ArthroKnee: Interactive gonarthrosis data base for the three-dimensional microstructure, geometry, and biomechanics of the knee joint

Funding period: 1.10.15 - 30.09.17

Due to the increasing life expectancy the incidence of osteoarthritis (OA), the degeneration of articular cartilage and bone in the knee joint, is increasing worldwide. If all alternative treatment options are unsuccessful knee replacement surgery is inevitable. Concerning the annual number of knee replacement surgeries, Austria occupies an international leading position. Although the success rate of knee arthroplasties is high, complications like the loosening of the implant necessitate subsequent treatments. Moreover, the morphology and microstructure of the knee joint varies considerably between patients, therefore the anatomical expertise of orthopedic surgeons is essential. However, the clinical diagnosis is mainly based on radiological findings that neglect the three-dimensional architecture and microstructure of the knee joint.

Project for Non-destructive Testing and Tomography Plus

K-Project ZPT+: September 2014 - August 2018

The new K-Project for non-destructive testing and tomography plus (ZPT+) is a further development of the preceding very successful K-Project ZPT building on the established knowledge base. ZPT+ is the next logical step forward focusing on the cutting edge applications, new industrial demands and scientific expertise.

spaceXCT: X-ray Techniques for NDT and Damage Characterization of Space Materials and Components

Funding period: 1.06.16 - 30.05.17

One of the main challenges to accelerate the acceptance and use of advanced materials (e.g. polymer matrix composites, additively manufactured parts & electrical, electronic and electro-mechanical components) in the European Space Agency (ESA) is to establish a broadly accepted materials and process quality system, including adequate non-destructive testing (NDT) procedures. However, to profoundly exploit the advantages of advanced manufacturing for space applications, and to ensure highly reliable parts, new approaches to both manufacturing and non-destructive testing (NDT) are needed. NDT procedures must be able to track unique features such as small scale and deeply enclosed porosity, complex part geometry, and subtle internal features.

In the course of spaceXCT we exploit innovations of advanced X-ray imaging technologies, e.g. high resolution X-ray computed tomography (XCT) and grating interferometer X-ray computed tomography (TLGI-XCT), addressing various problems concerning materials science and material processing in space applications. We introduce advanced X-ray technology overcoming disadvantages of standard methods ranging from the inspection of thermally induced crack propagation in polymer composites, void growth during load testing of additively manufactured titanium parts, and crack growth in solder joints of ball grid arrays on multilayer printed circuit boards.

International Network for the Training of Early stage Researchers on Advanced Quality control by Computed Tomography

InterAQCT: October 2013 – September 2017

The non-destructive quality control of a wide variety of high-added value products, produced by innovative manufacturing techniques, remains a challenge. Examples include additive manufacturing parts, micro parts, and fibre reinforced composite parts. Common to these workpieces is the dependency of their performance on internal and inaccessible elements. Nevertheless, customers in multiple sectors are requesting certified quality and reliability.

Quantitative inspection of complex composite aeronautic parts using advanced X-ray techniques

QUICOM: October 2012 – September 2015

Recent years have seen a rapidly growing demand from aeronautic industry regarding function-oriented, highly integrated, energy-efficient and lightweight structures. In advanced composites a promising material was found, which integrates these characteristics allowing for continuously elevating the complexity of new components concerning shape and internal structure. The consequences of this increasing complexity are tremendously raising efforts in quality control, as conventional nondestructive testing methods are reaching their limits and become either extremely time-consuming or unusable for a full inspection. QUICOM aims at taking the next big step in the development of aeronautic components by...

Compact X-ray computed tomography system for non destructive characterization of nano materials

NanoXCT: May 2012 – April 2015

Within the past decades, advances in miniaturization from micro to nano-scale have had dramatic impacts on our lives. Consumer electronics, which once occupied large volumes, now fit in the palm of a hand. But nanotechnology does not only improve electronics. Also material sciences, chemical engineering or biology are strongly profiting from nanotechnology. The tremendous achievements in all of these areas would not have been possible without corresponding material analytics techniques. Material analytics for nano-scale characterization currently cover destructive methods, surface inspection methods or 2D methods. To date it is not possible to get a comprehensive representation of a specimen including internal and external 3D-structure analysis as well as a chemical analysis without destroying the sample. In this respect nano-scale material analytics is currently on the edge of a new era, which is targeted in NanoXCT. The project addresses the limitations of conventional techniques using 3D X-ray computed tomography, which allows for a non-destructive and fully three-dimensional characterization of specimens.

K-Project for Non-destructive Testing and Tomography

K-Project ZPT: September 2009 - August 2014 

The need for NDT methods is driven by the development/innovation of new products, materials and technologies and by the demand for enhanced quality control and cost reduction in industry. Many countries have already established specialized research centre for NDT. With the K-Project an applications-orientated NDT research centre will be created in Austria concentrating and strengthening research on modern NDT methods and application in the country. The combined expertise on NDT-methods and applications-oriented materials science will build a unique knowledge base with regard to non-destructive evaluation. The main focus will be on the following methods...

3D Simulation of defect accumulation in orientation-dependent fiber-reinforced polymers through computed tomography

3D-SFC: March 2012 – February 2014

The major goal of this project is to realise reliable strength and lifetime predictions for real fibre reinforced thermoplastic polymers that consider the effect of changes in microstructure at fatigue testing on the mechanical stability of the final product. Especially for highly loaded components from automotive industry, fatigue tests are performed in order to determine damage by use of three-dimensional computed tomography. Using this information, theoretical models will be established that consider the mechanisms of damage and local fibre orientation, which are able to predict the remaining lifetime of a product. Product design can be performed considerably more time- and material- efficient by use of the developed models. The results of this project are especially important for automotive industry, light weight applications as well as leisure-, electrical- and consumer goods industry.

Development of a repair-methodology for carbon fiber reinforced components

EraSME ReCarboFit: April 2012 – March 2014

With its high rigidity, stability, fatigue strength and low weight, carbon fiber reinforced plastics, short CFRP, own outstanding mechanical characteristics. Thereby these materials have become interesting for a broad range of application areas. CFRP is increasingly used in aviation-, automotive- and in high performance sports-industry for quite a few years now. Today the remaining disadvantage of the material is by far the restricted suitability for repair in case of damage.
