6. Modeling the mechanical performance of natural fiber composites
Sammanfattning : Due to environmental concerns the interest in use of renewable and recyclable materials has dramatically increased over the recent years. Wood and other lignocellulosic fiber reinforced polymers have large potential as structural materials due to the high specific stiffness, high specific strength and high aspect ratio of the fibers. LÄS MER
7. On fiber network fracture mechanics and kink band formation in biocomposites
Sammanfattning : This thesis summarizes seven appended papers dealing with: (1) The fracture of fibrous materials, e.g. LÄS MER
8. Betulin-modified cellulosic textile fibers with improved water repellency, hydrophobicity and antibacterial properties
Sammanfattning : Textiles made from natural sources, such as cotton and flax, have advantages over those made of synthetic fibers in terms of sustainability. Unlike major synthetic fibers that have a negative impact on the environment due to poor biodegradability, cotton cellulose is a renewable material. LÄS MER
9. Mechanical and Environmental Durability of High Performance Bio-based Composites
Sammanfattning : This study is an initial step within the on-going project on development of high performance bio-based composites with improved mechanical (fatigue) and environmental (elevated humidity and temperature) durability. In the presented thesis the performance of cellulosic fibers (flax and regenerated cellulose), bio-based resins (Tribest, EpoBioX, Palapreg, and Envirez) and their composites under exposure to elevated humidity has been studied.

10. Non-linear model applied on composites exhibiting inelastic behavior: development and validation
Sammanfattning : The polymeric composite materials are in high demand by industries where light and strong materials are required. Although manmade fiber (e.g. glass, carbon, aramid fibers) are most often used to reinforce polymers, natural fibers due to their environmental friendliness and sustainability have been also considered.
