Mechanical Properties Of Short Natural Fiberreinforced Thermoplastic Composites

Abstract

This study investigates the mechanical
properties of thermoplastic composites
reinforced with natural fibers and fillers.
Epoxy composites with jute fibers and
aluminum oxide (Al2O3) fillers were
analyzed, alongside hybrid composites
made from banana, kenaf, sisal, and glass
fibers. Various fabrication techniques,
such as hand lay-up and compression
molding, were utilized, and treatments like
sodium lauryl sulfate and alkali treatments
were applied to enhance fiber-matrix
bonding. Mechanical properties, including
tensile, flexural, and impact strengths,
were evaluated, and morphological
analysis using scanning electron
microscopy (SEM) provided insights into
fiber/matrix adhesion. Dynamic testing
under different support conditions
examined composite behavior. The study
revealed that fiber content, orientation,
and filler composition significantly
influence mechanical performance. The
optimal configurations demonstrated
enhanced strength and stiffness, making
these composites suitable for highperformance
applications in aerospace,
shipping, and sports industries. This
research underscores the potential of
natural fiber composites in advanced
engineering applications.
