Definitions
- the invention relates to a method for producing a molded part, in particular a molded part with a first component of a metallic material and at least one second component of a fiber-plastic composite system.
- moldings for example, from the document DE 10 2013 104 635 A1, already known.
- the prior art also knows such moldings, on the one hand comprise a metallic material having a first layer and on the other hand, a fiber-plastic composite having second layer.
- These moldings are known as semi-finished products, for example, from the automotive industry and allow as a hybrid structural part, the advantageous material properties of the metal and the fiber-plastic composite, namely the lowest possible weight, for example, a desired energy absorption in the event of a crash and a relatively high strength to unite.
- the present invention solves the problem by a method for producing a molded part comprising the following method steps:
- the heated composite is formed by means of a forming tool to the molding.
- the first component comprising the metallic material and the second component comprising the fiber-plastic composite system are jointly formed in a composite, ie as a hybrid structure.
- the first component is preferably single-layered or layer-formed from a metallic material.
- the second component can be formed in one or more layers or one or more layers of a fiber-plastic composite system.
- the first component of a metallic material (sheet) and the second component of a fiber-plastic system which comprises a plastic matrix and fibers, in particular in the plastic matrix mounted fibers, already materially together are connected or in a second embodiment, the first and the second component are not yet connected to each other, wherein the connection of the first and the second component can take place before or during the forming step.
- the fiber-plastic composite system can be provided as a stored in the plastic matrix fibers (consolidated state) or on the other hand, the plastic matrix and the fibers in not yet or partially consolidated state.
- the forming process is a deep drawing. Examples of further conceivable forming processes are roll profiling, bending and / or folding.
- the first component is a metallic layer, for example a steel layer or a layer of aluminum, magnesium or stainless steel.
- a material for the plastic matrix in particular thermoplastics, such.
- PA polyamide
- PE polyethylene
- PAPE polyamide / polyethylene
- PPS polyphenylsulfide
- PSU polysulfone
- PP polypropylene
- Exemplary embodiments of the fibers in the second component are carbon fibers, glass fibers, natural fibers, aramid fibers, polymer fibers, metal fibers, ceramic fibers or mineral fibers.
- the use as short fiber, long fiber or endless fiber is also conceivable.
- the fibers are present in the fiber-plastic composite system as a fiber system.
- the fibers are present as a fiber system in the form of a mat, a fabric or a fabric.
- the method proves to be particularly advantageous because such fiber systems are particularly prone to tear under the load of a conventional forming process of the second component.
- the second component may be provided over the entire surface or partially in a composite.
