HiPerDiF: A New Route to Produce Sustainable Composites

The High Performance Discontinuous Fibre (HiPerDiF) technology is now entering its 13th year. Originally developed at Bristol within the EPSRC-funded HiPerDuCT programme grant, and subsequently patented, the method offers a more sustainable route to the production of advanced composites. An upscaled machine, owned by the University of Bristol and based in the National Composites Centre, also makes it possible to generate novel prepreg material (25 mm wide) at scales (ca. 30-50 m/run) that allow the production of larger laminates for standard mechanical tests to be performed. This has led to the launch of a spin out company (Lineat Composites Ltd.) in 2021. In this presentation, Prof. Hamerton will describe the history of the technique and concentrate on more recent developments in a variety of current research projects within the Bristol Composites Institute.
