Abstract:

Research was conducted to determine the basic dynamic properties of fiberglass-reinforced plastic FRP sandwich structure suitable for use as a primary airframe structural material. The research program was carried out in two separate parts A determining dynamic moduli and damping, and B determining fatigue behavior. In each part, two types of hexagonal cell honeycomb core materials were investigated 5052 aluminum foil and HRP heat resistant phenolic fiberglass.
