The recent introduction of new Cannon technologies for the manufacture of Epoxy-based composites found an overwhelming response from the market.
In addition to a significant number of low-pressure dispensing machines sold for the impregnation of the giant blades used for the eolic generators industry, Cannon have introduced three different impregnation systems based on high-pressure technology.
A whole range of solutions is now available to respond to different needs and processes. Cannon supplies today the widest set of tools, including dispensing and mixing devices, preformers, presses, moulds, manipulators, ovens and controls. Exactly two years ago, at Jec 2010 in Paris, Cannon launched their new high-speed RTM technology for Carbon-reinforced composites based on Epoxy resins.
The new process, called ESTRIM (Epoxy Structural Reaction Injection Moulding) was making possible the industrial use of new, fast reacting Epoxy formulations developed to comply with the high productivity required by the automotive industry for their rising number of structural composite parts.
Based on a series of integrated products - Carbon reinforcement handling systems, dedicated preformers, high-pressure dosing unit for Epoxies, multicomponent mixing heads with different distribution methods, polymerisation presses and relevant handling systems of preforms and moulded parts - the ESTRIM process immediately received a positive response from the industry. The possibility to cut almost by ten the curing time of a large moulded part - going from a traditional 30 minutes cycle of conventional RTM down to 3 minutes with ESTRIM - appealed OEMs and Tier 1 companies.
New Solutions Are Now Available
The intense exchange of experiences matured during these visits stimulated the development of new methods for distributing the liquid Epoxy resins in the Carbon preforms. In addition to the ESTRIM RTM fast injection technology, Cannon have developed two alternative methods for the impregnation of these more or less flat mats, both to be applied in open mould prior to the closing of the press:
