  1. 21. Redesign for Carbon Fiber : A feasibility study on composites in forestry harvesting heads

    University essay from Linköpings universitet/Produktrealisering

    Author : Simon Karlsson; Isabella Marklund; [2021]
    Keywords : Redesign; Single Grip Harvesting Head; Forestry; Composite Design; CFRP;

    Abstract : Harvesting heads are an essential part of today’s forestry industry, enabling a high rate of tree felling from a single operator. Requirements for the forestry machine they are attached to are strongly linked to the weight of the harvesting head, providing an incentive to make the heads as light as possible. READ MORE

  2. 22. Bio-oil based polymeric composites for additive manufacturing

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Suvi Muukka; [2020]
    Keywords : polymer composite; polyamide; glass fiber; microcrystalline cellulose; composite; compatibilization; additive manufacturing; polymeerikomposiitti; polyamidi; lasikuitu; mikrokiteinen selluloosa; kompatibilisaatio; materiaalia lisäävät menetelmät; polymerkomposit; polyamid; glasfiber; mikrokristallin cellulosa; kompatibilisering; additiv tillverkning;

    Abstract : Plast- och kompositindustrin har växt i årtionden och den ständigt växande världen och ny teknik kräver ännu större mängder polymerkompositer för en mängd olika tillämpningar. Numera är de negativa miljöaspekterna av polymerproduktion och plastavfall kända, men trots detta är råoljafortfarande det primära råmaterialet för de flesta polymerer. READ MORE

  3. 23. Effect of Induction-Heat Post-Curing on Residual Stresses in Fast-Curing Carbon Fibre Reinforced Composites

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Mercedes Amelia Bettelli; [2020]
    Keywords : Carbon Fibres Reinforced Polymer Composite; epoxy resins; cure behaviour; residual stress and shape distortions;

    Abstract : Manufacturing induced shape distortions is a common problem for composite materials. Due to the non-isotropic nature of carbon fibre reinforced polymers (CFRP) unavoidable deformations occur during part production. During fabrication of polymer composites, the material obtains its final shape at elevated temperatures. READ MORE

  4. 24. Adhesive modelling in multi-material structures : Evaluating the strength and fatigue life of adhesive joints

    University essay from Linköpings universitet/Mekanik och hållfasthetslära

    Author : Nitin Narayanaswamy; [2020]
    Keywords : Adhesive Joints Strength Calculation J Integral Method Energy Release Rate Theory Crack Finite Element Analysis Multi Material Structures Automotive;

    Abstract : Advancements in material science and manufacturing techniques are enabling the use of lightweight metal alloys and polymer composites in several combinations and shapes for producing more efficient and lightweight structures for automotive applications without compromising strength, stiffness and/or durability. When evaluating the strength of the structure, the joints are of importance. READ MORE

  5. 25. Out-of-plane Ferromagnetic Resonance (FMR) measurements on magnetic nanoparticle dispersions for biomedical sensor applications

    University essay from Uppsala universitet/Fasta tillståndets fysik

    Author : Markus Back; [2020]
    Keywords : Ferromagnetic; magnetic; resonance; FMR; EPR; nanoparticle; microwave; coplanar; waveguide; cavity; s-parameter; gilbert; damping; gyromagnetic; liquid; biosensor; landau; lifshits; spin; polymer; composites; engineering physics; teknisk fysik; magnetism; ferromagnetisk; vågledare; resonans; mikrovågsteknik; nanopartiklar;

    Abstract : In this master work, we investigated the feasibility of a magnetic resonance measurement technique using magnetic nanoparticle dispersions in both liquid and solid form. The implementation is realised as a coplanar waveguide operating in the frequency range of 0.5 - 20 GHz and an electromagnet producing a static magnetic field of strength up to 1. READ MORE
