Paragraph starter

Research by Głowińska et al. (2017) demonstrates that incorporating sisal fibers into bio-based polyurethane composites significantly enhances their thermal stability and mechanical properties. Specifically, the addition of 5% and 15% sisal fibers improved the material's resistance to degradation at high temperatures and positively influenced its storage and loss modulus, indicating better structural integrity and energy dissipation. This suggests that natural fiber reinforcement is a viable strategy for developing more robust and sustainable bio-composite materials.
