Abstract
Biodegradable composites were fabricated from poly-lactic acid (PLA) reinforced by flax braided-yarn woven fabric. Composites with different fabric content (corresponding to the 1, 2 and 3 layers of fabric respectively) were obtained by solution casting and compression moulding processes. Tensile fracture properties were evaluated using the double-edge-notch-tension (DENT) test. A scanning electron microscope was used to look at the fractographic features. Reinforcement of braided-yarn fabric resulted in enhanced tensile fracture strength (σ<inf>f</inf>) and toughness of PLA composite. Fracture toughness (K<inf>IC</inf>) of the composite improved with the fibre contents, namely 64, 79 and 89%, which correspond to 1, 2 and 3 layers of fabric. The improvement in the tensile fracture characteristics of the composites could be contributed by the presence of an effective interfacial bonding of fibre matrix. © 2023, The Author(s), under exclusive licence to the Korean Fiber Society.
