What is Natural Fiber Reinforced Polymer Springs?
Natural Fiber Reinforced Polymer Springs are helical or leaf springs manufactured from polymers reinforced with natural fibers like flax, jute, or kenaf to achieve lightweight, sustainable vibration damping in mechanical systems.
This subtopic examines mechanical properties such as tensile strength, compressive behavior, and interfacial bonding in natural fiber composites for spring applications. Key studies include chemical treatments for fiber enhancement (Khalid et al., 2021, 155 citations) and hybrid kenaf/glass composites (Sharba et al., 2016, 62 citations). Over 20 papers from 2010-2023 address feasibility, design, and testing, with foundational work on composite leaf springs (Kumar and Teja, 2013, 44 citations).
Why It Matters
Natural fiber reinforced polymer springs reduce vehicle weight by up to 50% compared to steel, improving fuel efficiency in automotive suspensions (Kumar and Teja, 2013). They enable eco-friendly alternatives in electric vehicles, addressing lightweight needs (Arifurrahman et al., 2018; Wazeer et al., 2022). Chemical treatments enhance durability for industrial applications (Khalid et al., 2021), while hybrid designs boost tensile properties (Sharba et al., 2016).
Key Research Challenges
Poor Interfacial Bonding
Natural fibers exhibit weak adhesion with polymer matrices due to hydrophilicity, reducing load transfer in springs. Chemical treatments like silane coupling improve bonding (Khalid et al., 2021). Processing changes degrade fiber properties further (Bourmaud et al., 2020).
Low Tensile Strength
Natural fibers like kenaf show inferior tensile performance versus synthetics under spring deflection. Hybridization with glass fibers enhances compressive and tensile properties (Sharba et al., 2016). Fabric reinforcement strategies mitigate this (Arumugam et al., 2022).
Thermal Degradation
Fibers lose stability at processing temperatures, affecting dynamic mechanical properties in vibrating springs. Kenaf/bamboo epoxy composites face thermal challenges (Chee et al., 2017). Property changes during composite processing exacerbate instability (Bourmaud et al., 2020).
