GLARE (Glass Laminate Aluminium Reinforced Epoxy)

DENSITY: 2.52 g/cm³
YIELD STRENGTH: 310 MPa
HARDNESS: N/A

Fiber-metal laminate of thin aluminium sheets bonded with glass-fiber epoxy plies.

GLARE was developed at Delft University of Technology in the 1980s as a successor to the aramid-based laminate ARALL.
About 470 m² of GLARE panels form the upper fuselage of the Airbus A380, saving several hundred kilograms over monolithic aluminium.
Glass fibers bridge fatigue cracks in the aluminium layers, slowing crack growth by one to two orders of magnitude compared with plain sheet.
