Damage detection of cracks in carbon fibre reinforced composites by pulsed eddy-current testing

Image Characterization of Carbon Fibre Reinforced Composites

A new methodology to detect fibres orientation in composite materials, using image processing tools is introduced. Several examples with manufacturing defects are studied using RIMAPS technique and the Variogram method. The characterization is made from digitized images of the samples. Combined use of RIMAPS and Variogram analyses identified the orientation of fibres and determined the values o...

Characterization of Carbon Fibre Reinforced Composite by Means of Non-Destructive Eddy Current Testing and FEM Modeling

The limitation of non-destructive methods for the inspection of carbon fibre reinforced plastic (CFRP) composites is a major problem for many practical applications of the material, especially in the aircraft industry. This paper presents a study which is directed towards non-destructive characterization of CFRP using eddy current methods. The relationship between the signal from different type...

Eddy Current Pulsed Thermography for Non- Destructive Evaluation of Carbon Fibre Reinforced Plastic for Wind Turbine Blades

Self-healing of damage in fibre-reinforced polymer-matrix composites.

Self-healing resin systems have been discussed for over a decade and four different technologies had been proposed. However, little work on their application as composite matrices has been published although this was one of the stated aims of the earliest work in the field. This paper reports on the optimization of a solid-state self-healing resin system and its subsequent use as a matrix for h...
