Prepregs and composite materials made of aluminium alloys reinforced with continuous fibers

Objective

The aim of the project is to investigate advanced aluminium matrix composites, obtained via the prepreg route, for applications in aerospace structures (C/Al) and heat engines (SiC/Al). The programme envisages four steps: Prepreg-processing, C (HM or UHM) Al and SiC (NICALON-type/Al). Characterization of the prepregs. Composite processing. Characterization of the composites.
For a unidirectional laminate, one of the newly developed composites, FT700/Al, had: the best mechanical properties; the best tensile strength of about 600MPa; a fibre volume fraction of about 45%; a Young's Modulus of 270GPa; a transverse strength of 30MPa; and a density of about 2.3a/cm{3}.
