Technical Details & Test Data
- Thermhex Organosandwich – The New Sandwich Material
The Organosandwich production is based on the patented ThermHex process. The process enables the continuous inline production of thermoplastic honeycomb cores in a fully automatic production line.
By using our lightweight Organosandwich weight savings of over 80 % are possible compared to a monolithic construction. In comparison to a monolithic organosheet laminate, a sandwich of the same stiff ness requires less number of layers, which means considerable cost savings when using the Organosandwich.
The Organosandwich consist of 0°/90° cross ply laminate skin layers made of continuous glass fi ber reinforced polypropylene (GF/PP). The folded honeycomb core material consists of a polypropylene as well. This allows an optimal bonding between core and skin layers in the lamination process by thermoplastic welding. The sandwich can be pressed locally to a monolithic laminate which allows the thermoforming of multi-curved shell structures and the pressing of pressure stable monolithic joining surfaces in one step. The pressed areas off er the possibility of functional integration by means of injection molding. Hence, complex lightweight parts can be produced very cost-effi cient in short cycletimes which is essential for many automotive applications.
