The largest carbon fibre reinforced civil structure in the world; the mataf consists of two walkways. The outer ring stands 13 metres high whilst the lower second ring stands 4 metres high.
Each ring is approximately 12 metres wide. The two rings and access ramps cover an overall area of 7500m2.
The floor panels for each ring are manufactured from a carbon epoxy laminate with a structural foam core. The surfaces are then covered with sintered glass. The beams that structurally support the floor panels are also carbon epoxy reinforced parts.
The ceiling panels of each ring are moulded into decorative patterned panels using the same epoxy foam sandwich/carbon reinforcement construction. Each panel is also embedded with LED lighting.
All panel moulds are milled to the greatest degree of accuracy using the Premier Composite Technologies 5 and 6 Axis milling machines to ensure all design joints are 100% accurate to the nearest millimetre for optimum load resilience.
Overall the two rings are structurally supported by a total of 72 carbon tubular pillars. Built entirely out of carbon fibre using a filament winding process, the epoxy/carbon structures are up to 13metres tall, with the largest weighing only 1.5 tonnes.
All the structural elements including the columns are manufactured from carbon fibre composite materials.
A total of 400 tons of carbon fibre composites has been used, which makes it the largest carbon fibre reinforced civil structure in the world.
The structure is designed to accommodate up to 35,000 people.
