1. 1. Development Of Bio-Based Thermosetting Resins

   University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

   Author : Snehaben Gaurangkumar Mistry; [2021]
   Keywords : Bio-based polymer; Resin; lactide; lactone; isosorbide; butanediol; polymerisation; characterisation; FTIR; NMR; TGA; DMA;

   Abstract : Thermoset polymers are widely used polymers in the world, but Increase in global plastic pollution and lack of fossil fuel stimulates intense research towards environmentally sustainable materials. Bio-based unsaturated polyesters (UPs) would be an excellent solution to replace oil-based synthetic polyesters. READ MORE

3. 2. 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. 3. Biodegradation and ageing of bio-based thermosetting resins from lactic acid

   University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

   Author : Lara Lopes Gomes Hastenreiter; [2019]
   Keywords : bio-based polymer; lactic acid; glycerol; ethylene glycol; pentaerythritol; biodegradation; ageing; characterisation; DSC; TGA; FTIR; tensile;

   Abstract : The need for replacing petroleum-based polymers has been increasing and bio-based polymers prove to be a suitable solution. The aim of this thesis was to synthesize bio-based resins with different chemical architectures to evaluate the effect of the structure on the properties and on their response to ageing and biodegradation.

5. 4. Polyimide thin-ply composite

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

   Author : KHALID MOUANE; [2018]
   Keywords : Polyimide; thin-ply; microcracking; curing stress; mechanical loading;

   Abstract : Mechanical performance of composite structures is influenced by the accumulation of damage from the manufacturing process and throughout the whole service life. For instance, an aircraft is subjected to a combination of mechanical loading and the thermo-oxidative environment from the take-off to the landing. READ MORE
