MEASURING A FIBRE DIRECTION OF A CARBON FIBRE MATERIAL AND PRODUCING AN OBJECT IN A CARBON FIBRE COMPOSITE CONSTRUCTION

摘要

ABAccording to the invention the fibre direction of a carbon fibre material of an object (10) which is to be tested is detected using the polarisation direction of light (32) reflected by the object which is to be tested. If unpolarised light (30) for example is incident on carbon fibres (16) the light reflected by the fibres is polarised in the fibre direction (34 34).
