Thermoplastic sandwich composites with honeycomb core made of polyamide

Lanxess and EconCore are joining forces to develop thermoplastic sandwich materials for lightweight construction.

The objective of the collaboration is to fabricate honeycomb cores from Durethan polyamides with the help of an automated, continuous process patented by EconCore. In addition, Tepex continuous fiber-reinforced thermoplastic composites from Lanxess subsidiary Bond-Laminates are to be combined with the new polyamide honeycomb cores to produce high-performance composites.

Lightweight construction with Tepex
Polyamide honeycomb cores, and the sandwich composites in which they are incorporated, open up entirely new possibilities in lightweight construction, for instance of high load-bearing structural automotive parts. This applies in particular to composites with Tepex facings.

Major increase in strength and stiffness
Thanks to their set of properties, high-tech Durethan polyamides lend the honeycomb cores very high stiffness and strength even at relatively high temperatures, and good thermal aging resistance. Combining the honeycomb cores with Tepex facings, for example, results in sandwich composites that raise performance another notch in terms of strength and stiffness.

EconCore is a producer of economic honeycomb sandwich. Its ThermHex technology allows producing honeycomb cores and sandwich panels in a fast, continuous, in-line process. Due to its high efficiency ThermHex technology is applied typically in mass market applications allowing reductions of product’s cost and weight and consequently reductions of CO2 emissions.

Lanxess is a specialty chemicals company with sales of EUR 8.3 billion in 2013 and roughly 17,300 employees in 31 countries. The company is currently represented at 52 production sites worldwide. Its core business is the development, manufacturing and marketing of plastics, rubber, intermediates and specialty chemicals.
