Surface Generation, a provider of advanced carbon fibre<\/a> processing technologies, is working with WMG, an academic department of the University of Warwick, and special materials provider AGC AeroComposites <\/a>(AGC) to develop new composite press-forming processes for automotive and aerospace manufacturers.<\/p>\n

Surface Generation<\/a> is an advanced materials processing company based in the Midlands, United Kingdom. Its patented \u2018Production to Functional Specifications\u2019 (PtFS) process is used to combine, compact, process and meld plastic, glass and composite materials far more efficiently and with much greater precision than is possible using traditional injection and compression moulding processes. Surface Generation\u2019s technologies are used by component providers and manufacturers across a range of industries, including aerospace, automotive, consumer electronics, defence and leisure.<\/p>\n

Surface Generation\u2019s PtFS process provides significantly greater regional control than traditional autoclave and oven curing. It also out-performs other methods across a range of temperature, cycle time and energy consumption metrics.<\/p>\n

Uniquely in PtFS, the specification of the target component is used to precisely engineer the thermal, structural and control characteristics of its mould tool. Tools can be designed such that mould temperatures can be dynamically controlled to the exact requirements of individual regions or zones in a part and progressive stages of the forming and curing process. The tool is divided into multiple regions (typically >32) which are connected to a multi-channel control system. Variable, on-demand heated & cooled fluids circulating through each region allows individual zones to be independently managed throughout the entire cure. Pre-emptive control strategies programmed into the system ensure the final part meets its ultimate design intent.<\/p>\n

Isolation and individual control of these regions enables manufacturers to continuously, and very rapidly, adapt each zone\u2019s heating and cooling levels in real-time, optimising part quality and maximising throughput.<\/p>\n

The company is developing new press-forming mould faces incorporating its patented PtFS technology for the production of high-performance thermoplastic composite components. By integrating Surface Generation\u2019s active thermal management technologies into the mould face itself, WMG and AGC are able to continuously adapt heating and cooling levels for each mould area and process stage in real-time, with the expectation of improving both the quality and throughput of compression moulding.<\/p>\n

The work is in support of the Composites Innovation Cluster\u2019s Thermocomp project, which is seeking to develop short cycle time, high volume manufacturing processes that can be used by automotive and aerospace manufacturers for producing carbon fibre-reinforced thermoplastic components.<\/p>\n

Ben Halford, Chief Executive at Surface Generation, comments: \u201cPtFS provides automotive and aerospace manufacturers with a new level of sophistication in compression moulding. The ability to dynamically control the heat applied to each mould area throughout the cure cycle means manufacturers can quickly and cost-effectively upgrade existing production lines for thermoplastic composites and significantly reduce their cost of production. As part of an integrated production line PtFS makes it possible for manufacturers to achieve one minute Takt times for thermoplastic components.\u201d<\/p>\n

WMG was founded by Professor Lord Kumar Bhattacharyya in 1980 to help reinvigorate UK manufacturing. The Group has grown into an international role model for how universities and business can successfully work together, with Bhattacharyya continuing to lead as Chairman. WMG has over 500 people working across six buildings on the Warwick campus, plus collaborative centres in seven countries.<\/p>\n

Geraint Williams, Project Manager at WMG, comments: \u201cA major barrier to mainstream adoption of novel, aligned fibre-reinforced thermoplastics within the automotive sector is the difficulty of economically achieving short cycle times within a high volume production environment. Surface Generation’s PtFS technology has the potential to meet this challenge by eliminating process stages and enabling manufacturers to rapidly form composite components using a one-shot stamp-forming process.\u201d<\/p>\n

Dave Conway, Materials Technology Director at AGC AeroComposites, comments: \u201cTraditional press forming processes are not economically viable for producing even medium volume parts of complex shape. By incorporating its revolutionary PtFS process into conventional press forming processes, Surface Generation has opened the door to a very exciting new era in aerospace manufacturing.\u201d<\/p>\n
