British architecture firm Asif Khan (London, U.K.) has unveiled three carbon fiber entry portals created for the Dubai Expo 2020. The 21-meter high lattice gateways are positioned on bridges spanning roads leading to the expo site. They are woven from carbon fiber ribbon using a 3D weaving process where the carbon fiber is wrapped around a rotating arm.

The entry portal design is based on mashrabiya, a traditional Islamic architectural latticework used to shade windows and balconies. The lattices cast intricate patterns of shadows, creating a dappled lighting effect. 

Each mashrabiya portal is 30 meters long and 21 meters high and is made up of carbon fiber lattice columns that are bolted onto the bridges.  Each has 10.5-meter high doors that welcome visitors, representing, as stated on the Expo 2020 website, “a symbolic act of Expo 2020’s doors being literally thrown open to the world.”
