Gurit introduces in their April 2020 Marine Newsletter, that the marine industry can save weight when using their Corecell material for forming curved panels on an adaptive mold.

(Aalborg, Denmark) supplies adaptive, robotic molds for the manufacture of curved surfaces and has already used its technology to  thermoform Gurit (Wattwil, Switzerland) Corecell foam in full-scale production of lightweight marine vessels.

Gurit engineers have worked with thermoforming expert (Zoetermeer, Netherlands) to demonstrate the Adapa adaptive mold technology. As described in the April 2020 issue of ,  the team, using 30-millimeter-thick Corecell M100 thermoformed to a 1200-millimeter radius, found the material had a similar resin uptake to a flat plain sheet. This means a 73% resin saving is achieved in comparison to doing the same with single cut foam and 138% saving compared with contour scrim foam. Dynamic testing of the thermoformed core also confirmed that it was able to absorb the same level of dynamic energy as the virgin material.  Based on these results, Gurit suggests thermoformed Corecell M foam is the process and material of choice for forward slamming areas that are typically curved.

This technology was demonstrated at the Compotec 2020 event held in February in Italy. There, Gurit’s distributor Resintex showcased how to thermoform curved Corecell in cooperation with Curve Works, using a demonstrator mold system contributed by Adapa. The team discussed that this approach provides not only lighter weight ship construction but also cost savings due to reduced resin usage and waste.
