Book excerpt: The influence of impact damage on the structural performance of composite laminates was investigated by a joint effort and included nondestructive evaluation (NDE), mechanical testing and analysis. The impacted NASA Industry Standard Compression After Impact test specimen was chosen. Damage characterization incorporated ultrasonic and radiographic methods. Computerized and manual ultrasonic testing from both sides of the test panels provided accurate information on the damaged area. The findings were confirmed by a destructive X-ray microfocus technique combined with an opaque penetrant for damage enhancement. From the NDE data, a simplified damage model was constructed and analyzed for strength and stability. Failure loads and modes were predicted and compared to compression after impact test results. Preliminary tests showed very good agreement.

Download or read book Composite Structures 4 written by I.H. Marshall and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 477 pages. Available in PDF, EPUB and Kindle. Book excerpt: The papers contained herein were presented at the Fourth International Conference on Composite Structures (ICCS/4) held at Paisley College of Technology, Scotland in July 1987. The Conference was organised and sponsored by Paisley College of Technology. It was co-sponsored by the Scottish Development Agency, the National Engineering Laboratory, the US Air Force European Office of Aerospace Research and Development and the US Army Research, Development and Standardisation Group UK. It forms a natural and ongoing progression from the highly successful First, Second and Third International Conferences on Composite Structures (ICCS/l, ICCS/2 and ICCS/3) held at Paisley in 1981, 1983 and 1985 respectively. There is little doubt that composite materials are rightfully claiming a prominent role in structural engineering in the widest sense. Moreover, the range and variety of useful composites has expanded to a level inconceivable a decade ago. However, it is also true that this increasing utilisation has generated an enhanced awareness of the manifold factors which dictate the integrity of composite structures. This is indeed a healthy attitude to a relatively new dimension in structural engineering which will have an increasingly dominant role as the century progresses. Both the diversity of application of composites in structural engineering and the endeavours which will ensure their fitness for purpose are reflected herein.

Download or read book A Field Deployable Nondestructive Impact Damage Assessment Methodology for Composite Structures written by JN. Zalameda and published by . This book was released on 1994 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: A technique is being developed for rapid in-service detection and quantification of damage in composite airframe structures combining thermal and ultrasonic nondestructive evaluation (NDE). Thermal inspection techniques can be used to identify impact damage areas because it is fast, inspects large areas, and is noncontacting. Once an area of concern is identified, characterization of the depth and extent of the damage can be determined using ultrasonic volumetric imaging. Ultrasonic volumetric imaging quantifies the damage by giving a ply-by-ply view of the damage. Single-sided measurements were made on two types of samples, flat panels with through-the-thickness reinforcements and a "Y"-stiffened skin. These samples were impacted with an aluminum ball at various velocities. The thermal results were compared with ultrasonic C-scans and the ultrasonic volumetric results were compared with destructive tests. The thermal images compared well with the C-scan images in both relative size and shape. It was found that the ultrasonic volumetric results gave a better indication of damage than achievable with the destructive specimen evaluation method. It has been shown that a multidisciplinary approach using thermal and ultrasonic NDE techniques is an efficient and informative inspection method for identifying and quantifying damage.
