Development and manufacturing of sustainable composite materials

A key focus of this programme is to increase sustainability of composite materials, their manufacturing processes and the products made with them, and ultimately, the businesses that use them.

The international market for composite materials is rapidly growing due to their use in the air, land and sea transport industries as well as packaging, medical applications, physical infrastructure and sporting equipment.

Key focus areas/issues


This programme has five inter-related technical objectives:

  1. Polymer composites using nano- and/or micro- reinforcements with emphasis on biomedical applications.
  2. Advanced manufacturing processes to reduce cost and energy usage.
  3. Enhanced durability of products and structures.
  4. Development and evaluation of functional composites with fire retardant and self-healing attributes.
  5. Design of sustainable composite systems and product development using natural renewable resources, incorporating life cycle analysis of composite components and processes.

Current major developments


cl-imm-sustainable-composites1
  • A novel technique has been developed to produce single polymer composites using our fibrillar composites manufacturing technology.
  • Hollow sandwich panels have been manufactured and tested using core geometry optimisation methodology developed at the Centre for Advanced Composite Materials.
  • Natural fibre reinforcement has been successfully used in rotational moulding of foamed products and the technology has been patented for market release. Super strong (and stiff) biodegradable composites, reinforced by flax, have been produced using a novel technique we have developed.
  • A novel binding technique using waste polymers has been developed and patented.
