“…Common fillers include metals, ceramics, and carbon, while common fiber materials include glass fibers and carbon fibers. At present, there are already some insulating resin matrix composites that have been more maturely studied and applied, such as epoxy-resin-based glass fiber-reinforced composites, phenolic-resin-based glass fiber-reinforced composites, and epoxy-resin-based nanocomposites [4,5]. With the continuous pursuit of safety of power equipment, insulation performance, and temperature resistance in special environments, the research on resin matrix composites will continue to be in-depth and is expected to play a more important role in the field of insulation, providing lasting support for the reliable operation of power systems.…”

The research and application progress of resin-based composite materials in the field of electrical insulation has attracted considerable attention and emerged as a current research hotspot. This review comprehensively summarized the research and application progress of resin-based composite materials in the field of electrical insulation, providing detailed insights into their concept, properties, and preparation methods. In addition, a comprehensive evaluation of the electrical insulation performance, mechanical properties, and thermal properties of resin-based composite materials was presented, along with an in-depth analysis of their current application status. Despite the immense potential and development opportunities of resin-based composite materials, they also face several challenges. This review serves as a valuable reference and resource for researchers in related fields and aimed to promote further research and application development of resin-based composite materials in the field of electrical insulation.

In recent years, the transport industry has increasingly been confronted with the need for construction solutions that, at parity of performance, minimise the weight of products to save on fuel consumption, with benefits for operating costs and reduced pollutant emissions. In parallel, great attention has been paid to the challenge of integrating more sustainable circular approaches to manufacturing, which involve optimising the entire product cycle, from design to fabrication, assembly, and eventual reuse/recycling. In this context, the use of thermoplastic composite materials in combination with adhesive bonding is attracting increasing attention to achieve this dual objective. Therefore, the proposed research focuses on the experimental and statistical optimisation of an adhesive bonding process for glass-fibre reinforced composite substrates with polypropylene matrix. A low-pressure plasma pre-bonding surface treatment is adopted, and its effectiveness in enhancing joint performance compared to more conventional preparations for plastics is discussed. By varying plasma parameters according to the Design of Experiments statistical approach, the joint response is studied in terms of tensile shear strength and modelled in accordance with the Response Surface Methodology to identify the optimum condition of process parameters within the established system boundaries. Two alternative scenarios – namely, joints with thermoplastic composite or thermoset composite substrates – are then analysed by Life Cycle Assessment methodology and compared according to their relative environmental impact, demonstrating that glass-fibre thermoplastic composite joints are competitive alternatives to thermoset joints in terms of mechanical performance achieved, but significantly preferable with regard to environmental sustainability.

“…Parts made from prepregs present unique features, such as high fiber volume content and relatively easy manufacture . Normally, to achieve better quality parts and higher manufacturing velocities prepregs are combined with automated processing technologies such as automated fiber placement or automated tape laying, especially in the aerospace industry where high-quality requirements are imposed. , At this stage, the volume of production of CFRP has increased along with a corresponding rise in waste generation associated with its manufacturing process. This presents important challenges from both an economic and environmental perspective and underscores the need for sustainable approaches to the production, processing, and reuse of materials.…”

“…CFRP final properties are strongly linked to diverse parameters such as fiber content, orientation, or the selected manufacturing process. , In this way, focused on structural parts, the use of preimpregnated fibers, so-called prepregs, is one of the most well-known methods to develop high-performance CFRPs.

The continuous growth in the use of preimpregnated semielaborated products to manufacture continuous carbon fiber-reinforced polymer parts has led the industry to face an important challenge in the management of the prepreg scrap, as the amount of waste produced can reach almost 75% due to the inefficiency of the cutting phase. In this context, this industry is pushed to move toward a circular economy approach by conferring a new use to their waste. The main problem arises from the fact that shortening carbon fiber leads to nonefficient mechanical reinforcement and that other thermal or chemical recycling approaches are environmentally hazardous. In this work, mechanical recycling of carbon fiber prepregs from expired virgin prepregs or scrap from an automated manufacturing operation is proposed as an economical and environmentally efficient method to obtain multifunctional coatings with Joule effect heating capabilities, which are demanded by different industries as a high-value product. As a coating, mechanical performance is not so relevant; nevertheless, obtaining high electrical conductivity by the incorporation of proper size and distributed short recycled carbon fiber can lead to a self-heating coating that could be used for anti- and deicing purposes or any other thermally activated function with very low power consumption. In this way, electrical conductivities up to 2 S/m were obtained, which allowed for achieving temperatures of 200 °C by the Joule effect in all samples in less than 17 s by the application of voltages below 48 V for bulk materials and 100 V for the coating.
