Reinforcement of Polyurethane Foam Using Micro–fiber from Banana pseudostem

Abstract
Banana pseudostem, an abundant
agricultural byproduct, was utilized as a sustainable fiber source to reinforce plastic
composites, addressing both waste management and material performance.
The study commenced with the extraction of banana pseudostem fiber using a
chemical treatment process optimized for high yield and fiber quality. The composites
were analyzed for their chemical composition and structural integrity through
Fourier-transform infrared spectroscopy (FTIR). FTIR analysis provided insights into
the functional groups present in the fibers and their interaction with the plastic matrix.
Scanning Electron Microscopy (SEM) was employed to analyze the fiber morphology
and the interfacial bonding between the fibers and the plastic matrix. SEM images
illustrated the surface characteristics of the fibers and provided evidence of good
fiber-matrix adhesion, contributing to the improved mechanical properties of the
composites.
The project also involved calculating the percentage yield of the extracted fibers and
assessing their moisture content. These parameters are crucial for determining the
practical applicability of the fibers in large-scale manufacturing processes. This
project demonstrates the feasibility of utilizing banana pseudostem fibers as a
reinforcing agent in polyurethane foam matrices. The results suggest that banana
pseudostem fibers offer a viable alternative to conventional reinforcement materials,
providing a cost-effective and eco-friendly solution for innovative foam production.
