  • METHOD AND ARRANGEMENT FOR PRODUCTION OF AN INTEGRAL HOLLOW-PROFILED COMPONENT WITH FIBRE COMPOSITE MATERIAL
    Publication number: 20110206875
    Abstract: Method for production of an integral hollow-profiled component with fibre composite material comprising at least the following steps: a) providing at least one inner tool core, b) covering the at least one inner tool core with at least one layer of fibre composite material, c) curing the at least one layer of fibre composite material, and d) removing the at least one inner tool core. This makes it possible to produce particularly dimensionally accurate aircraft components, which have an integral hollow-profiled component with a tapering cross section and a plurality of longitudinally running stringers.
