   Sammanfattning : The purpose of the study is to contribute knowledge about children's understanding of the physical phenomenon of friction by conducting a planned learning activity together with the children. In the activity, the children had the opportunity to investigate high and low friction with varied materials in a slide. LÄS MER

4. 3. Tribology of Polymer Composite with Low Load Application for Automotive Industries

   Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Författare :Martin Asuquo; [2022]
   Nyckelord :;

   Sammanfattning : In recent times, there has been an increased interest in replacing conventional metals and synthetic fiber composites in various automobile parts with natural fiber polymer composites. These natural fiber composites offer benefits over conventional materials in terms of reduction in weight, lower cost, comparable high specific properties such as specific stiffness and strength, low abrasion property, and availability of these materials.
