What is Glare?What is Glare?

GLARE is a new aerospace structural material composed of GLARE is a new aerospace structural material composed of alternating, bonded layers of aluminum alloy and glass fiber alternating, bonded layers of aluminum alloy and glass fiber reinforced plastic.reinforced plastic.

GLARE looks the same as aluminum sheeting, but it is GLARE looks the same as aluminum sheeting, but it is constructed from layers. First a thin layer of aluminum, then a constructed from layers. First a thin layer of aluminum, then a thin layer of strong fiberglass, and then another layer of thin layer of strong fiberglass, and then another layer of aluminum.aluminum.

The material thus obtained combines the properties of both The material thus obtained combines the properties of both the metal and the fiber.the metal and the fiber.

The metal makes it possible to deform GLARE plastically, The metal makes it possible to deform GLARE plastically, while the fibers give GLARE strength. while the fibers give GLARE strength.
