11. Non-linear behavior of bio-based composite : characterization and modeling
Sammanfattning : The development and application of bio-based composite materials have been frequently studied. Most of the work is done on quasi-static performance of these materials. However, these composites are highly non-linear therefore there is need for investigation of their viscelastic and viscoplastic behavior. LÄS MER
12. Process Modeling of Composite Manufacturing
Sammanfattning : The focus of this research thesis is toward developing a framework for holistic modeling of composites manufacturing of fiber reinforced structural composites. The processes that have been considered are Liquid Composite Molding (LCM) and Out Of Autoclave (OOA) processes, ranging from Liquid Resin Infusion (LRI) and Resin Transfer Molding (RTM) in LCM processes, to Vacuum Bag Only (VBO) and Evac prepregs in OOA processes.

13. Numerical and Experimental Studies of Deployment Dynamics of Space Webs and CubeSat Booms
Sammanfattning : In this thesis, experiments and simulations are performed to study the deployment dynamics of space webs and space booms, focusing on the deployment and stabilization phases of the space web and the behavior of the bi-stable tape spring booms after long-term stowage.The space web, Suaineadh, was launched onboard the sounding rocket REXUS-12 from the Swedish launch base Esrange in Kiruna on 19 March 2012.

14. Flexural Strengthening of Reinforced Concrete Beams Using Externally Bonded CFRP--An Innovative Method for the Application of Prestressed CFRP Laminates
Sammanfattning : A large number of existing bridges in European countries are structurally deficient and functionally obsolete due to the deterioration of aging bridges and the lack of structural and geometric capacity to accommodate the increasing traffic volume and load levels. To meet the demand for holistic and effective strengthening techniques the SUREBRIDGE solution is proposed for the refurbishment of concrete bridges, which includes the technique of using prestressed carbon fiber reinforced polymer (CFRP) laminate as externally bonded reinforcement for flexural strengthening.

15. Recyclable self-reinforced ductile fiber composite materials for structural applications
Sammanfattning : Lightweight structures in vehicles are a proven way to reduce fuel consumption and the environmental impact during the use. Lower structural weight can be achieved by using high performance materials such as composites or using the material efficiently as a sandwich structure. LÄS MER
