摘要：
Bio-composites (FF-PFA-D) were successfully compression moulded by reinforcing polyfurfuryl alcohol (PFA) with 10 layers of woven flax fabric (FF). FF-reinforced PFA-based bio-composites were then immersed in water to get wet bio-composite samples (FF-PFA-W). Mechanical and impact properties of the bio-composites in dry and wet state were determined. Characterisations of the bio-composites were performed by thermogravimetric analysis, thermomechanical behaviour, and cone calorimeter data. Results indicated the increase in alpha-relaxation temperature for FF-PFA-W. SEM micrograph showed that the flax fibres were completely coated with the resin indicating complete wetting of the fabrics by the matrix. As expected, time of ignition showed an increase for the bio-composites due to the flame retardant characteristics of PFA. This work gives us simple and effective way to prepare bio-composites from 100 % renewable resources.
