Abstract:
Natural fiber reinforcements have garnered significant interest in the composites industry due to their specific mechanical properties and environmental benefits. Natural fibers, such as flax, offer an abundantly available, sustainable, biodegradable, and economically viable alternative to synthetic fibers like carbon and glass. The increasing demand for composites in automotive, aerospace, and defense industries, which require lightweight and high-strength materials, underscores the importance of this development. Additive manufacturing (AM) techniques based on photocuring, such as digital light processing (DLP), provide high resolution and are suitable for UV polymerization of thermosets. This study aims to produce samples using an acrylic photopolymerizable resin matrix with varying flax fiber mass fractions of 0%, 1%, 1.5%, 2%, and 2.5% through the DLP process. These materials will be subjected to density tests to evaluate their properties. The results will contribute to understanding the potential of flax fibers to rival synthetic fibers, especially glass fiber, in developing more sustainable composite materials.
