Composites of recycled high-density polyethylene and micro fibres of sugarcane bagasse were studied, in order to create an upcycled material to produce masonry bricks. We ranged the polymer/filler ratio from 100–0 to 60%–40%. The materials were assessed through scanning electron microscopy, thermogravimetry/derivative thermogravimetry, differential scanning calorimetry, rheological measurements...

This paper describes researches concerning the use of Wavelength-Division Multiplexing (WDM) techniques over Polymer Optical Fibres (POFs) links for Residential Networks applications. It is reported the development of a 2-channel WDM Multiplexer/Demultiplexer (MUX/DEMUX) device based on a commercially available dichroic beam-splitter operating in the visible spectra. It describes the use of the...

The study analysed the tribological performance of five different polymer composites: polyetheretherketone reinforced with 30% carbon fibres—PEEK CF30, 10% fibres, graphite and polytetrafluoroethylene—PEEK MOD, polytetrafluoroethylene 25% fibres—PTFE CF25, polyoxymethylene fibres—POM CF30 ultra-high molecular weight polyethylene—UHMW PE. polymers were tested under sliding regime a reciprocating...
