Residual Strength of Composite Hulls after Impact
Duus, Pål (Master thesis, 2016)Norsafe MILPRO boats operates in different waters at high speeds. The chance of hitting unknown objects e.g. floating logs is present. Being able to judge the damages and the residual strengths to these impacts are desirable. ... -
Residual Strength of Composite Pressure Vessels After Impact
Landvik, Sondre (Master thesis, 2016)Composite overwrapped pressure vessels are increasingly being applied for transportation and storage of pressurized fluids. With superior material properties, fiber-reinforced composites are central to increasing operating ... -
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 ...
