  2. 16. Transverse failure initiation in polymer composites

    Author : Leif Asp; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymeric Composite Materials; Polymera konstruktionsmaterial;

    Abstract : Transverse failure is one of the most important failure modes in polymer composites. The phenomenon often causes the first deviations from nonlinear laminate behavior. Also, in pressure vessels and pipes, fluid leakage through a path of transverse cracks is often the limiting design criterion. READ MORE

  4. 17. Mechanical and Environmental Durability of High Performance Bio-based Composites

    Author : Newsha Doroudgarian; Egidija Rainosalo; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymera konstruktionsmaterial; Polymeric Composite Materials;

    Abstract : 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.

  5. 18. Analysis of transverse cracking in cross-ply laminates: Weibull distribution based approach

    Author : Vivek Richards Pakkam Gabriel; Patrik Fernberg; Mohamed Loukil; Spyros Tsampas; Erik Marklund; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Intralmainar cracking; Weibull distribution; Failure stress; Monte Carlo simulation; Fatigue loading; Quasi-static loading; Polymera kompositmaterial; Polymeric Composite Materials;

    Abstract : Fiber reinforced polymer composite laminates make up more than 50% of modern aircrafts. Such composite laminates are exposed to various environmental and in-service thermo-mechanical load conditions. READ MORE

  6. 19. Wood fiber composites : from processing and structure to mechanical performance

    Author : Lars-Olof Nordin; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymera konstruktionsmaterial; Polymeric Composite Materials;

    Abstract : The work presented in this thesis has been focused on the mechanical properties of wood fiber composites. One goal has been to investigate the processing of wood polymer composite materials with good mechanical properties, and how to tailor these properties for different applications. READ MORE

  7. 20. Inelastic analysis of fiber reinforced polymeric composites

    Author : Modris Megnis; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymera konstruktionsmaterial; Polymeric Composite Materials;

    Abstract : Fiber reinforced polymer composites are seeing increased use in the outomotive industry and other applications. This is because of the potential for rational and economical production in large series of complex shaped parts. Properties such as high strength to weight ratio and superior impact properties are of particular interest. READ MORE
