“…This solution, however, is challenging as the aerospace manufacturing industry is tightly controlled and is subject to stringent regulations that require lengthy approval processes. Regardless of the challenges of using alternative materials, there is an upward trend in these aspects, particularly with regards to the use of composites [13] and additive manufacturing technologies [14]. Although these new materials and manufacturing technologies seem promising, there is a risk that the environmental impact might from one life cycle phase to another.…”

In this paper, a life cycle assessment (LCA)-based sustainability assessment framework is developed to estimate the environmental impact of production processes. The framework provides a methodical, context-independent, approach to carry out LCA studies. The framework sets guiding principles for products and key performance indicators (KPIs) selection and the associated data requirements in a reconfigurable manner that can be applied to any industrial setting. In order to validate and demonstrate the applicability of the framework, a cradle-to-gate case study pertaining to the manufacturing of a real aerospace metallic structural component is carried out. Results revealed that the complexity of aerospace components makes it difficult to improve the environmental impact from manufacturing operations as most of the impact comes from upstream activities that aerospace manufacturers, typically, have no control over, or access to.

“…Composite laminates often possess microscopic defects from the manufacturing process. These can develop into larger cracks and result in delamination and failure of the part when applied with high stress, whether from the normal working conditions over time, or from impact of a foreign object such as a bird strike, hail or a dropped tool [27]. Determining fracture toughness and damage tolerance is therefore vital to inform the design of composite structures.…”

We review the literature describing the use of interleaves to increase interlaminar fracture toughness in fibre-reinforced polymer composites and hence to improve damage tolerance. From an analysis of data provided in the literature from the use of microfibre and nanofibre interleaves, we show that the performance of these widely researched systems is clearly differentiated when plotted against the mean coverage of the interleaf. Using a simple analysis, we suggest that this can be attributed to the influence of their porous architectures on the infusion of resin. We show also that the superior toughening performance of microfibre interleaves is only weakly influenced by the choice of fibre. We find also that the inclusion of carbon nanotubes within interleaves to deliver multifunctional composites can be optimised by using a hybrid system with microfibres. Graphical abstract

“…The measurement of fracture of fibrous polymeric composite is still a research area. Some failure modes, such as mode I, mode II, and mixedmode I/II, have been developed to predict fibrous polymeric composites' fracture behavior closely [136].…”

Polymeric composites are used worldwide due to their enhanced applications in various sectors such as automotive, defense, aerospace, marine, and many others. Its lightweight and high‐strength applications make it convenient to use in high‐security fields such as defense and aerospace. Thus, it is essential to characterize composite materials for product development. Numerical simulation of composites has advantages over experimental characterization. The paper presents the mechanical behavior of polymer textile composites, employing geometrical modeling and a numerical simulation approach, under several loading conditions such as tension, compression, flexural, and impact loading. Failure mechanisms are also discussed with different failure modes and damage criterions. This review paper is limited to high‐strength fibers, such as carbon, Kevlar, and Glass fibers in unidirectional and woven formation. Various test specimens used in mechanical characterizations are presented with significant research summaries. Classification charts are also provided for a better understanding of the numerical simulation approach for characterizing the mechanical behavior.
