application.…”

The application of hybrid material systems composed of advanced composites and metals in automotive crash structural applications holds significant potential in terms of lightweighting and functional improvements. This paper proposes a comprehensive methodology to assess the suitability of vehicle body components for the application of hybrid material systems by analysing superimposed numerical crash simulation data of conventional steel bodies-in-white. The loading anisotropy and the global deformation are presented as two suitability criteria including an evaluation methodology to eventually select suitable hybrid material systems in the transition from conventional to enhanced material employment and vehicle structure design. Additionally, the methodology provides novel insights into the global structural loading by simultaneously considering multiple crash load cases
