Sigrafil C T50-4.9/235 carbon fiber has strength of 4.9 GPa and elongation of 2%, which previously could only be achieved with lower filament count fibers such as 12k or 24k, the company said. They can also withstand pressures of up to 700 bar when used in the pressure vessels.
"Carbon fiber-based solutions are a key driver for the transformation to sustainable mobility, for example in pressure vessels for future hydrogen mobility and fuel cells,” said Roland Nowicki, head of business unit carbon fibers at SGL Carbon.
SGL says that the material can also be used in industries such as construction, infrastructure and sports that require high strength and fiber elongation.
