Advanced Polymers and Composites (Apc) Research Group

Our activities include research and development into design, creation and testing of polymers and composite materials, and analysing their effectiveness. We also investigate modelling, 3-D printing and structural integrity of sustainable biocomposites.

Our research informs teaching and knowledge transfer activities in the School of Mechanical and Design Engineering and Faculty of Technology. We contribute to the international research profile of the ��ý through high-quality publications and participations.

Our mission is to build modern work in advanced materials and manufacturing, through collaborative partnerships with industry and other partners.

Research

Advanced composites application driven areas

Composite materials (natural fibre composites and biocomposites for light weight applications)
Conventional composites and nanocomposites
Polymers/plastics (thermosets and thermoplastics)
Composite manufacturing (aimed at exploring the link between materials, process and performance)
Additive manufacturing (Design and rapid prototyping, 3D printing of polymers and composites)
Lean manufacturing

The APC research group has well-equipped laboratories with facilities for R&D in advanced polymers and composites. The activities we undertake range from short-term consultancy works to medium-to-long-term research and knowledge transfer projects.

SeaBioComp

The FLOWER Project

Successfully completed June 2023

Flax used as alternative manufacturing material

We're working with partner organisations in the UK and France on an innovative research project to develop natural fibre composites that are a viable alternative to the non-recyclable fibreglass products widely used in the automotive and marine industries.
