PREPARATION OF A COMPOSITE MATERIAL PRODUCT CONTAINING DIFFERENT FUNCTIONALITY ZONES

摘要

The object of the invention is a process for manufacturing a product in composite materials comprising areas with different functionalities from a knitted preform. The inventors have discovered that it is possible to knit a dry preform comprising areas of different composition and then to transform it by fusion into a solid composite material comprising areas with different functionalities. By different functionality, it is possible to provide areas of different rigidity, areas of different abrasion resistance, areas of different electrical or thermal conductivity, areas of different transparency.
