11. High Performance Bio-based Composites : Mechanical and Environmental Durability
Sammanfattning : The presented work is a part of the ongoing effort on the development of high performance bio-based composites with enhanced durability, under static and dynamic mechanical loading including the exposure to elevated humidity. The impact of relative humidity on the performance of cellulosic fibers (natural and regenerated), bio-based resins and their composites was studied. LÄS MER
12. Durability of sprayed concrete : steel fibre corrosion in cracks
Sammanfattning : A combination of sprayed concrete technique and steel fibre technology gives obvious advantages when saving the work needed to place conventional reinforcement. In rock strengthening applications this is most accentuated. Sprayed concrete in general, made by skilled workmen, will generally be of high quality and good durability. LÄS MER
13. Steel fibre corrosion in cracks : durability of sprayed concrete
Sammanfattning : Steel fibre reinforced sprayed concrete is common practice for permanent linings in underground construction. Today there is a demand on "expected technical service life" of 120 years. Thin steel fibres could be expected to discontinue carrying load fast with a decrease of fibre diameter caused by corrosion, especially in cracks. LÄS MER
14. Durability of Embedded Fibre Optic Sensors in Composites
Sammanfattning : This thesis concerns various aspects of the durability offibre optic sensors embedded in composite. Since repair orreplacement of embedded sensors is not generally possible, thefunctional reliability of embedded sensors is one of the mostimportant prerequisites for successful use. LÄS MER
15. Electrochromism in Metal Oxide Thin Films : Towards long-term durability and materials rejuvenation
Sammanfattning : Electrochromic thin films can effectively regulate the visible and infrared light passing through a window, demonstrating great potential to save energy and offer a comfortable indoor environment in buildings. However, long-term durability is a big issue and the physics behind this is far from clear. LÄS MER
