Carbon fiber and SIGRAFLEX® sealing materials in boat and ship building

Contact 0

In yacht and boat building, lightweight construction, longevity in water, resistance to shaft impacts and higher speeds are particularly important.

The ship building industry makes high and varied demands on sealing materials, no matter if those are about dimensions, seawater resistance, longevity or reliability.

Our high-quality materials based on carbon fibers make components considerably lighter and yet more resilient. They can withstand extreme conditions of the seas. Yachts with carbon composite reinforcement can thus be sailed faster and with less effort. We have extensive know-how in the field of fiber composite technology and offer the entire range of carbon composite products required in yacht and boat construction ranging from continuous carbon fibers and textiles to pre-impregnated and thermoplastic materials.

The SIGRAFLEX HOCHDRUCK sealing sheet meets the highest demands for sealability, making gaskets extremely safe and reliable. This is possible due to our unique HOCHDRUCK technology, creating a high-strength, adhesive-free composite of graphite and stainless steel foils.

The sheet is also available in a TA Luft compliant PRO version. Standard sheet dimensions are up to 1.500 mm x 1.500 mm (59” x 59”). For larger gasket diameters two-layer structures with segmented sections and staggered joints are recommended.

SGL Carbon's SIGRACOMP components made of carbon fiber reinforced plastics (CFRP)

SIGRACOMP^® CFRP Components

In high-tech applications requiring high strength and stiffness combined with light weight, our carbon fiber-reinforced plastic (CFRP) components are indispensable. The properties of CFRP materials bring to bear precisely when other materials reach their limits. CFRP is considerably lighter than aluminum or steel, while being extremely durable.

SIGRAFLEX UNIVERSAL Sealing Sheet and Gaskets

SIGRAFLEX^® UNIVERSAL and UNIVERSAL PRO

SIGRAFLEX UNIVERSAL and UNIVERSAL PRO are adhesive-free gasket sheets. They are made from SIGRAFLEX flexible graphite foil reinforced with tanged stainless steel. The sheets are impregnated to reduce leakage and improve handling. In addition, the PRO version complies with TA Luft leakage requirements for all sheet thicknesses.

Carbon fibers and their composites

Our carbon fibers as well as our textile, pre-impregnated and thermoplastic fiber composite materials are ideal for producing stiff, strong and ultra-lightweight components for demanding high-tech applications.

SIGRAFLEX: Long-term stable and reliable

Our SIGRAFLEX sealing materials made from expanded flexible graphite and our SIGRAFLEX packing yarns have proven their long-term stability and reliability for various demands even under extreme operating conditions.
