Nap Core is a (core) material for lightweight sandwich constructions.

Its three-dimensional nap structure is formed from a two-dimensional knitted fabric. By varying the nap geometry, yarn material, type of knitted fabric or resin system, Nap Cores can meet the demands of applications where adjustable properties are required.

Through the high variety of possible material combinations, the properties of Nap Core can be adapted to the needs of many different applications and components. The unique properties of Nap Core –  such as adjustability, drainability, drapability and easy integration of ducts and wires – enables the design of novel sandwich constructions.

Nap Core sandwich panels are suitable for applications in aerospace, aircraft, marine, automotive, railway, wind energy or design.
