EconCore has introduced a new range of honeycomb cores for laminated sandwich panels that it says has a higher heat performance, better dimensional stability and lower water absorption compared to honeycomb structures made with traditional thermoplastics.

The honeycomb cores are made with made with Sabic’s Noryl GTX resin, a polyphenylene ether (PPE) blend. Sabic is also developing a new grade with extreme low-temperature impact performance for potential use in honeycomb cores for electric vehicle (EV) battery protection.

The new core material to can be used in applications such as automotive, e-mobility and photovoltaic components, and combined core with thermoplastic composite skins to produce an all-thermoplastic sandwich panel can facilitate recycling, the company said. Sandwich panels made solely with thermoplastics can also be more efficiently processed into finished parts with complex geometries using compression molding processes, which can help reduce cycle times.

According to EconCore, the honeycomb may also be used in lamination with thermoset prepregs in processing environments where high curing temperatures are typically applied. The honeycomb can also potentially be used for applications where sandwich panels can cope with elevated temperatures.
