21. Barrier Plastics, Processing of Wheat Gluten and A New Method to Measure Permeability
Sammanfattning : One way to extend the shelf life for foodstuff is to usemodified atmosphere packaging (MAP). It is important that MAPare gas tight or in some rare cases permselective to preservethe right gas mix. LÄS MER
22. Plate bonding : strengthening of existing concrete structures with epoxy bonded plates of steel or fibre reinforced plastics
Sammanfattning : This thesis deals with several aspects of the plate bonding problem, i.e. when steel or fibre reinforced plastics (FRP) plates are bonded to a concrete structure with the use of an epoxy adhesive. Both theoretical work and laboratory tests are presented as well as a full scale test on a strengthened concrete bridge. LÄS MER
23. Bio-based materials from crambe and carinata industrial oilseed meals : compression moulded and extruded oilseed meal plastics
Sammanfattning : Protein-based plastics are considered as a new route for valorisation of oilseed meal from the industrial oil crops Crambe abyssinia (crambe) and Brassica carinata (carinata) as they cannot be used for animal feed or human food. To convert oilseed meals into protein-based plastic films compression moulding was used with varying processing temperature, chemical additives and protein extraction conditions. LÄS MER
24. On the multifunctional performance of structural batteries
Sammanfattning : The structural battery composite is a composite material that can store electrical energy (i.e. work as a battery) while simultaneously provide mechanical integrity in a structural system. Due to its inherent ability to store energy this material offers significant weight savings on a system level. LÄS MER
25. Transport Properties and Durability of LCP and FRP materials for process equipment
Sammanfattning : This thesis focuses on transport properties and durability of liquid crystalline polymers (LCP)and fibre reinforced plastics (FRP) with regard to application in industrial process equipment.In the first part of the study the possibility of using a thermotropic LCP of type Vectra A950as lining material for FRP process equipment was investigated.
