Abstract
A honeycomb core having a lattice structure which includes a resin-impregnated matrix, a method for producing such a honeycomb core, a sandwich panel having such a honeycomb core, and use of such a honeycomb core or such a sandwich panel in automobile construction. The matrix is impregnated inhomogeneously with the resin.
Claims15
1-15. (canceled)
A method of producing a motor vehicle component, the method comprising:
- providing a honeycomb core having a plurality of regions, including a lattice structure having corrugated strips with linear strips arranged therebetween, and a plurality of lattice elements which form a nodal point, each lattice element having a matrix and resins of different types and concentrations;
- and
- impregnating resins of different types and concentrations, inhomogeneously two-dimensionally, over each matrix such that zones of the motor vehicle component located in preselected regions of the honeycomb core have different stiffnesses than other regions based upon a probability of impact in an accident by the motor vehicle.
The method of claim 28, wherein impregnating resins comprises spraying the matrix with the resins.
A method of producing a motor vehicle component, the method comprising:
- providing a honeycomb core having a plurality of regions, including a lattice structure having corrugated strips with linear strips arranged therebetween, and a plurality of lattice elements which form a nodal point, each lattice element having a matrix;
- impregnating resins of different types and concentrations, inhomogeneously and two-dimensionally, over each matrix such that zones of the motor vehicle component located in preselected regions of the honeycomb core have different stiffnesses than other regions based upon a probability of impact in an accident by the motor vehicle.
A method of producing a motor vehicle component, the method comprising:
- connecting cover layers, including an outer layer and an inner layer, to a honeycomb core having a plurality of regions arranged between the cover layers, the honeycomb core including a lattice structure having corrugated strips with linear strips arranged therebetween, and a plurality of lattice elements which form a nodal point, each lattice elements having a matrix;
- and
- impregnating resins, inhomogeneously and two-dimensionally, resins of different types and concentrations in each matrix such that zones of the motor vehicle component located in preselected regions of the honeycomb core have different stiffnesses based upon a probability of impact in an accident by the motor vehicle.
