Overview

Randomized trial investigates moisture content impact on flax-epoxy biocomposite quality, suggesting optimal manufacturing conditions.

Key Points

  • This research aims to understand how moisture content changes during the manufacturing of flax-epoxy biocomposites and its effects on composite quality.
  • Investigated moisture content during Vacuum Assisted Resin Transfer Moulding (VARTM) steps.
  • Monitored changes during compaction, curing, and service life under varying temperature and relative humidity conditions.
  • Analyzed moisture desorption and sorption behaviors under controlled temperatures and humidity.
  • Moisture content decreased from 12% to 7% at 50°C over 72 hours, demonstrating desorption influence by temperature.
  • A slight moisture decrease of 0.7% occurs during curing, with post-curing showing no significant desorption.
  • Temperature significantly affects equilibrium moisture content only above 70% relative humidity, indicating specific conditions for optimal composite quality.
