SMTC has developed Dynatech, a thermoplastic sandwich panel system specifically for the use in applications that require damage tolerance and superior fire, smoke and toxicity (FST) values.
According to SMTC, due to its thermoplastic nature as a ready-to-be formed sandwich system for mass production, Dynatech can be used for the manufacturing of various complex shaped parts in the interior of aircrafts and trains, like seats, luggage or overhead-bins.
Based on a PEI in-situ foamed panel, Dynatech is described as offering better thermic and acoustic isolation compared to traditional honeycomb based on thermoset panels, which will in the end also contribute to the traveller´s comfort.
Christophe Jenny, CEO of SMTC commented “With Dynatech, we proactively made a major investment in mass-production with high repeatability in order to better serve our customer´s needs regarding significant weight savings, better mechanical properties, lower total system costs and recyclability. We see ourselves as a carrier for solutions that fulfill the society´s needs and thus are happy to contribute to the reduction of CO2 emissionand to the performance of mass transport and the comfort and accessibility of its passengers.”
SMTC claims that Dynatech´s automated production guarantees higher quality standards and control possibilities which it says is highly appreciated by the OEMs. Due to the patented closed-box procedure, this system allows for sophisticated design of the edge close-out which actually becomes the strongest part of the system. In that way, Dynatech claims a total system cost reduction of up to 20-30% , beside the weight reduction of 20-40%.
Dynatech can help generate new design opportunities for that the aircraft and train builders can use thinner layers of sandwich material, which will ultimately lead to more space for the travellers. Its unique heat resistance properties make Dynatech a highly desirable and long-lasting material to be used for the interior.
Martin de Groot, CEO of FITS Technology and inventor of the process, reveals what gave him the idea of this invention, “My goal was to achieve a maximum weight reduction for improving the ecological footprint of aircrafts. In comparison with traditional sandwich systems, Dynatech is much less labor-intense through its automated processing. Dynatech now allows for extremely short cycle times for pressing of only a few minutes and it outperforms the traditional material also in offering a manufacturing time of maximum 30 seconds per edge. I am very proud that thanks to AMAC, who handled the trade with SMTC, Dynatech will now go for mass production and my life work will be achieved.”
The production of pilots has already started, qualifications are running and the first customers have received prototypes.The full commercial production will be ready in 2016.
Michael Effing, Founder and CEO of AMAC, explains “It is a big pleasure for me to drive innovation and this is an excellent achievement for the development of the overall thermoplastics trend in the industry. Dynatech panels, with their feature of being suitable for automated mass-production, will certainly contribute to the further market growth of highwage-countries in Europe, like Germany and France.”
