Nidaplast composites has developed its nidaplast 8RI polypropylene honeycomb core material for structural sandwich panels up to 90 mm thick.
In combination with an infusion process, Nidaplast says that this polypropylene honeycomb is a cost-effective solution for manufacturing extra-thick sandwich structures in which part stiffness is achieved without adding extra weight. The cells are leaktight, thanks to a plastic film that resists the pressure of the resin, and resin flow is ensured by an interlaminar flow medium.
“We were the first to start producing large parts using a technique that combines honeycomb and infusion for thicknesses from 10 to 30 mm. We are now extending the applications for our innovation to extra-thick parts up to 90 mm. Because of its specific structure, the nidaplast 8RI polypropylene honeycomb is the most technically cost-effective material for creating extra-thick self-supporting composite parts. Standard cores, such as one-piece wood or PVC foam, can be very expensive in very thick parts, whereas the price of honeycomb does not increase linearly,” said Luc Nuttens, Development Engineer at Nidaplast composites.
Nidaplast anticipate that the field of honeycomb applications will now become much broader, especially in the marine or wind-energy industries in applications such as wind-turbine nacelles and boat superstructures.
TRB Lightweight Structures has recently gained the highest DIN 6701 (Parts 1-4) A1 type certification.
Composite products, based on polyurethane technologies from global chemical company Huntsman, are taking centre stage at a design exhibition at the Design Museum Gent, Belgium.
In late November, the 14 project partners in the MoPaHyb consortium developing a modular production plant for hybrid high-performance components wrapped up their successful efforts with a two-day symposium in Pfinztal, Germany.
