Heating Methods and Detection Limits for Infrared Thermography Inspection of Fiber-Reinforced Polymer Composites

Use of infrared thermography to measure fiber orientation on carbon-fiber reinforced composites

Carbon-fiber reinforced composites are widely used in the industry. One of the key features regarding their quality and usefulness is related to the fiber orientation and contend. One technique that is used to test this kind of material is Infrared Thermography (IT). In this paper it is presented a technique based on diode-laser spot heating to measure fiber orientation on the surface of a carb...

Non-Destructive Testing of Carbon Fiber Reinforced Plastic by Infrared Thermography Methods

Composite materials are one answer to the growing demand for materials with better parameters of construction and exploitation. Composite materials also permit conscious shaping of desirable properties to increase the extent of reach in the case of metals, ceramics or polymers. In recent years, composite materials have been used widely in aerospace, energy, transportation, medicine, etc. Fiber-...

Flash Thermography to Evaluate Porosity in Carbon Fiber Reinforced Polymer (CFRPs)

It is a fact that the presence of porosity in composites has detrimental effects on their mechanical properties. Then, due to the high probability of void formation during manufacturing processes, it is necessary to have the availability of non-destructive evaluation techniques, which may be able to discover the presence and the distribution of porosity in the final parts. In recent years, flas...

Three-dimensional characterization of cortical bone microstructure by microcomputed tomography: validation with ultrasonic and microscopic measurements.

BACKGROUND The porosity of human cortical bone is one of the major parameters conditioning bone strength. The purpose of this study was to validate the characterization of human cortical bone microarchitecture using microcomputed tomography (microCT). To validate this microCT technique, the structural measurements were compared with other methods such as ultrasonic techniques and scanning elect...
