  1. 11. Quality Assurance of Recycled HDPE in the Plastic Packaging Industry

    University essay from Lunds universitet/Innovation

    Author : Juliana Kalling; Tora Abrahamsson; [2023]
    Keywords : Thermoforming; Plastics; Recycling; Packaging Industry; HDPE; Technology and Engineering;

    Abstract : The recycling of plastic has the potential to support circular material use, thus decreasing the need for virgin plastics. However, there is an existing issue with assuring quality of recycled plastic materials, causing finished products to perform with poorer properties and unexpected deviations. READ MORE

  3. 12. Tomography-based Micromechanical Analysis of Novel Composite Material

    University essay from KTH/Hållfasthetslära

    Author : Mattias Grankvist; [2023]
    Keywords : paper mechanics; micro mechanics; numerical analysis; tomography; foam forming; density profile; pappersmekanik; mikromekanik; numerisk analys; tomografi; skumformning; densitetsprofil;

    Abstract : This study explores the performance of porous Paptic paper materials composed of a mixture of softwood and lyocell fibers. The investigation involves laboratory experiments and numerical simulations to analyse the impact of various parameters on the paper's characteristics. READ MORE

  4. 13. Rate-dependent effects on the mechanical behaviour of paper

    University essay from KTH/Hållfasthetslära

    Author : Satyasarathi Poddar; [2023]
    Keywords : ;

    Abstract : It is established that paper properties depend on the loading rate. The rule of thumb is that the in-plane strength and stiffness increases about 10\%, when the strain rate increases by a factor of 10. Converting of paperboard into packages requires creasing of the paperboard followed by folding to make 3 dimensional packages. READ MORE

  5. 14. Effect of infill density on mechanical and fire properties of polylactic acid composites produced by FDM 3D-printing technology

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : David Aronsson Edström; Oskar Lundberg; [2022]
    Keywords : 3D-printing; FDM; PLA; fire; fire engineering; cone calorimeter; tensile test; UL-94;

    Abstract : 3D-printing is a new and upcoming manufacturing technique that can significantly reduce time and material losses in production. Fused deposition modeling (FDM) is one of the most commonly used 3D-printing methods for processing conventional thermoplastic polymers. READ MORE

  6. 15. Conditioned 3D-printed polyamides for structural optimization : Establishing the material data to advance in AM utilization

    University essay from Uppsala universitet/Tillämpad materialvetenskap

    Author : Philip Olsson; [2022]
    Keywords : Additive manufacturing; selective laser sintering; multi jet fusion; moisture; temperature;

    Abstract : Polyamides are commonly used in additive manufacturing for final part production, but the material performance can be affected by environmental conditions. The purpose of this project was to evaluate the effects of moisture and temperature on 3D printed polyamides and how structural optimization can benefit from condition-specific data. READ MORE
