OBJECTIVES: To evaluate the clinical performance of partial glass-ceramic (IPS e.max Press) posterior restorations. MATERIALS AND METHODS: A total of 765 restorations in 158 patients were placed between 2008 and 2018 and evaluated in a prospective study during regular dental care visits between 2015 …

The goal of this research was to set up suitable laboratory tests and analysis methods for the strength and durability testing of bio-based textile reinforced concrete. This thesis was a preparatory research for the actual development of bio-based TRC applications, which was not undertaken due to unforeseen …

This research proposes new structural lay-outs for large wind turbine blades. The lay-outs were found by an optimisation method where the aerodynamics of wind turbine blades was combined with the structural model of the blade, formulated in a corotational framework. The aeroelastic blade loads were calculated …

Processes have been developed to integrate CIGS solar foils directly in plastic or composite based products. Using injection moulding and vacuum forming it turned out that mechanical stress is applied to the solar foil upon cooling. Using intermediate stress relief layers such as polyolefin this could …

Laminated composites have important applications in modern aeronautical structures due to their extraordinary mechanical and environmental behaviour. Nevertheless, aircraft composite structures are highly vulnerable to impact damage, either by low-velocity sources during maintenance or high-velocity …

PURPOSE: Limited information is available on the effect of Immediate Dentin Sealing (IDS) on the fracture strength of indirect partial posterior restorations. This study evaluated the effect of IDS on the fracture strength and failure types of two indirect restorative materials. MATERIALS AND METHODS: …

Nowadays, composites are mainly produced via petroleum derived chemicals. In a world where petroleum resources are running out, it is essential to find viable options for the replacement of these reserves. Biocomposites are already exploited but they appear to have low resistance to weathering. This …

The current research and design thesis deals with implementation of a 30-meter-long bridge with a cross section made with an innovative hybrid material composed of GFRP composite and steel members. A preliminary design consisting of analytical calculations creates a reference line on top of which FEM …

In the high-tech mechatronics world, aluminum and steel are well known materials, while carbon fiber is often neglected. In the RAAK project 'Composites in Mechatronics', the use of carbon fiber composites in mechatronics is investigated.
