EconCore NV and DuPont Performance Materials have joined forces to make strong, high-temperature resistant honeycomb panels.

The panels make use of DuPont’s Zytel nylon resin and Surlyn ionomer resin materials to deliver honeycomb cores that can be more high-temperature-resistant and also tough and resilient.

The honeycomb cores are combined with skins made of Vizilon thermoplastic composite, a light, continuously reinforced fiber composite sheet based on a high-temperature-resistant, heat-stabilized polyamide matrix. In various configurations, the honeycomb cores can maximize stiffness and strength at a minimal weight, with dimensions never achieved before, the companies say.

‘EconCore’s ThermHex technology for continuous production of sandwich panels with thermoplastic honeycomb core has proven to be capable of delivering high-performance sandwich panels at high efficiency and cost levels not achievable for conventional methods,’ said Tomasz Czarnecki, technology manager at EconCore NV. ‘Within the in-line integrated ThermHex technology, Zytel based honeycomb core can be welded with the Vizilon thermoplastic composite, delivering sandwich panels with a very stable core-skin interfacial connection.’

Possible applications

‘We also are looking at making honeycomb panels with dissimilar materials, using EconCore continuous process in combination with special high-temperature thermoplastic adhesives, such as DuPont Elvamide, offering a wider range of possible applications for the skin-core combination,’ added Fabrice Giaume, technical programs leader for DuPont.

According to the two companies, the transportation, construction, leisure and energy segments could be potential applications for the honeycomb panels.
