Abstract
In this tape (15), the fibers are discontinuous and have a length distribution such that the mean fiber length, that is to say the mean length of 50% of the fibers in a specimen, is between approximately 40 and 70% of the length of the longest fiber in the specimen, the fibers being combined by means of a resin (10) or of an adhesive having a fugitive nature. Application to the production of components made of composites.
Claims16
A unidirectional tape of carbon fibers, wherein the fibers are discontinuous, have a length distribution such that the mean fiber length is between approximately 40 and 70% of the length of the longest fiber, as determined by comparing the mean length of 50% of the fibers in a specimen with the length of the longest fiber in the specimen, and the fibers are combined with a resin or with an adhesive having a fugitive nature.
A unidirectional tape of carbon fibers, wherein the fibers are discontinuous, substantially parallel and have a length distribution such that the mean fiber length is between approximately 40 and 70% of the length of the longest fiber, as determined by comparing the mean length of 50% of the fibers in a specimen with the length of the longest fiber in the specimen, and the fibers are combined with a resin or with an adhesive having a fugitive nature.
