The Cyclics Corporation have produced low pressure castings and high fibre content thermoplastic composites through the RTM process for its CBT(R) resin one-part system.
CBT resin and catalyst are combined in a ""one-part system,"" simplifying the process by eliminating the need for meter mixing equipment. Cyclics has worked with Radius Engineering to produce parts using both their pressure and flow control injectors.
Capitalizing on the water-like processing viscosity of CBT resin, the RTM process allows the production of low pressure cast parts and high fibre content thermoplastic composites. Parts produced are lightweight, and said to have improved damage tolerance, high stiffness, and high mechanical strength. Since the resins are thermoplastics they can also be thermoformed and recycled. Developments are ongoing for sports equipment, wind turbine blades, automotive and industrial parts. This development also opens the door for low pressure moulding of traditionally injection moulded thermoplastic parts.
""We saw the potential of Cyclics' products from the time we fabricated prototype structural auto parts from the initial resin formulation in 1996. Now that Cyclics has developed a new one-part system, the processing is very user-friendly. Because of CBT resin's extremely low viscosity, we believe that even larger, more complex parts can be injected in 60-120 seconds, with very high quality"", said Dimitrije Milovich, President of Radius Engineering, ""Pairing our RTM injector system expertise with Cyclics' exciting new resin technology gives Radius a strong entry point into the growing thermoplastic composites market.""
""The quality and variety of parts we can make using inexpensive RTM equipment will enable our customers to create high performance thermoplastic parts,"" said Martin Roesch, European Marketing Manager for Cyclics Corporation. Mr. Roesch is presenting a technical paper on the use of CBT resin in RTM at the Society for the Advancement of Material Process Engineering (SAMPE) session co-located with the upcoming JEC Composites Show on March 31, in Paris, France.
