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

摘要

According to the invention, the fibre direction of a carbon-fibre material of an object which is to be tested is detected using the polarisation direction of light reflected by the object which is to be tested. If unpolarised light, for example, is incident on carbon-fibre, the light reflected by the fibres is polarised in the fibre direction.
