AB - In this study, the mechanical properties of layered composite structures were investigated. We achieved the layered structure by hot-pressing 1 mm, 3 mm, or 5 mm thick polyamide 6 (PA) sheets into the pores on the top and bottom sides of an open-cell metal foam at 240 °C and 15 MPa (150 bar). The PA-infiltrated depths varied with the thickness of the hot-pressed PA sheets. According to the bending and post-impact bending tests, flexural strengths improved as the infiltration depth of PA increased. Compared to the metal foam, a maximum of 15% increase in flexural strength and a 400% increase in residual flexural strength were measured. However, using a 1 mm thick PA sheet lowered the flexural strength of the open-cell metal foam. We found that the 1 mm thick PA sheet failed to fully infiltrate the foam pores, resulting in residual voids at the metal-PA interface, which caused premature fracture during bending.

AB - This study examines the performance of hybrid sandwich composites with a recycled aluminium foam (AlF) core and a recycled carbon-reinforced polymer skin layer. Three composite skin configurations were examined: (i) unidirectional (UD) carbon/epoxy sheets representing aligned virgin fibre reinforcement, (ii) randomly oriented recycled carbon fibre (rCF) mats consolidated by hand layup with epoxy, and (iii) randomly oriented rCF/epoxy sheets consolidated by hot pressing. The AlF core structure analysis revealed a low density and uniform open-cell structure ideal for lightweight cores. Comprehensive testing revealed significant performance differences between skin types and manufacturing methods, underscoring the critical role of processing – particularly hot pressing – in enhancing fibre compaction, matrix consolidation and interfacial bonding between the core and facesheets. Unidirectional carbon fibre skins achieved the highest flexural stiffness. In contrast, hot-pressed rCF mats provided the most balanced properties, combining high compression, damage resistance, and flexural strength, due to improved consolidation and reduced porosity in the face sheets. Thus, hybrid sandwich structures fabricated from recycled AlF core and rCF represent a viable, environmentally responsible alternative for aerospace, automotive, and protective applications requiring lightweight, high-strength, and damage-resistant materials.

AB - This study shows the utilization of recycled carbon fibers (rCF) in nitrile butadiene rubber (NBR) to produce sustainable, high-performance elastomer-based mixtures. Recycled carbon fibers, sourced from composite waste, were incorporated into the NBR matrix with different concentrations using an internal mixer for compounding and hot pressing for vulcanization. Tensile, hardness, tear and abrasion tests, and a scanning electron microscopy study were performed to show the effects of rCF. The results indicate that moderate fiber contents significantly enhance the stiffness and tensile strength of NBR without compromising its inherent elasticity. Twenty phr recycled carbon fiber increased tensile strength by 15% but decreased strain by 16% and almost doubled stiffness compared to the reference. The addition of carbon fibers caused an increase in hardness proportionally with the amount of reinforcement. 50 phr rCF increased Shore A hardness by 30%. When rCF was added, abrasion resistance increased significantly; 10 phr carbon fiber halved the amount of abraded material. Microscopic examinations confirmed the significance of fiber dispersion and adequate bonding at the matrix–fiber interface for optimal load transfer. The possibility of foaming was analyzed, and the hypothesis was proved. The results demonstrate the viability of recycled carbon fibers as a reinforcement in NBR, which also highlight the environmental and economic benefits associated with recycling composite materials in the rubber industry.

AB - The objective of our study was to investigate and describe the durability of mono and hybrid composite materials reinforced with various fabrics (namely, glass, carbon, and basalt) and an epoxy resin matrix against repetitive loads, with a particular focus on their potential use in wind turbine blades. The mechanical properties of these materials were evaluated through repeated tensile tests involving high deflection and low cycle numbers. A new approach was introduced for characterizing and comparing the performance of glass, carbon, and basalt fiber reinforced epoxy composites. Our results led to the development of a novel model to evaluate a new mechanical property, the asymptotic modulus, which can be used to assess the resistance of composite materials to multi-cycle tensile loads in a faster and simpler manner. Differences between the measured and by our model predicted values were low, the values of determination coefficient were higher than 94%.

As global demand for these materials continues to rise, effective management of waste generated during production and end-of-life cycles becomes imperative. Recycling technologies offer a promising solution, enabling the recovery of reinforcing materials and the circularization of material flows in the composites industry. This study investigates the potential of recycled carbon fibers (rCFs) as interlayers to enhance the interlaminar fracture toughness of carbon fiber/epoxy composites. Nonwoven mats based on rCFs are utilized to toughen a unidirectional carbon/epoxy laminate, aiming to improve Mode-I and Mode-II fracture toughness and fatigue performance. Fracture tests, augmented with acoustic emission (AE) and microscopic analysis of fracture surfaces, provide insights into the efficiency of incorporating rCF interlayers to enhance composite structures' long-term behavior and durability.
