Abstract
Official abstract text for this publication.
A honeycomb structure comprising carbon-fiber non-woven, sandwich structure comprising the honeycomb structure, and process for the production of the honeycomb structure.
First claim
Opening claim text (preview).
The invention claimed is: 1. A honeycomb structure comprising carbon-fiber non-woven and unidirectional fibers wherein a ratio by mass of carbon-fiber non-woven to unidirectional fibers is greater than 10:1. 2. The honeycomb structure according to claim 1 , wherein the honeycomb structure is composed predominantly of carbon-fiber non-woven. 3. The honeycomb structure according to claim 1 , wherein the carbon-fiber non-woven comprises reclaimed carbon fibers. 4. The honeycomb structure according to claim 1 , wherein a length of the fibers of the carbon-fiber non-woven is from 6 to 50 mm. 5. The honeycomb structure according to claim 1 , wherein the fibers of the carbon-fiber non-woven are predominantly unoriented. 6. The honeycomb structure according to claim 5 , wherein the fibers of the carbon-fiber non-woven have a random orientation. 7. The honeycomb structure according to claim 1 , wherein the honeycomb structure is impregnated with synthetic resin. 8. The honeycomb structure according to claim 1 , wherein the honeycomb structure additionally comprises fire-retardant additives. 9. A sandwich structure comprising a honeycomb structure comprising carbon-fiber non-woven and unidirectional fibers wherein a ratio by mass of carbon-fiber non-woven to unidirectional fibers is greater than 10:1. 10. The sandwich structure according to claim 9 moreover comprising two substantially parallel-arranged outer layers, between which the honeycomb structure is arranged, wherein the walls of the honeycomb structure are arranged so as to be substantially orthogonal to the outer layers. 11. The sandwich structure according to claim 9 , wherein the outer layers are composed of at least one of GRP, CFRP and metal.
