1. Analysis of transverse composite cross-ply laminates
Abstract : Advanced polymer composites are commonly based on thin prepreg plies stacked at different angles to form a laminate. When the laminate is loaded, intralaminar transverse cracking in off-axis plies is one of the first damage modes. In the presented thesis, cross-ply laminates are used to study the transverse cracking phenomenon. READ MORE

2. Damage accumulation and stiffness degradation in composite laminates
Abstract : In the presented thesis analytical modeling of elastic properties degradation and modeling of damage evolution in composite laminates is performed. Transverse cracking initiation on a fiber/matrix level is briefly studied by testing model composites and cross-ply laminates. READ MORE

3. Degradation of thermo-elastic properties in damaged composite laminates : a theoretical study
Abstract : Fiber composites are today widely used in different load carrying structures. The main reason is their high stiffness and strength to weight ratio. Due to these specific properties they are frequently used in car, marine and space industry. READ MORE

5. Resin transfer moulded composite materials : processing, structure, property relationships
Abstract : This thesis contains analysis of the performance of polymer composites manufactured by resin transfer moulding (RTM). The thesis consists of six papers, where the first two deals with the tensile strength of composites reinforced with randomly oriented glass fibres, which still is the most common reinforcement in RTM manufacturing.
