Computer-aided design: development of a software tool for solving loci problems
Hernández Díaz, David; Hernández Abad, Francisco; Hernández Abad, Vicente; Villar Ribera, Ricardo Alberto; Julian, Fernando; Rojas Sola, Jose Ignacio (2023)
Article
Open AccessIn this work, we developed a software tool for the simplified, automated definition and viewing of loci in the plane, an essential task in the design, engineering and architectural fields. The process was started by ... -
Effect of extruder type in the interface of PLA layers in FDM printers: filament extruder versus direct pellet extruder
Pagés-Llobet, Antoni; Espinach, Francesc Xavier; Julian, Fernando; Oliver Ortega, Helena; Méndez González, José Alberto (Multidisciplinary Digital Publishing Institute (MDPI), 2023-04-24)
Article
Open AccessFDM (Fused Deposition Modeling) is one of the most used and industrially applied additive manufacturing processes due to its fast prototyping and manufacturing, simplicity, and low cost of the equipment. However, the ... -
Flexural properties and mean intrinsic flexural strength of old newspaper reinforced polypropylene composites
Tarrés Farrés, Joaquim Agustí; Soler, Jordi; Rojas Sola, José Ignacio; Oliver Ortega, Helena; Julian, Fernando; Espinach, Francesc Xavier; Mutjé Pujol, Pere; Delgado-Aguilar, Marc (Multidisciplinary Digital Publishing Institute (MDPI), 2019-07-26)
Article
Open AccessNewspapers have a limited lifespan, and therefore represent a focus of used and disposed paper. While these refuses have a considerable value and can be easily recycled, a considerable fraction ends in landfill. The authors ... -
Impact properties and water uptake behavior of old newspaper recycled fibers-reinforced polypropylene composites
Hernández Díaz, David; Villar Ribera, Ricardo Alberto; Espinach, Francesc Xavier; Julian, Fernando; Hernández Abad, Vicente; Delgado Aguilar, Marc (Multidisciplinary Digital Publishing Institute (MDPI), 2020-02-28)
Article
Open AccessNatural fiber-reinforced thermoplastic composites can be an alternative to mineral fiber-based composites, especially when economic and environment concerns are included under the material selection criteria. In recent ... -
Nanoclay effect into the biodegradation and processability of poly(lactic acid) nanocomposites for food packaging
Oliver Ortega, Helena; Vandermoortele, Victor; Bala, Alba; Julian, Fernando; Méndez González, José Alberto; Espinach, Francesc Xavier (Multidisciplinary Digital Publishing Institute (MDPI), 2021-08-16)
Article
Open AccessOne of the most promising expectations in the design of new materials for food packaging is focused on the development of biodegradable systems with improved barrier character. In this sense PLA reinforced with nanoclay ... -
Nanocomposites materials of PLA reinforced with nanoclays using a masterbatch technology: a study of the mechanical performance and its sustainability
Oliver Ortega, Helena; Tresserras, Josep; Julian, Fernando; Alcalà, Manel; Bala, Alba; Espinach, Francesc Xavier; Méndez González, José Alberto (Multidisciplinary Digital Publishing Institute (MDPI), 2021-06-29)
Article
Open AccessPackaging consumes around 40% of the total plastic production. One of the most important fields with high requirements is food packaging. Food packaging products have been commonly produced with petrol polymers, but due ... -
