  1. 6. Impact of wood fibers on the mechanical performance of biocomposite materials

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för byggvetenskaper; Lunds universitet/Hållfasthetslära

    Författare :Jose Maria Moreno Ivañez de Lara; [2021]
    Nyckelord :Biocomposite; Composite; X-ray tomography; Image analysis; Injection moulding; Fracture mechanisms; Technology and Engineering;

    Sammanfattning : Plastics are amazing materials with outstanding properties that make them very useful and cheap for a wide range of uses. However, their pollution to the environment has become one of the main problems to solve in this century. In this Master Thesis biocomposites from Biofiber Tech are studied. LÄS MER

  3. 7. Wear Performance Investigation of Metal Matrix Composite

    Master-uppsats, Lunds universitet/Industriell Produktion

    Författare :Manideep Beri; Hema Kalidasu; [2021]
    Nyckelord :Metal Matrix Composites; Hadfield Steel; Tungsten carbide; Technology and Engineering;

    Sammanfattning : To improve the abrasive wear resistant which is governed by a combination of both high hardness and toughness, WC particles were used to reinforce the Hadfield steel. This latter is known with its good work hardening property. WC is mainly considered for its combination of suitable hardness and toughness. LÄS MER

    Sammanfattning : The challenges faced in today’s industry require materials capable of working in chemically aggressive environments at elevated temperature, which has fueled the development of oxidation resistant materials. All-Oxide Ceramic Matrix Composites (OCMC) are a promising material family due to their inherent chemical stability, moderate mechanical properties, and low weight. LÄS MER

  5. 9. Effects of processing techniques on the microstructure of renewable pulp-fiber reinforced composites and their mechanical performance

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Predrag Jagunic; [2018]
    Nyckelord :composites; mechanical performance; microstructure; renewable; processing techniques;

    Sammanfattning : Commingled composites are stronger than those manufactured with the standard manufacturing method. The objective of the thesis is to answer why that is, to investigate the microstructure of the composites, to model composite strength and compare experimental values with theoretical for composites having poly lactic acid (PLA) as matrix material and composites having poly propylene (PP) as matrix material.
