   University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen; Lunds universitet/Lunds Tekniska Högskola

   Author : Linus Bengtsson; [2023]
   Keywords : Micromechanical characterization; SEM; In situ tensile testing; Paper deformation; Fiber orientation; Paper mechanics; Technology and Engineering;

   Abstract : Hur ser framtidens hållbara förpackning ut och vad är den tillverkad av? För att besvara denna fråga blir mikromekanisk karakterisering av material en viktig parameter att utforska och förstå. I synnerhet är mikromekaniken hos tunna pappersmaterial intressant då materialet har användningspotential i flera förpackningsapplikationer. READ MORE

3. 2. Mechanical characterization of DuraPulp by means of micromechanical modelling

   University essay from Linnéuniversitetet/Institutionen för byggteknik (BY); Linnéuniversitetet/Institutionen för maskinteknik (MT)

   Author : Mustafa Al-Darwash; Emanuel Nuss; [2015]
   Keywords : Natural fiber composites NFC ; Polylactic acid PLA ; Micromechanical modeling; Modulus of Elasticity MOE ; Shear modulus; Poisson’s ratio;

   Abstract : Södra DuraPulp is a relatively new eco-composite, made from natural wood fibers and polylactic acid (PLA), which comes from corn starch. Until now, there are only few applications for DuraPulp, mainly in the area of design. To find new fields of application, more knowledge about its mechanical material properties are of great interest. READ MORE

4. 3. Micromechanical Numeric Investigation of Fiber Bonds in 3D Network Structures.

   University essay from KTH/Hållfasthetslära (Avd.)

   Author : YAĞIZ AZİZOĞLU; [2014]
   Keywords : Finite element; strength additive; 3D model; fiber network model; contact stiffness; paper strength; AFM; fiber adhesion.;

   Abstract : In manufacturing of paper and paperboard, optimized fiber usage has crucial importance for process efficiency and profitability. Dry strength of paper is one of the important quality criteria, which can be improved by adding dry strength additive that affect fiber to fiber bonding. READ MORE
