1. Method Development & Analysis of Seals using FEM
Master-uppsats, KTH/MaskinkonstruktionSammanfattning : Hyperelasticity is a significant property of rubber, taken advantage of in engineering applications. A common application is the use of seals to prevent fluid transfer (liquid or gas) between solid regions. Volvo CE is often depending on external supplier when developing seals. LÄS MER
2. Synthesis and characterization of lactic acid-based elastomers
Master-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomiSammanfattning : Synthesized polymer from bio-based and renewable resources reported as an attractive substitution for fossil-fuel based polymers. Therefore, this work has focused on using sustainable material for production of elastomers to reduce the environmental impact of fossil-based elastomers and overcome the shortage of non-renewable fuels.

3. Compression Characteristics of Elastomer Elements
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : Compression of elastomer elements are nonlinear due to the cross-linked molecular structure owing to a property known as hyperelasticity. Hyperelasticity is defined as the nonlinear stress-strain behavior shown by rubber like materials which can be strained up to a range of 700% in tension and up to 40% in compression. LÄS MER
4. Development Model of a Gas Pressure Regulator for Spacecraft Propulsion : Design Enhancement and Testing
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : This thesis treats the testing, analysis, and continued development of a mechanical pressure regulator prototype, intended for use in spacecraft propulsion systems. Herein referred to as the Adapted Mechanical Pressure Regulator (APR), the regulator is an adaptation made by the Swedish space system developer OHB Sweden AB (OSE) of an existing patented design originally intended for use outside of the space industry.

5. Modified lignin as replacement of carbon black in elastomers- For the development of sustainable tyre technology : The substitution of carbon black with modified lignin- Green tyre technology
Master-uppsats, Karlstads universitet/Avdelningen för kemiteknikSammanfattning : Due to its large flexibility, low-price, large availability, and properties lignin is seen as an important compound with a wide range of applications. The increasing demand of fossil-based rubber materials is causing a serious threat to the environment and it is contributing to plastic- and marine pollution, ozone depletion and carbon dioxide emission (CO2) [1,2].
