2. 1. Development of Constituents for Multi-functional Composites Reinforced with Cellulosic Fibers

   Author : Zainab Al-Maqdasi; Roberts Joffe; Nazanin Emami; Liva Pupure; Yvonne Aitomäki; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cellulose fibers; multi-functional; composites; nano-reinforcement; thermoplastics; development; Polymeric Composite Materials; Polymera kompositmaterial;

   Abstract : Bio-basedcomposites are being increasingly used in applications where weight saving,and environmental friendliness is as important as structural performance. Obviously, bio-based materials have their limitations regarding durability and stability of the properties,but their potential in use for advanced applications can be expanded if they were functionalized and considered beyond their structural performance.

7. 5. Opportunities for Weight Reduction in Composite Marine Structures

   Author : Luis Felipe Sanchez Heres; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; material characterization; ultimate limit state; composites; lightweight design; non-crimp fabrics;

   Abstract : Composite marine structures are desirable for a variety of reasons. Compared to traditional steel structures, they enable the construction of vessels with lower fuel consumption, higher top speed, better stability, lower maintenance, higher cargo capacity, or combinations thereof.
