In-Situ Monitoring Of The Ultrastructure And Mechanical Properties Of Flax Cell Walls During Controlled Heat Treatment
Abstract
Plant fibres are increasingly used as reinforcements, especially in thermoplastic composites. Understanding the impact of temperature on the properties of these fibres is an important issue for the manufacturing of high-performance materials with minimal defects. In this work, the structural evolution and mechanical behaviour of flax fibre cell walls were dynamically monitored by temperature-controlled X-ray diffraction and nanoindentation from 25 to 230°C; detailed biochemical analysis was also conducted on fibre samples after each heating step. With increasing temperature up to 230°C, a drop in the local mechanical performance of the flax cell walls was measured. This was associated with a decrease in the packing of the cellulose crystal lattice (increase in d-spacing d200), as well as significant mass losses measured by TGA and changes in the biochemical composition, i.e. non-cellulosic polysaccharides (NCPs) of the middle lamellae but also of the cell walls. This work, which proposes for the first time an in-situ investigation of the dynamic temperature evolution of the flax cell wall properties, evidences the reversible behaviour of their crystalline structure (i.e. cellulose) and local mechanical properties after cooling to room temperature, even after exposure to high temperatures.
