Facilities

ctw/pt

The lab facilities of the Chair of Production Technology cover a wide range of equipments, meant to support the modelling efforts within our research.

Experimental work is necessary to highlight the behaviour of materials and structures before modelling. Also material properties are important. Beside, validation is necessary to explore the limits of the model proposed.Our lab also works within the framework of the faculty Mechanical Testing Laboratory, which regroups the complementary facilities of seven chairs.

Analyses

The series of analysis equipment is meant at providing tools to characterise and measure physical properties and behaviour of materials. They also support various activities as modeling, process experiments, mechanical testing.They include micrography facilities (stereo microscopes, light microscopes, electron microscope), thermo-mechanical analysis and stress measurements. The analysis lab is also supported by a fully equipped preparation lab.Here follows a description of the main analysis equipment.

Jeol NeoScope JCM-5000 Benchtop Scanning Electron Microscope

The Jeol Neoscope JCM-5000 is the 'easy to use' benchtop SEM.

Jeol JSM 6400 Scanning Electron Microscope

The Jeol JSM-6400 is a SEM configured with a Noran energy dispersive X-ray analyzer (EDS system). SEM is a method for high-resolution imaging of surfaces. An incident electron beam is scanned across the sample’s surface, and the resulting electrons emitted from the sample are attracted and collected by a detector and translated into a signal. More

 Atomic Force Microscope (AFM) NanoSurf easyScan 2

The Nanosurf easyScan 2 AFM system is an atomic force microscope that can measure the topography and several other properties of a sample with nanometer resolution. The main parts of the basic system are the easyScan 2 AFM Scan Head, the AFM sample stage, the controller with AFM basic module and the easyScan 2 software.

Stereo Microscope Leica MZ 125

The stereo microscope uses two separate optical paths with two objectives and two eyepieces to provide slightly different viewing angles to the left and right eyes. In this way it produces a three-dimensional visualization of the sample being examined. A stereo microscope has a useful magnification up to 100×. More

Optical microscope Leica DMRX

The Leica DMRX is an upright microscope for material analysis equipped with a wide range of objective lenses. It can be used for bright field, dark field, DIC and fluorescence. Two filter blocks are available for fluorescence. A digital color camera (c-mount) is attached to the system. More

Laser scanning microscope VK 9700 Keyence

Confocal laser scanning microscopy is a powerful tool for high resolution imaging. In conventional light microscopy, both focused and out-of focus light contributes to the image. In confocal microscopy, all structures outside the focal plane of the microscope objective are suppressed. As a result, images of that single focal plane are sharp and less blurred that in wide-field microscopy. More 

Philips X'Pert 1 X-ray Diffractometer

The Philips X’Pert 1 X-ray diffractometer is a versatile device to characterise crystalline materials. It is capable of performing various types of measurements and analyses. The diffractometer has a stationary, centrally placed, X-ray tube with (para focusing) line focus and (parallel beam) point focus employing two goniometers for each type of focus. More 

Mettler Differential Scanning Calorimeter (DSC822E)

The Mettler Toledo Differential Scanning Calorimeter (DSC) measures the difference between the heat flows from the sample and reference sides of a sensor as a function of temperature or time. Differences in heat flow arise when a sample absorbs or releases heat due to thermal effects such as melting, crystallization, chemical reactions, polymorphic transitions… More

 Mettler Analytical Balance & Density Measurement (AT261)

The Mettler Toledo Analytical balance AT261 measures mass with a 0.05mg repeatability. It also features an density determination kit, both for solids and liquids. More 

Mechanical Testing

The production technology lab offers a wide range of Universal Testing Systems to cover a wide range of type and level of loading. These machines are not only used to perform standard tests, but also to characterise the physical behaviour of the materials and structures used in our research. 

Instron 8250 Fatigue system

The Instron 8516 testing machine is a servo-hydraulic controlled fatigue system. Similarly to a universal testing machine, a broad range of mechanical testing is possible. More

 

Zwick 1445 Universal Testing Machine (3x)

The Zwick 1445 Universal Testing System is the lab’s ‘one fits all’. A broad range of mechanical testing can be performed on this machine, as long as it concerns quasi-static tests. More 

Impact Testing

This particular type of loading is well represented within our lab. The facilities make it possible to load different types of structures, from coupon type to small structures, at different rates. 

Dynatup 8250 Falling Weight Impact Machine

The Dynatup 8250 Instrumented Falling Weight Impact Machine (IFWIM) is a component impact tester. (see also Instron-Dynatup). This machine is versatile, as far as the capacity is concerned (low to high impact energy), as well as the specimen geometry. Beam like specimens can be tested, as well as plates and more complex geometries. More

Dynatup 8200 Falling Weight Impact Machine

The Dynatup 8200 Instrumented Falling Weight Impact Machine (IFWIM) is a component impact tester. (see also Instron-Dynatup). This machine is versatile, as far as the capacity is concerned (low to high impact energy) , as well as the specimen geometry. Beam like specimens can be tested, as well as plates and more complex geometries. More

Gas Gun ‘Zebigboom’

This air gun will accelerate a cylindrical projectile to velocities up to 200m/s. It can potentially be used to impact any type of structures. It is now fitted to impact composite plates. More

Production Lab

The production lab of Production Technology is equipped to produce composite specimens using the press technology and the resin infusion technique. The first is mostly dedicated to the production of thermoplastic matrix composite laminates. The second, resin infusion, is a flexible technique for producing thermosetting matrix composite plates and components. Beside, production related measurement equipment is also developed. 

Fontijne TP1000 Hot Press

The Fontijne TP1000 hot press is used to produce flat laminates from prepreg or filmstacking. Closed moulds are mostly used for this purpose. Thermoplastic as well as thersetting prepreg can be used. But also film stacking based laminates or metal laminates can be produced in this press.

Vacuum assisted Resin Transfer Moulding

Infusion of an Non-Crimp Fabric between 2 glass plates for permeability measurement

Vacuum assisted Resin Transfer Moulding does not concern a specific piece of apparatus, but designate a technique requiring a limited amount of equipment to drive resin into a fabric. Basically, only a simple mould part, a vacuum pomp and a closing film are necessary.

Permeameter Κz

Not exactly a production related piece of equipment, rather a home designed apparatus to measure the through-thickness permeability of fabric. This permeability (Κz) is, together with the in-plane permeability (see Vacuum assisted Resin Transfer Moulding), essential to predict the filling of a complex Liquid Composite Moulding product.
