Polymer & Composite Processing (PCP)

PTG

INTRODUCTION

TThe Polymer & Composite Processing Group (PCP) develops near net shape polymer and composite processing technologies, including functional property enhancement, design optimisation and process customisation. The aim is to create dimensionally accurate parts with optimised mechanical properties, while minimising material wastage and manufacturing costs within the process chain.

The group carries out collaborative cutting-edge research with academic institutions, co-develops processes and products with companies, transfers technology and conducts training for the manufacturing industry. PCP welcomes industry partners and industry-minded academic collaborators to work together on innovative research, and process and product development through projects and joint laboratories.

Focus Research Areas: 

  • Near-Net Shape Polymer & Composite Processing Technologies
  • Functional Property Enhancement 
  • Design Optimisation & Process Customisation

RESEARCH HIGHLIGHTS

New design and test capabilities towards multi-material hybrid composite part development:

A universal joint utilising carbon fibre reinforced thermoplastic composites with embedded metal inserts was achieved through FE design optimisation of the insert base profile, experimental evaluation of surface treatments and laminate strength, and the development of tool designs and process concepts that supports the fabrication of high-quality parts. Given the right design and process prescriptions, lap shear strengths of greater than 80% was retained at the metal composite interface after 100 thermal cycles.
