Prepreg


PRF manufacture and supply a comprehensive range of prepreg materials in woven carbon fibre, glass fibre, aramid fibre, hybrids, unidirectional carbon and glass fibres, as well as prepregs with carbon nanotube additives. The resin content of each layup, epoxy or phenolic, can be manufactured to suit your unique requirements.

In 2013, we completed installation of our new prepreg line, now manufacturing at our headquarters in Poole, Dorset. Expanding on our current prepreg service, the new line has a capacity of over 1 million linear metres p.a. at 1.5m wide and is fully capable of processing large quantities as well as small runs of speciality materials, such as Dyneema®, for innovative and bespoke applications. The service benefits greatly from our experience in fabric development and R&D facilities, allowing us to produce unique and technically advanced products.

Our manufacturing capabilities include both solvent dip and hot melt processes, with a range of materials, including woven fabrics, UD prepregs, and multiaxials in a range of fibre types. We can also provide prepregs with carbon nanotube additives, resin films and adhesive films.

Our prepreg line is fully supported by the latest technology, such as film weight scanning technology, chemists and our extensive laboratory facilities. Representing a vast development for PRF, in 2013 we extended our process laboratory to incorporate resin development and R&D, and introduced a new material testing laboratory which can perform thermal analysis and mechanical testing for R&D and quality assurance.

Technical after-sales support will be available and standard lines will be kept on stock in the large freezer facilities at our headquarters, ready for immediate despatch. Providing a full service, we are able to cut a wide variety of prepreg  on our CNC cutting machine; we accept two-dimensional CAD drawings via email and nest for optimum material usage.  Kits are supplied in bags ready for use.

Innovation at PRF:

2015: Following the successful launch of PRF’s RP-570 Snap Cure system, which provides an aesthetic class finish to pressed components with a complete cycle time of 4 minutes, we are delighted to introduce our new RP-801 and RP-802 tooling prepreg systems. Developed to offer you the choice of system that best suits your processing and manufacturing requirements, PRF’s new RP-801 offers a high quality, industry-standard tooling system, with a cure cycle of 8hrs at 60°C and a tack life of 5 days (at 20°C). RP-802 Overnight Cure offers double the tack life (10 days at 20°C) with a 16hrs cure at 60°C or 8hrs at 70°C. Both systems have a Tg of 190°C after post cure. Contact our team for more information: enquiries@prfcomposites.com

2014: You can now buy selected products from our prepreg materials range on the PRF Online Store. Visit to browse the range of low temperature and mid-temperature systems available.
