METHOD OF MANUFACTURING COMPOSITE MATERIALS WITH MONITORING CAPACITY AND MATERIAL OBTAINABLE
ES2567527
Method of manufacturing composite materials with monitoring capacity and material obtainable. A method of obtaining a composite material, ie a method of manufacturing a composite material, as well as the composite material obtainable by said obtaining method is detailed in this document. The composite material has data capture means, sensor, which is embedded in the material itself and which have external contacts so that they can be connected to any type of instrumentation that allows carrying out tests or tests of various kinds in the manufactured material, during its manufacture or when the material is in working order.

Multifunctional sensor for low-cost fabrication of composite components by vacuum infusion process. How it works: The thin sensor is laid between dry fabric layers and connected to a simple electrical power meter. During resin infusion and curing, the sensors provides real-time information about the resin flow and the gel point. After curing the sensor remains embedded in the composite and can be used for structural health monitoring (SHM) and damage detection. - Non-invasive. The sensor is thinner than a human hair. - Robust. The sensor is tougher than steel. - Simple. Operates with electrical stimuli
