Resin Dosing for Closed Impregnation Filament Winding: Process Optimization
Pathak, Raoul (Master thesis, 2019)Denne rapporten dekker en undersøkelse rundt bruken av datastyrt tilføring av epoksyresin, eller "resindosering", under filamentvikling, for å optimalisere short-beam styrke i karbonfiberkompositter. Det gjøres bruk av en ... -
Sealing materials seals for arctic applications
Eichstaedt, Joanna Anna (Master thesis, 2016)This thesis is about exploring the performance of rubber O-ring seals made of materials such as: ELAST-O-LION 101, base HNBR and HNBR 50 CB, under cold temperatures and compressions equal to 10% and 20%. Initially a test ... -
Sensing of Structural Damage with OBR Based Fibre-Optic Networks
Lasn, Kaspar; Sæter, Erik; Echtermeyer, Andreas (Chapter, 2018)Optical fibre networks based on optical backscatter reflectometry i.e. the OBR technology is a new and promising method for the inspection of safety critical structures. It utilizes regular telecommunications grade optical ... -
Tailoring Biocomposites with Reduced Water Uptake for 3D Printing
Holmen, Solveig (Master thesis, 2017)In this study, two different grades of bioPE, with a varying melt flow index (MFI) were tested for making biocomposites reinforced with wood fibre. A low MFI was found to be more adequate for the manufacturing. Filaments ... -
Time-Temperature-Plasticization Superposition Principle: Predicting Creep of a Plasticized Epoxy
Krauklis, Andrey; Akulichev, Anton; Gagani, Abedin; Echtermeyer, Andreas (Journal article; Peer reviewed, 2019)Long-term creep properties and the effect of water are important for fiber reinforced polymer (FRP) composite materials used in offshore applications. Epoxies are often used as a matrix material in such composites. A typical ... -
Using Tolerance Bounds for Estimation of Characteristic Fatigue Curves for Composites with Confidence
Ronold, Knut O.; Echtermeyer, Andreas (Journal article; Peer reviewed, 2021) -
Utmatting av komposittrør med boltforbindelser
Horn, Marcus Vincent (Master thesis, 2016)Ett system for å koble komposittrør opp mot metallstrukturer har blitt utviklet ved NTNU. Løsningen består av ett metallendestykke med bolter skrudd inn radielt. Egenskapene til et komposittrør koblet opp til to metallendestykker ... -
Utmattingslevetiden av limfuger
Sæter, Erik (Master thesis, 2016)Denne masteroppgaven har undersøkt effekten av utmatting på «single lap»-forbindelser gjennom eksperimentelt arbeid og tøyningsfeltanalyse. Hovedfokus har vært på 100 mm «single lap»-forbindelser bestående av stål og ... -
Zero Stress Aging of Glass and Carbon Fibers in Water and Oil—Strength Reduction Explained by Dissolution Kinetics
Echtermeyer, Andreas; Krauklis, Andrey; Gagani, Abedin; Sæter, Erik (Journal article; Peer reviewed, 2019)Understanding the strength degradation of glass and carbon fibers due to exposure to liquids over time is important for structural applications. A model has been developed for glass fibers that links the strength reduction ...
