Sammanfattning : The scope of this thesis is to quantitatively investigate the molecular orientation distribution of regenerated cellulose fibers and composites. The molecular orientation is known to affect macroscopic properties such as tensile strength of the fiber. LÄS MER
Sammanfattning : This thesis explores the integration of electrospun polymeric structures in two fields; fibrous scaffolds as cell culture substrates for biomedical applications and fiber carrier networks in metal matrix polymer composites as thermal interface materials in microsystems. Electrospinning has been found to carry great potential for a range of future biomedical engineering applications. LÄS MER

Sammanfattning : Flax fibers, along with a number of other natural fibers, are being considered as an environmentally friendlier alternative of synthetic fibers in fiber-reinforced polymer composites. A common feature of natural fibers is a much higher variability of mechanical properties. LÄS MER
Sammanfattning : Paper is used in a wide range of applications, each of which has specific requirements on mechanical and surface properties. The role of paper strength on paper performance is still not well understood. This work addresses the mechanical properties of paper by utilizing fiber network simulation and consists of two parts.
