Abstract
A fiber orientation verification system includes a sensor and an indicator to identify the fiber orientation within each sequentially laid composite material layer. The indicator projects visible indicator lines upon the lay-up surface which are indicative of a desired orientation for the composite material layer. The sensor and the indicator communicate with a computer module which contains a database including a detailed sequence to assure that each layer is proper placed. The operator is thereby provided with an exact location to lay-up each composite material layer and the proper fiber orientation of that layer. Continued verification is thus provided to the operator.
