Prototip culata del vehicle de baix consum (equip EPS-UdG Shell Eco)

Aquest projecte s’ha portat a terme per tal de millorar en diferentsaspectes el motor Honda Gx35 , del vehicle de baix consum de la Universitat deGirona (Udg). Aquest és un motor de combustió interna de gasolina (cicle Otto).L’objectiu és el disseny d’una culata per poder minimitzar el consum de gasolina, la qual s’ha de poder acoblar amb el motor Honda Gx35. Aquest motor,prèviament s’haurà de modificar per poder-hi instal•lari la nova culata

Management of corn stalk waste as reinforcement for polypropylene injection moulded composites

The main objective of this study was the management of corn stalk waste as reinforcement for polypropylene (PP) injection moulded composites as an alternative to wood flour and fibers. In the first step, corn stalk waste was subjected to various treatments, and four different corn stalk derivatives (flour and fibers) able to be used as reinforcement of composite materials were prepared and characterized. These derivatives are corn stalk flour, thermo-mechanical, semi-chemical, and chemical fibers. They were characterized in terms of their yield, lignin content, Kappa number, fiber length/diameter ratio, fines, coarseness, viscosity, and the length at the break of a standard sheet of paper. Results showed that the corn stalk derivatives have different physico-chemical properties. In the second step, the prepared flour and fibers were explored as a reinforcing element for PP composites. Coupled and non-coupled PP composites were prepared and tested for tensile properties. For overall trend, with the addition of a coupling agent, tensile properties of composites significantly improved, as compared with non-coupled samples. In addition, a morphological study revealed the positive effect of the coupling agent on the interfacial bonding. The composites prepared with semichemical fiber gave better results in comparison with the rest of the corn stalk derivatives due to its chemical characteristics
