1. 1. Micromechanical Characterization of Thin Paper Materials

   University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen; Lunds universitet/Lunds Tekniska Högskola

   Author : Linus Bengtsson; [2023]
   Keywords : Micromechanical characterization; SEM; In situ tensile testing; Paper deformation; Fiber orientation; Paper mechanics; Technology and Engineering;

   Abstract : Hur ser framtidens hållbara förpackning ut och vad är den tillverkad av? För att besvara denna fråga blir mikromekanisk karakterisering av material en viktig parameter att utforska och förstå. I synnerhet är mikromekaniken hos tunna pappersmaterial intressant då materialet har användningspotential i flera förpackningsapplikationer. READ MORE

3. 2. Reprocessing and Characterization of Polybenzimidazole for High-Temperature Polymer Electrolyte Membrane Fuel Cells

   University essay from Lunds universitet/Centrum för analys och syntes

   Author : Douglas Björkengren; [2023]
   Keywords : polymer electrolyte membrane fuel cells; PEMFC; HTPEMFC; polymer technology; polymer characterization; reprocessing; recycling; polybenzimidazole; PBI; Technology and Engineering;

   Abstract : A reprocessing method of poly(2,2’-(m-phenylene)-5,5’-bibenzimidazole) (PBI) membranes recovered from the production line of High-Temperature Polymer Electrolyte Membrane Fuel Cells (HT-PEMFC) at Blue World Technologies (BWT) has been developed in order to reduce material loss in the production. Redissolution of scrap PBI membranes in poly(phosphoric acid) (PPA) and phosphoric acid (PA) was successful and the subsequent washing procedure produced PBI that could be redissolved in N,N-dimethyl acetamide (DMAc) and suitable for solution casting of new membranes.

4. 3. Structural modifications of polyester fibres induced by thermal and chemical treatments to obtain high-performance fibres

   University essay from KTH/Fiber- och polymerteknologi

   Author : Kartikeya Sharma; [2021]
   Keywords : PET fibres; P3HB fibres; Radial gradient; Chemical modification; Thermal annealing; High-performance fibres; PET-fibrer; P3HB-fibrer; Radiell lutning; Kemisk modifiering; termisk glödgning; högpresterande fibrer;

   Abstract : Del A: Polyetylentereftalat fibrer I detta arbete presenteras olika metoder för att framställa monofilament av polyetylentereftalat (PET) (diameter: 30-50 µm) med en radiell gradient. Nyutvecklad Raman-spektroskopiteknik har använts för att kartlägga dessa inducerade radiella gradienter i t.ex. kristallinitet. READ MORE

5. 4. Fatigue Testing of a Unidirectional Carbon Fiber Reinforced Polymer : Investigation of damage development using Digital Image Correlation

   University essay from KTH/Lättkonstruktioner

   Author : Lars Johan Wenner Berg; [2020]
   Keywords : ;

   Abstract : Carbon Fibre Reinforced Plastic (CFRP) is a material with high specific propertiesand good fatigue and vibration dampening characteristics, and can potentiallybe used instead of steel and aluminium in heavy duty vehicles. This work focuseson testing methodology and the fatigue properties of a unidirectional (UD)material in the 0° and 90°orientation, reproducing and validating the method developedby Wanner[1].

6. 5. Microstructural, Mechanical and Tribological Studies of Ti-6Al-4V Thin Plates Produced by EBM Process

   University essay from Högskolan Dalarna/Materialteknik

   Author : Onimisi Calistus Sanni; [2019]
   Keywords : Additive manufacturing AM ; Electron beam melting EBM ; Mechanical properties; Tribological behaviour; Microhardness; Micro tensile; Thin sections; Ti-6Al-4V;

   Abstract : The titanium alloy, Ti-6Al-4V, is vastly studied and used in many applications because it has a transformation microstructure, which can be tailored for apt properties that are consistent up to 500°C. Compared to conventional steels, this alloy favours certain applications due to its high specific strength, hardenability, corrosion resistance, biocompatibility and weldability. READ MORE
