Get this from a library. Ultrasonic inspection of carbon fiber reinforced plastic by means of sample recognition methods. [R Bilgram; United States. National Aeronautics and Space Administration.]. Ultrasonic inspection is one of the most promising nondestructive testing methods applied during manufacturing, pre-service and in-service inspection of components like pipes, vessels or steel plates.

Carbon Fiber Reinforced Plastic (CFRP) is an important material to make aircraft structure components. However, damage detection is very crucial to aircraft safety and the type of a detected. The form of the structure determines the types of features of concern and the NDT techniques that may be applied to detect and measure them.

Table summarizes some general thoughts and considerations on the NDT of polymer composite structure. ASTM also provides guidance on NDT for polymer ound is the predominate method for composite laminate inspection, Author: R.H.

Bossi, G.E. Georgeson. A portable automated scanner for non-destructive testing of carbon-fibre-reinforced polymer (CFRP) composites has been developed. Measurement head has been equipped with an array of newly developed radio-frequency (RF) inductive sensors mounted on a flexible arm, which allows the measurement of curved CFRP samples.

The scanner is also equipped with vacuum sucks providing Cited by: 3. Journal of Biomimetics, Biomaterials and Biomedical Engineering Materials Science. Defect and Diffusion Forum. Investigation of tendon ducts by means of ultrasonic echo methods: A comparative study M.

KEYWORDS: Fiber reinforced polymers, Infrared radiation Read Abstract + Non-destructive Evaluation (NDE) is a field that is used to identify all kinds of structural damage in an object of interest without resulting in any permanent damage or modification to the object.

In this article, the state-of-the-art multi-wave and hybrid imaging techniques in the field of nondestructive evaluation and structural health monitoring were comprehensively reviewed. A new direction for assessment and health monitoring of various structures by capitalizing the advantages of those imaging methods was discussed.

Although sharing similar system configurations, the imaging Cited by:   Nonlinear ultrasonic methods for nondestructive damage assessment in structural materials (Conference Presentation) Determination of depth and size of defects in carbon-fiber-reinforced plastic with different methods of pulse thermography.

The primary load-bearing component in a composite material is the reinforcing fibres. This paper reports on a technique to study the fracture of individual reinforcing fibres or filaments in real-time. Custom-made small-diameter optical fibres with a diameter of 12 (±2) micrometres were used to detect the fracture of individual filaments during tensile loading of unreinforced bundles and Cited by: 7.

For example, carbon fiber reinforced polymers (CFRPs) show a low weight, but high specific stiffness and high specific strength.

CFRPs are also cost effective for the properties they deliver, as stated Bhattacharya et al. CFRP is thus a promising candidate material for a large variety of new automotive, aeronautic and space components Cited by: 8.
