Eurocomb core material might be aluminum, meta-aramid (Nomex), polypropylene, paper, etc.
Eurocomb is a metallic, light-weight honeycomb material mainly applied as core material in sandwich composite constructions, but also in other applications as for example shock absorbers, flow directionalizers and water jet cutting equipment. For the production of this core chromated aluminum foil is used in a thickness of 80 µm and 60 µm. Eurocomb-core exhibits high strength-to-weight properties as well as excellent thermal and electric conductivity. Aside from this, Eurocomb is corrosion and heat resistant. These properties make Eurocomb an ideal construction material in light-weight construction and an optimal base plate for water jet cutting.
Availability of Eurocomb
The standard programme of “11Oktomvri-Eurokompozit” comprises composites based on the following Eurocomb types:
Eurocomb 4.8-77
Eurocomb 9.6-55
Eurocomb 6.4-60
Eurocomb 12.7-42
Eurocomb 6.4-82
Eurocomb 19.2-29
Eurocomb 6.4-82 for example describes an aluminum core type with a cell size of 6.4mm and a density of 82kg/m³. Delivery of core types with other cell sizes and/or densities is available upon request.
The largest available dimension is:
length (W) : 2500 (±100) mm
width (L) : 1250 (±50) mm | |
Core thickness (T) of between 2 (±0.20) mm and 300 (±5) mm according to customer requirements are readily available. Aluminum core of other dimensions may be applied upon request.
>Eurocomb composites are produced in different thickness and in various skin materials.
