Development of Bio-Based Self-Reinforced PLA Composites

Abstract:

Self-reinforced polymer composites (SRPCs) are receiving increasing attention by the industry for lightweight applications. The polymers used for SRPCs today are derived from fossil resources. However, due to a limitation of resources, interest is growing regarding the use of new alternatives for petrol based polymers in form of bio-based ones. SRPCs combine high stiffness, high impact and high durability with impairing recyclability. In SRPCs the same polymer is used for the reinforcing and matrix phases. SRPCs can be manufactured by commingling reinforcing and matrix fibres with different melting temperatures. The use of commingled yarns allows the combination of a large variety of fibres and therefore a wide range of material properties.
