SANDWICH PANELS AND LAMINATES lightweight & superstrong

EFW´S SANDWICH PANELS are made from two main elements: glass and carbon fibre layers or metallic sheets as skin and a core. Due to spe-cific customer requirements we use for the core different materials: e. g. honeycomb, foam or glass.

EFW´S CFRP/GFRP LAMINATES are made from combinations of woven or uni-directional oriented glass or carbon fibres in a duroplastic matrix. Laminates are manufactured under cleanroom conditions.

GENERAL CHARACTERISTICS

› Lay-ups made from glass and carbon fibre or metallic skins and NOMEX® / KEVLAR® honeycomb or other core materials

› Lay-ups & core arranged in a modular system for optimal sandwich lay-up design

› Various decors depending on application: tedlar, decor foils, gloss and texture coatings

› Flexible geometries and in-sandwich design features

› Deliveries just in sequence ready for assembly

› Max. size 2,90 m × 1,88 m, maritime panel: up to 1,20 m × 2,70 m

› Design of integrated systems including attachment parts

› From semi-finished panels up to drop-in panels

MAJOR PRODUCT FEATURES

› High strength and stiffness combined with minimized weight

› Low smoke emission and toxicity

› Resistance to environmental factors such as humidity, vibration, sand and liquids

› Fire resistance and low flammability
