During this session, MWI will present the latest advancements in composite material NDT inspection. Our test methods allow for in-process QC at production speeds greater than 200 linear feet per minute at a two-inch linear resolution resulting in nearly 100% continuous inspection (600 linear feet per minute is achievable). In laboratory QA environments, there has been an impressive reduction in cycle time from hours or minutes down to seconds. Our equipment will effectively reduce material waste while saving you time and money.
MWI Laboratories will present an overview of their latest developments in rapid, non-destructive testing for inspecting composite material using the revolutionary Gaussian Beam technology combined with the most recent developments in High-Performance Vector Network Analyzers (VNA).
The three primary areas to be covered are: first, lessons learned and VNA trade secrets for improving inspection speed while maintaining accuracy, second, high-speed in-process QC inspection techniques, third, QA inspection of composite materials in a laboratory environment and depot repair.
- Compare and contrast different Vector Network Analyzers (VNA) available within the industry and select which VNA with which option that are necessary to meet your production inspection needs
- Learn how to evaluate and maximize the performance of their current Vector Network Analyzers while maintaining the highest level of accuracy and when to purchase a new analyzer
- Determine how turnkey NDT inspection systems can be used to improve your specific manufacturing lines for in-process QC, laboratory QA or depot repair applications
Why Is It Important?
Over the last three decades, test systems designed to monitor quality assurance (QA) or in-process quality control (QC) processes, utilized mass spectrometry or colorimetric methods borrowed from the medical or chemical industries or narrow banded microwave test fixtures. These processes were expensive and often required the destruction of the composite materials, to perform the testing. As military aerospace applications increasingly use composite materials, the need to inspect and control the uniformity of mechanical strength and electromagnetic absorbance mandates better testing methods to decrease upstream costs. Furthermore, as commercial related industries grow their composite material businesses, they too will need to control product quality, while diminishing their manufacturing expenditures. Until two years ago, placing Vector Network Analyzers (VNA) combined with Non-destructive Test (NDT) fixtures on manufacturing lines to control the quality of military aerospace composite materials was very expensive and slow. Yet, they were an advancement over off-line narrow banded destructive test methods to manage the manufacturing process. Although, other standard non-destructive test (NDT) methods such as Eddy current, ultra-sound and X-ray are effective inspection methods for metal applications; they are often slow and difficult to use, dangerous to production staff, or destroy the composite material during testing.
MWI’s systems are presently used for real-time characterization and control of the composite’s material properties (permittivity, permeability, loss tangent, ohms/sq, impedance, etc.) in materials such as honeycomb/foam structures, resistive films, MagRams, resins/powders, circuit board laminates as well as for the detection of defects and FOD. (such as uniformity, resin starvation/excess, and metal, plastic or glass particles) in either the final part or more critical areas of upstream QC of the raw materials used in the manufacturing of these critical composite materials.
