Low mass double-layer carbon layers and improved mechanical electrical properties

摘要

Carbon layers (100), withA first carbon fibre layer (102) of unidirectional parallel carbon threads (108) arranged in a first angle range comprising an angle of approximately +30 to +60 to a longitudinal direction of the carbon layer; andA second carbon fibre layer (104) of unidirectional parallel carbon threads (112) arranged in a second angle range comprising an angle from approximately -30 to approximately -60 to the longitudinal direction of the carbon layer, the second carbon fibre layer being positioned on the first carbon fibre layer,The first carbon fibre layer and the second carbon fibre layer are sewn together by means of a thermally activated polyester thread (106) with at least one seam.
