Mechanical property enhancement of flax fibers via supercritical fluid treatment.

ABSTRACT: The desire for lightweight, carbon-negative materials has been increasing in recent years, particularly as the transportation sector reduces its global carbon footprint. Natural fibers, such as flax fiber and their composites, offer a compelling combination of properties including low density, high specific strength, and carbon negativity. However, because of the low modulus and high variability in performance, natural fibers can't compete with glass fibers as structural reinforcements in polymer composites. In this study, flax technical fibers were treated in supercritical CO₂ (scCO₂), and the effects of this treatment on the morphology and properties of flax fibers are reported. Treatment in scCO₂ successfully resulted in higher fiber modulus and strength
