Abstract
The article presents modern laminate composites designed for aircraft structural elements based on ECC e461 symmetric fabric and Interglas 02037 symmetric fabric with MGS L285/H285 resin. These composites differ in the weave used and the type of fabric. The article presents basic strength parameters of the composite obtained as a result of stand tests. The results of compressive strength tests of the material samples are presented. It was shown that the weave of the fabric significantly affects the strength parameters of the composite. The change of the weave caused the increase in strength by more than 65%. The possibilities of application of this material on selected structural elements of aircraft such as: propeller blade plating, masts, shavings, pylons.
Highlights
Aircraft structures in their construction use materials characterized by high strength and low weight
Composite materials take over from aluminium alloys a key position in the aerospace industry
The paper presents the results of compressive strength tests of a new composite material carried out with the use of manual lamination method based on the above fabrics
Summary
Aircraft structures in their construction use materials characterized by high strength and low weight. Composite materials commonly used in aircraft are based on a matrix made of: glass fibre, carbon fibre, fibre-reinforced matrix systems or any combination of them [9,11] These materials were used, among others, in the production of rotor blades, load-bearing elements of the airframe structure, hulls, shields, etc. The manufacture and use in industry requires gaining knowledge about the influence of particular components and methods of manufacture on the final properties of the composite [4,10]. This is important when new constituent materials appear. The paper presents the results of compressive strength tests of a new composite material carried out with the use of manual lamination method based on the above fabrics
