Basic mechanical analysis of biodegradable materials

Abstract

The field of polymeric materials and manufacturing technologies is constantly evolving, offering the possibility to prototype 3D products in a responsible and ecological way, thus aiming to replace on a large scale the filaments of nonbiodegradable synthetic polymers (from fossil resources) with filaments of biodegradable materials, obtained from renewable resources. The paper supports the development mentioned above and follows to characterize biodegradable materials from the mechanical behavior point of view, tensile, bending, and impact tests. Also, the study reflects the influence of the technological parameters on the tensile test obtained results and also aims to optimize the obtained results. The studied materials were Extrudr Green-TEC Anthracite and Extrudr BDP Pearl which according to the obtained basic mechanical results can successfully replace conventional polymers such as Flexible, HIPS, PP and other ones.

Characterization of Arboblend V2 Nature Textured Surfaces Obtained by Injection Molding

“…The material of the samples used for texturing is Arboblend V2 Nature, a biopolymer patented by a team of researchers from the Fraunhofer Institute for Chemical Technology (ICT) in Pfinztal (Germany) in collaboration with the company Tecnaro GmbH, showing great potential for use in industrial applications from all fields that use renewable resources and whose content is based on biopolymers, such as polyhydroxyalkanoates (PHAs), polycaprolactone (PCL), polyester (e.g., bio-PET), starch, polylactic acid (PLA), bio-polyolefins (bio-PEs), bio-polyamides (bio-PAs), lignin, natural resins, natural waxes, natural oils, natural fatty acids, cellulose, organic additives and natural reinforcing fibers [ 22 ]. The basic properties of the Arboblend V2 Nature material are presented in Table 1 [ 23 ], and a number of authors have studied this material both from the point of view of mechanical and thermal properties and have also analyzed its structure [ 24 , 25 , 26 , 27 , 28 , 29 ].…”

Morphological, mechanical, magnetic, and thermal properties of 3D printed functional polymeric structures modified with Fe2O3 nanoparticles

“…AM technologies have also provided a great advantage in upstream energy consumption by eliminating processing steps and scrap material features. [15][16][17] The most widely preferred AM methods are stereolithography (SLA), [18,19] digital light processing (DLP), [20,21] fused deposition modeling (FDM), [22,23] selective laser sintering (SLS), [24,25] and selective laser melting (SLM). [26,27] SLA, one of the extremely advanced AM techniques, is widely used in the production of high-resolution polymeric structures.…”
