Development of Green Composite Structures Dr Stuart Coles and Dr Kerry Kirwan Composites are used in today’s society for a wide range of applications, particularly those where specific stiffness or strength are required. Commonly used reinforcements include glass, carbon and aramid fibres; all of which pose problems in today’s sustainable society. Both glass and carbon fibre are energy-intensive processes and aramid fibres require extensive and wasteful chemical treatment. Natural-fibre reinforced composites (NFRCs) present an interesting alternative to the conventional fibres but have often performed poorly when the materials properties are compared. They also still tend to be used with conventional, petrochemically-sourced resins which have a damaging environmental impact. Resins derived from natural sources are starting to become available but the nature and amount of true “bio” content remains low. The main aim of the project is to create a biocomposite made from natural fibres and bioresins sourced from 100% sustainable sources and then assess its potential uses.
