Epoxy-based hybrid composites reinforced with Amazonian Tucuma endocarp and kaolin: A statistical approach to mechanical properties

Antonio Claudio Kieling et al.

Summary: Tucuma powder and white kaolin from the Amazon are mixed with epoxy polymer to create a hybrid composite with reduced petroleum content. The effects of Tucuma and kaolin content on the compressive and tensile properties of the composite are studied using statistical design and analysis. The results show that composites with 42% Tucuma and 2% kaolin have improved compressive performance and similar strength to the original polymer, while tensile strength and toughness are reduced due to interfacial discontinuities.

A critical review of the ultrastructure, mechanics and modelling of flax fibres and their defects

Emmanuelle Richely et al.

Summary: The market for plant-fibre reinforced composites has been growing steadily due to environmental legislation and global warming effects, but uncertainties regarding defects in plant fibres decrease mechanical properties at the composite scale. Finite element modelling has emerged as a crucial tool in understanding these defects, particularly in complex plant fibre ultrastructures compared to synthetic materials. Through a top-down and multi-scale approach, this review addresses advanced testing methods and numerical approaches to capture the complex mechanical behaviour of plant fibres.

Tribological and mechanical performances of newly developed eco-epoxy composites incorporating flax fibres and graphene nanoplatelets

K. Y. Eayal Awwad et al.

Summary: The inclusion of both fibre and solid lubricants in polymers can enhance their tribological and mechanical performances. This study investigates the effects of incorporating flax fibres and graphene nanoplatelets (GNPs) in epoxy matrix composites on their tensile, microhardness, and adhesive wear behavior. It was found that the addition of flax fibres improved the stiffness and tensile strength of the epoxy, while the inclusion of GNPs reduced the interface temperature and coefficient of friction. The heat distortion temperature was identified as a key parameter controlling the wear behavior of the composites.

Mechanical characterization of mortar reinforced by date palm mesh fibers: Experimental and statistical analysis

Hocine Khelifa et al.

Summary: This study investigated the influence of four parameters on the bending and compression properties of bio-fiber reinforced mortar using short Mesh date palm fibers in a cement matrix. The results showed that incorporating mesh date palm fibers into the mortar improved the mechanical properties significantly. The optimization of mechanical properties showed promising results with notable increases in bending stress and modulus compared to the reference mortar case.

Wood-plastic Composite Based on Recycled Polypropylene and Amazonian Tucuma (Astrocaryum aculeatum) Endocarp Waste

Antonio Claudio Kieling et al.

Summary: The study investigated a novel wood-plastic composite made from recycled polypropylene and Tucuma endocarp powder without coupling agents, which addresses social and environmental issues. The addition of Tucuma endocarp powder can increase the elastic modulus and dynamic friction coefficient, while reducing the strength and burning rate, showing potential for sustainable engineering applications.

Composite Material Recycling Technology-State-of-the-Art and Sustainable Development for the 2020s

Andrey E. Krauklis et al.

Summary: The recent events, such as the ban on composite landfilling in Germany, decommissioning of composite wind turbines, acceleration of aircraft decommissioning, and increase of composites in mass production cars have significantly increased the pressure for developing sustainable composite recycling solutions. The authors of the study propose that identifying optimal recycling methods for various types of fiber reinforced composites is crucial for the future. The manuscript provides a comprehensive overview of recycling technologies for fiber reinforced composites at both low and high Technology Readiness Levels, aiming to guide the sustainable development of the industry and benefit the society.
