Digitization platform for the predictive evaluation of aerospace components by multimodal multiscalar inspection

BeyondInspection: 01.12.2019 - 31.11.2022

For aeronautic applications, aside zero-defect manufacturing, also (almost) lot-size-one production is an important feature of the associated manufacturing, testing and simulation processes. The evaluation of the complex mode of impact of the micro- and mesostructure of manufacturing effects and the interrelationships on the mechanical properties of new highly integrated (sub)components represents a major challenge.Increasing the competitiveness of Austrian production sites is essential and can only be achieved by significantly reducing non-quality costs and production costs with constant or increasing component quality.

Multimodal and in-situ characterization of inhomogenous materials

MiCi: 01.01.2016 - 31.12.2021

Multimodal and non-destructive testing (NDT) methods are essential in order to characterize materials during their processing, e.g. during thermo-mechanical treatments, and to enable in-situ monitoring of the production process. In this project different NDT methods will be realized in a multimodal test rig. This enables the comparability of different NDT methods. In addition, a new high-resolution X-ray computed tomography system with in-situ stages will be acquired and used for the characterization and validation of NDT methods. Beneath experimental validations, resolution limits of the different NDT methods will be compared to theoretical limits. The experimental and theoretical approach will help to identify the best NDT methods for characterizing certain processes and to locate critical defects within the inspected materials.

ADAM - Advanced Multimodal Data Analysis and Visualization of Composites based on Grating Interferometer Micro-CT Data

ADAM project duration: 01.03.2016 - 28.02.2019

Within recent years, the need for new, cost-effective, function-oriented, highly integrated, and light-weight components has strongly grown in many high-tech industries such as aerospace, automotive, marine, and construction. The drivers behind this trend are mainly found in the rising application demands regarding efficiency, safety, environment, and comfort. Among desired functional and -mechanical properties, the requirements on new materials and components include high strength, elasticity, durability, energy efficiency, and light weight. Unlike conventional materials such as aluminum, steel, or alloys, fiber-reinforced polymers (FRPs) – composites made of a polymer matrix reinforced with carbon, glass, or other type of fibers – fulfill these requirements to a high extent. To design new materials and components, detailed investigations and characterizations of FRP materials are vital. In industrial settings, FRP components and materials are nondestructively tested, e.g., by visual inspection, tapping, or ultrasonic inspection. However, conventional methods are increasingly facing their limits regarding accuracy, level-of-detail, and inspection time. To overcome these limitations, industrial 3D X-ray computed tomography (XCT) has received much attention in quality control due to its high spatial resolution and ability to precisely capture external and internal structures in one scan. Compared to other non-destructive testing methods for FRPs, XCT is yet the only method capable of delivering full 3D information for detailed inspection and quality control.

Quantitative X-ray tomography of advanced polymer composites

FWF-FWO: 01.04.2017 - 31.03.2020

Advanced composite materials (ACMs) typically contain two or more constituents, such as matrix, fibers, inclusions and pores, with different physical and chemical characteristics. When combined, they produce a material with unique properties in terms of weight, strength, stiffness, or corrosion resistance.

To inspect and study their 3D internal structure in a non-destructive way, the ACMs are imaged using X-ray computed tomography, in which a 3D dataset is reconstructed from the X-ray radiographs. The 3D dataset is subsequently further processed and analyzed in multiple sequential steps. This conventional workflow, however, suffers from inaccurate modeling and error propagation, which severely limits the accuracy with which ACM parameters of interest can be estimated.

Com3d-XCT: Competence Center for High-Resolution 3D X-ray Imaging

Funding period: 1.10.16 - 30.09.19

interreg Austria Czech Republic EN RGB

Non-destructive testing (NDT) of components by means of microcomputed tomography (XCT) is an important task in many fields, e.g. in the automotive and aerospace sector. However, the demands towards NDT methods are continuously increasing due to the development of advanced, complex material systems. Accordingly, new multi-disciplinary NDT approaches have to be developed to approach the challenges in the in-depth 3D characterization of advanced materials.

MetAMMI: Metrology for Additively Manufactured Medical Implants

Funding period: 1.06.16 - 30.05.19

The medical sector is set to benefit immensely from the rapidly expanding additive manufacturing (or 3D printing) industry, which has the capability to print a range of medical devices, such as prosthetics, dental implants and hearing aids, tailored to a specific patient.

While medical devices are subject to strict safety requirements, additive manufacturing technology has advanced at a much faster pace than the available standards and quality controls. The high roughness, complex geometries, and internal structures of additively manufactured medical devices make acquiring accurate data for quality control challenging.

Photonic Sensing for Smarter Processes

K-Project PSSP: September 2018 - August 2022 

The aim of the K project PSSP is to generate process knowledge with photonic methods which did not exist in this way before. The efficiency of production processes shall be significantly improved with these methods. Through specific research and development photonic methods can be applied before, but also directly in the production line. With the gained knowledge the process parameters, material and resources can be optimized.

Project for Non-destructive Testing and Tomography Plus

K-Project ZPT+: September 2014 - August 2018 

For 4 years 19 partners work on the further development of the central non-destructive testing methods - industrial computed tomography (CT) and laser ultrasound (LUS) - for the inspection and characterisation of compounds and hybrid-components.

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.
