Electrical Resistance Change of Unidirectional CFRP Due to Applied Load

Final report Project Title: Wireless Damage Monitoring of Laminated CFRP composites using Electrical Resistance Change

It is difficult to detect delamination of rotating composite components like helicopter and wind turbine blades while in-service with a wired system. In the present study, a wireless system using a tiny oscillation circuit for detecting delamination of carbon/epoxy composites is proposed. In this system, a tiny oscillation circuit is attached to the composite component. When delamination of the...

Processing and electrical characterization of a unidirectional CFRP composite filled with double walled carbon nanotubes

The Influence of Graphene Oxide on the electrical conduction in unidirectional CFRP laminates for wind turbine blade applications

The incorporation of composite CFRP in wind turbine blades to allow for longer and lighter blades challenges the efficiency of their lightning protection system. The electrical anisotropy of CFRP materials is a key factor and affects their performance. The present study investigates the influence of adding Graphene Oxide (GO) nanoparticles to CFRP as a mean to improve their electrical conductiv...

Evolution of the Electrical Resistance of Woven Cfrp Laminas during Mechanical Tests

Reliable failure prediction methods are required for extending the range of applications of carbon-fiber-reinforced-polymers. In parallel, the development of non-destructive tests (NDT) for continuous health monitoring would result in structures of improved durability and safety. Carbon fibre-reinforced polymers (CFRP) have been investigated for the development of “smart” structures characteriz...

Contract number : FA 2386 - 09 - 1 - 4038 Research title : Damage detection of laminated CFRP structures using electric pulse wave transmission

Carbon Fiber Reinforced Polymer (CFRP) laminates are applied to many aerospace structures. For these laminated CFRP structures, it is quite difficult to detect internal damage such as delamination, matrix cracks, and local fiber breakages. Carbon fibers are adopted as reinforcement in CFRP and it is an excellent electric conductor at the same time. The carbon fiber has been used as a strain sen...
