Composite Materials and Structures.

My presentation will be on the use of Hybrid composites. These composites will be applied to small cargo aircraft for the purpose of providing lightweight construction of the outer skin of the aircraft, interior strength for loading cargo and for insulation when transporting hazardous and temperature sensitive cargo. Such examples will include Aramid composite which is a honeycomb like structure and “Rohacell” foam which is a more rigid type foam with smaller cell size. I will utilize the CAD (Solidworks) software to demonstrate how the Materials will be applied to aircraft manufacturing

Hybrid composites have a high strength to weight ratio, fire resistance qualities, corrosion resistance, and good thermal conductivity. This is appropriate when transporting hazardous materials and cargo that are sensitive to extreme temperatures. The main fuselage of the aircraft can benefit with the use of the Aramid Composite material since most of the cargo is going to be loaded in the middle of the aircraft.

The Hybrid (Rohacell) foam can be beneficial for the engine cover and for the floor interior of the aircraft. The foam can prevent excess vibrations and reduce excess noise of the aircraft. This foam structure has good strength to weight ratio and good elongation. For structural use, the foam may be more appropriate in the landing gear and floor section of the aircraft to provide extra shock absorption along with its landing gear struts.
