Mechanical Performance and Dimensional Stability of Bamboo Fiber-Based Composite

Area of Science:

• Materials Science
• Composite Materials
• Wood Science

Background:

• Bamboo fiber-based composites (BFBCs) offer promising mechanical properties and dimensional stability.
• Optimizing processing parameters is crucial for enhancing BFBC performance.

Purpose of the Study:

• To investigate the impact of hot-pressing temperature and density on BFBC properties.
• To provide data for the design and application of BFBCs.

Main Methods:

• BFBCs were fabricated using hot-pressing at temperatures ranging from 150°C to 200°C.
• Composites were designed with densities of 1.05, 1.10, 1.15, and 1.20 g/cm³.
• Mechanical properties, dimensional stability, and color changes were evaluated.

Main Results:

• Increasing hot-pressing temperature led to decreased mechanical properties and improved dimensional stability.
• Holocellulose content decreased and BFBC color darkened with higher temperatures.
• Increased density significantly enhanced the modulus of elasticity (MOE) and reduced thickness swelling ratio (TSR), width swelling ratio (WSR), and water absorption ratio (WAR) by over 30%.

Conclusions:

• Processing temperature and density are critical factors influencing BFBC characteristics.
• Optimized density significantly improves dimensional stability and mechanical performance.
• Findings support the broader application and popularization of BFBCs.
