  1. 11. Image-based numerical modelling of heterogeneous materials

    Författare :Robert Auenhammer; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; X-ray computed tomography; image analysis; image-based modelling; Composites;

    Sammanfattning : In science there has always been a desire to visualise the invisible. Since the discovery of X-rays in 1895, imaging research has made remarkable progress. Nowadays, state-of-the-art technology allows to visualise the micro-structure of objects in three dimensions. However, merely visualising the structure is often insufficient. LÄS MER

  3. 12. Joining of Carbon Fibre Reinforced Plastics for Automotive Applications

    Författare :Gordon Kelly; KTH; []
    Nyckelord :Composite; laminate; bearing strength; joining; load introduction; hybrid joint; finite element analysis; mechanical testing;

    Sammanfattning : The introduction of carbon-fibre reinforced plastics in loadbearing automotive structures provides a great potential toreduce vehicle weight and fuel consumption. To enable themanufacture and assembly of composite structural parts,reliable and cost-effective joining technologies must bedeveloped. LÄS MER

  4. 13. Compressive failure of unidirectional NCF composites

    Författare :Dennis Wilhelmsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aerospace; Fibre misalignment; Compressive failure; NCF composite;

    Sammanfattning : With more people flying every year, new technologies are needed to reduce our impact on the environment. One option is to reduce the energy used in flight by introducing lighter materials such as carbon fibre reinforced polymers (CFRP). LÄS MER

  5. 14. Impact Loading of Composite and Sandwich Structures

    Författare :Sohrab Kazemahvazi; Dan Zenkert; Guruswami Ravichandran; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fluid mechanics; Strömningsmekanik;

    Sammanfattning : Low weight is one of the most important factors in the design process of high speed naval ships, road vehicles and aircrafts. Lower structural weight enables the possibility of down-sizing the propulsion system and thus decrease manufacturing and operating costs as well as reducing the environmental impact. LÄS MER

  7. 15. On matrix-driven failure in unidirectional NCF composites - A theoretical and experimental study

    Författare :Dennis Wilhelmsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NCF composite; aerospace; compressive testing; compressive failure;

    Sammanfattning : With ever increasing traffic levels, the civil aircraft industry is in constant need of new technologies to make air travel environmentally sustainable. One such technology is light materials to reduce the energy consumption in flight. LÄS MER
