Abstract

A description how to create fiberglass for tail section skins of helicopter rotor blades instead of the currently used skins of organic textolite is provided. In order to make the skins it was decided to use unidirectional prepreg and two layers of glass textileforming in autoclave a monolith plastic with fixed binder content.. A selection of optimal reinforcement scheme from two options is executed. Bench test results showed that at the chosen reinforcement scheme the fiberglass plastic has high strength characteristics, endurance crack resistance and meets all the requirements for the tail section skins of helicopter blades.
