Natural Fiber-Polymer Interfacial Adhesion
Research Guide

What is Natural Fiber-Polymer Interfacial Adhesion?

Natural Fiber-Polymer Interfacial Adhesion refers to the bond strength at the interface between natural fibers and polymer matrices in composites, characterized by microdroplet, microbond, and fragmentation tests.

Researchers evaluate interfacial shear strength (IFSS) using single-fiber tests to quantify adhesion. Moisture absorption weakens this interface, prompting studies on compatibilizers like silane-siloxane. Over 20 papers since 2023 analyze treatments for fibers such as kenaf, tucumã, and Amazon species.

Key Challenges

Why It Matters

Interfacial adhesion governs load transfer in natural fiber reinforced composites, directly affecting tensile strength and fatigue life under humid conditions (Piedad Gañán et al., 2023). Silane treatments on tucumã fibers improved mortar flexural strength by 15-20% (Carmelita Blodow do Nascimento et al., 2024). In kenaf-basalt hybrids with TiO2 nanoparticles, enhanced adhesion boosted thermal stability up to 500°C (T. Sathish et al., 2024), enabling durable applications in automotive panels and construction.

Key Research Challenges

Moisture-Induced Debonding

Natural fibers absorb water, swelling and reducing IFSS by up to 40% in humid environments. Fragmentation tests reveal matrix cracking at 60% relative humidity. Pedro Henrique Poubel Mendonça da Silveira et al. (2024) highlight Amazon fiber sensitivity.

Compatibilizer Efficacy Variability

Silane-siloxane treatments show inconsistent adhesion gains across fiber types like tucumã and kenaf. Microbond tests indicate 10-25% IFSS improvement but poor long-term stability. Carmelita Blodow do Nascimento et al. (2024) report variable mortar performance.

Interface Characterization Scalability

Microdroplet and fragmentation tests are labor-intensive, limiting high-throughput screening. Standardization lacks for hybrid fibers like kenaf-basalt. T. Sathish et al. (2024) used TGA but note scalability issues for nanocomposites.
