The optimization and evaluation of 3D-printed polylactic acid (PLA) materials for reinforcing concrete elements present a promising avenue advancing sustainable construction methods. This study addresses the challenges associated with PLA’s dual nature—biodegradable yet mechanically limited long-term applications—while leveraging its potential to enhance reinforcement. research identifies gaps in understanding mechanical chemical behavior alkaline environments, particularly interactions matrices. To bridge this gap, four distinct PLA variants (high-impact PLA, engineering electrical ESD gypsum PLA) ABS (acrylonitrile butadiene styrene) were subjected dissolution tests NaOH solutions (pH 12 12.55) under three-point bending using digital image correlation (DIC) technology. Test specimens prepared optimized 3D printing strategies ensure structural consistency embedded beams analyze their reinforcement potential. Force–displacement data GOM ARAMIS measurements revealed significant differences responses, peak loads ranging from 0.812 kN 1.021 (electrical PLA). Notably, exhibited post-failure load-bearing capacity, highlighting capability. Chemical material-specific degradation patterns, high-impact Gypsum showing accelerated surface changes precipitation phenomena. Observations indicated white crystalline precipitates, likely lime (calcium hydroxide—Ca(OH)2), residue (sodium hydroxide—NaOH), or material-derived residues formed on near elements, suggesting interactions. These findings underline critical role material selection achieving effective PLA–concrete integration. While environmental sustainability aligns industry goals, reliability exposure remains challenge. concludes that demonstrates highest application reinforced concrete, provided stability is managed, as value (1.021 kN) showed 25.7% higher capacity than (0.812 did not lose any tests. work advances alternative construction, offering insights future innovations applications.

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.

Impact of Fiber Morphology and Content on the Thermal Stability, and Mechanical Performance of Maple Wood Fiber‐Polypropylene Composites

Journal of Applied Polymer Science, Год журнала: 2025, Номер unknown

ABSTRACT In recent years, natural‐fiber‐reinforced polymers have gained significant attention due to their sustainability and enhanced properties. This study used Canadian maple wood fiber as reinforcement in a polypropylene (PP). Fiber length content are known key factors affecting the properties of composites. To investigate effects on thermal, mechanical, morphological properties, samples with 5%, 10%, 15%, 20% lengths 50, 75, 100 μm were prepared. The DSC results indicated that adding fibers altered exothermic endothermic peaks, increased melting points, decreased crystallization having more impact than length. TGA showed led lower thermal stability at temperatures but higher elevated temperatures. tensile tests revealed increasing up 15% improved strength, while further increase resulted decrease strength. These repeated for test, composites containing by volume lowest SEM analysis beyond certain content, accumulation occurred, negatively mechanical
