Physical-Mechanical Properties of Bamboo Fiber Composites Using Filament Winding

Area of Science:

• Materials Science
• Composite Materials

Background:

• Filament winding is a common method for preparing fiber-reinforced composites.
• Natural fibers like bamboo offer a sustainable alternative to synthetic fibers in composite materials.

Purpose of the Study:

• To evaluate the performance of bamboo fiber composites prepared by filament winding.
• To compare bamboo fiber composites with jute and glass fiber composites.
• To investigate the structural and mechanical properties of these composites.

Main Methods:

• Scanning Electron Microscopy (SEM) for structural analysis.
• Tensile and bending tests for mechanical properties.
• Dynamic Mechanical Analysis (DMA) for thermal and viscoelastic properties.

Main Results:

• Bamboo fiber composites exhibited lower density and mechanical properties compared to jute and glass fiber composites.
• The internal structure of bamboo fibers, with resin not fully penetrating cell cavities, led to fiber pull-out and lower performance.
• Twisting bamboo fiber (TBF) composites showed the highest glass transition temperature (165.89 °C) and storage modulus (6000 MPa), indicating good plasticizing properties and elasticity.
• TBF composites demonstrated the least frequency dependence and performance variability.

Conclusions:

• The inherent structure of bamboo fibers limits their mechanical performance in composites.
• TBF composites offer enhanced thermal stability and elasticity due to restricted matrix molecular chain movement.
• Further surface and internal structure modifications of TBF are recommended to improve overall composite properties.
