Location-Dependent Mechanical Properties of In Situ Polymerized Three-Dimensional Fiber-Metal Laminates

Abstract:

The formability of fiber-metal laminates (FML) produced in autoclave process is limited due to processing restrictions. In addition, the industrial application of these hybrid laminates is usually unattractive, as the production time leads to high production costs. A new manufacturing process has been developed, which combines the deep-drawing process with a thermoplastic resin transfer molding process (T-RTM). Three-dimensional sandwich components were produced. They consist of 1 mm DC04 steel face sheets and a varying number of intermediate layers of thermoplastic reinforced glass fiber fabrics. Due to the manufacturing process, the mechanical properties differ locally depending on the location-dependent degree of sheet metal forming and the location-dependent fiber draping. The mechanical properties are therefore investigated by three-point flexural tests on miniaturized samples in order to map these location-dependent properties.
