Nidaplast Honeycombs, specialist in extruded polypropylene honeycomb, is offering a new range of honeycomb materials for infusion moulding.
“Research conducted in 2006 has led to a new possibility for combining infusion technology with honeycomb properties,” says Marketing and Development Manager Richard Filippi. “As compared to lamination techniques, the combination of honeycomb with infusion moulding results in improved mechanical properties through higher glass contents and optimised sandwich properties,” he added.
A thermobonded reinforced plastic film makes the honeycomb impermeable to the resin, and resin flow in the mould is optimised through the addition of a specially selected interlaminar flow medium on each side of the honeycomb. This flow medium generally remains within the structure.
Thanks to the infusion process (already in widespread use with hand lay-up and spray-up techniques for all types of short- and medium-run production series), “honeycomb can now be used for large parts at the industrial scale,” Richard Filippi comments. “This opens up new applications, allowing the production of a wide range of parts and tooling for the marine, wind energy, and equipment industries, whatever their size”.
The environmental credentials of battery electric vehicles were questioned at the latest Future of Technology seminar organised by the Advanced Propulsion Centre (APC) and Innovate UK.
Scigrip has expanded its agreement with Biesterfeld Spezialchemie to include France and the French territories in Northern Africa, with immediate effect.
