Glass Fiber Reinforced Polymer (GFRP)

Glass-fiber reinforced structural composite.

Core Principles & Analysis

• E-glass, the most common reinforcement fiber, was originally formulated for electrical insulation, which is what the 'E' stands for.
• GFRP is nearly transparent to radio waves, so it is the standard skin material for radomes that shield radar antennas.
• Modern wind turbine blades exceeding 100 m in length are built primarily from glass-fiber composite.
