This approach leverages the inherent properties of fiberglass reinforced polymers (FRP) to meet the structural requirements of the aircraft while minimizing weight.

Fiberglass Types Employed

The specific types of fiberglass used in the prototype are critical for determining its performance characteristics. High-strength, high-modulus fiberglass reinforced polymer (FRP) materials, such as E-glass and S-glass, were likely chosen for their tensile strength and stiffness. These properties are essential for withstanding the stresses encountered during flight.
