“…The utilization of carbon fiber-reinforced plastics (CFRP) in engineered structures has significantly increased due to their exceptional properties, including low weight, high specific strength, great corrosion resistance, durability, and enhanced fatigue properties in comparison to traditional materials. [1][2][3] The manufacturing industry of machinery has made progress in the development of lightweight structures, progressively utilizing CFRP to attain moderate weight savings. [4] For example, Mahoney et al [5] detailed a lightweight carbon fiber composite chassis developed in the aircraft industry.…”

Nowadays, lightweight is an indispensable requirement in the development of automobile industry as one of the most effective methods of energy conservation and emission reduction. In this paper, the lightweight design of oil pan was carried out by using carbon fiber reinforced plastic material instead of metal material. In particular, the influence of manufacturing process was considered in the structural design, and an integrated design method of structure and process was proposed. According to the idea of comprehensive design, structural design, and composite design were carried out in parallel. Reasonably adjusted the geometric characteristics of the oil pan, further determined the feasible laying process scheme and filling process scheme, and finally the oil pan that meets the working conditions and lightweight objectives was manufactured. The work done in this paper can provide a certain reference for the lightweight design of other automobile parts.

“…It was shown that weight savings were possible by replacing current components with appropriate sandwich materials. In the numerical studies by Ahmed and Wei [ 6 ] and Sellitto et al [ 3 ], sandwich composites were introduced into the hood structure of a vehicle, thereby increasing pedestrian safety and reducing weight. Riccio et al [ 7 ] studied the impact behavior of honeycomb cores based on natural fibers, using numerical models accounting for damage.…”

Lightweight components are in demand from the automotive industry, due to legislation regulating greenhouse gas emissions, e.g., CO2. Traditionally, lightweighting has been done by replacing mild steels with ultra-high strength steel. The development of micro-sandwich materials has received increasing attention due to their formability and potential for replacing steel sheets in automotive bodies. A fundamental requirement for micro-sandwich materials to gain significant market share within the automotive industry is the possibility to simulate manufacturing of components, e.g., cold forming. Thus, reliable methods for characterizing the mechanical properties of the micro-sandwich materials, and in particular their cores, are necessary. In the present work, a novel method for obtaining the out-of-plane properties of micro-sandwich cores is presented. In particular, the out-of-plane properties, i.e., transverse tension/compression and out-of-plane shear are characterized. Test tools are designed and developed for subjecting micro-sandwich specimens to the desired loading conditions and digital image correlation is used to qualitatively analyze displacement fields and fracture of the core. A variation of the response from the material tests is observed, analyzed using statistical methods, i.e., the Weibull distribution. It is found that the suggested method produces reliable and repeatable results, providing a better understanding of micro-sandwich materials. The results produced in the present work may be used as input data for constitutive models, but also for validation of numerical models.
