Article.
Accés obert
In this research, the influence of the macro- and micro-topography on randomly micro-textured polypropylene surfaces has been studied. An initial characterization of the underlying surface was carried out using three-dimensional ...
Multivariate identification of extruded PLA samples from the infrared spectrum
(Springer, 2020-01)
Article.
Accés obert
Article.
Accés obert
Polylactic acid (PLA) is a biodegradable thermoplastic polymer that is presented as a good alternative to petroleum-derived plastics. Some of the major drawbacks of this material are its lack of thermal stability and rapid ...

Influence of topographical features on the surface appearance measurement of injection moulded components
(Elsevier, 2021-01)
Article.
Accés obert
Article.
Accés obert
Adding textures to surfaces is known to improve the external appearance of injection moulded components. However, when high surface quality is required, normally a paint coating is applied on top of the moulded textured ...
