This work investigates the influence of crystallinity on mechanical properties needle-punched non-woven flax/polylactic acid (PLA) biocomposites with different flax fiber contents. Biocomposites were fabricated by a compression molding adopting cooling rates to understand mechanism and their contribution properties. Image-based analysis distribution in preform indicates probable origins residual porosities potential nucleation sites for crystal formation within composites. The improvement 25% 100% flexural modulus is observed composites 40% 50% mass fractions, respectively, when subjected lower rate, which implies significant void content brittleness impact decrease from 11% 18% according fraction rate decreases 1 °C/min, become more brittle. induced are compared those other literature emphasize applicability semi-structural applications.

Natural-Fiber-Reinforced Polymer Composites for Furniture Applications

Polymers, Journal Year: 2024, Volume and Issue: 16(22), P. 3113 - 3113

Published: Nov. 6, 2024

Increasing environmental awareness has driven a shift in furniture production from traditional materials, such as wood and wood-based panels, to sustainable environmentally friendly alternatives, natural-fiber-reinforced (NFR) composites. Environmental consciousness become key factor both consumer choices, with growing demand for sustainably sourced eco-friendly manufacturing processes, durable that helps reduce the impact of disposable products on environment. This paper analyzes various requirements polymer composites used applications, including performance, structural–functional, ecological, economical, safety requirements. It discusses factors influencing performance composite selection matrix reinforcing fibers, matrix-to-reinforcement ratio, choice technology, well compatibility bonding between fibers. Additionally, several standards commonly determine mechanical, physical, chemical properties these materials are presented.

Multiscale numerical analysis and experimental investigation on low-velocity impact damage tolerance of 3D woven composite joints

Mechanics of Advanced Materials and Structures, Journal Year: 2025, Volume and Issue: unknown, P. 1 - 14

Published: Feb. 20, 2025

The low-velocity impact damage tolerance of 3D woven composite joints is investigated by multiscale numerical and experimental methods. Microscale, mesoscale, macroscale models are developed to analyze the interactions between fibers, matrix, structures. microscale fiber, interfacial behavior examined identify critical failure mechanisms. mesoscale model focuses on influence yarn morphology sliding initiation propagation paths. At macro scale, analysis results joint have good agreement with experiments, revealing impact-induced its post-impact tensile behavior.
