“…For instance, Foster et al [37] investigated the incorporation of carbon nanofibres (CNF) into hot compacted polypropylene (PP) woven tapes and also the addition of other nano and micro--sized fillers, such as talc, nanoclay, fly ash and carbon black [35]. It was reported that all of the fillers improved the interlayer adhesion properties compared to the pure PP tape/film, which was confirmed via SEM images and peel testing.…”

Abstract:Self--reinforced polylactic acid (SR PLA) composites incorporating cellulose nanowhiskers (CNWs) were produced by coating orientated PLA fibres with a polyvinyl acetate (PVAc)--CNW mixture as a binder prior to hot compaction at 95 o C. PLA fibres were produced with an average diameter of 11 (± 0.9) µm via a melt--drawing process at 180 o C. Scanning electron microscopy (SEM) images revealed that the CNWs imparted roughness to the PLA fibre surface. Cross--sectional examination of the SR PLA composites after hot--pressing confirmed that the PLA fibres had maintained their morphology.Incorporation of 8 wt% CNWs within the SR--PLA composites revealed an increase in their flexural strength (48%) and modulus (39%) compared to the control composite (flexural strength~82 MPa and modulus~3.9 GPa). In addition, whilst the control SR--PLA composite revealed quite brittle characteristics, the addition of CNWs and PVAc gave the self--reinforced composite a more ductile behaviour.

“…Samples were cut directly from the hot compacted sheet in 10mm wide strips. Peel tests were performed at a rate of 80mm/min (rate as in previous work [2,3]), at a room temperature of 21±1°C and RH of 50%. The peel load was determined as the average force required to propagate the delamination of the hot compacted layers for the 10mm wide strip.…”

“…Recent research on the self-reinforced single polymer composites produced by the Leeds hot compaction method has been focused on the enhancement of the material properties, both through modification and enhancement of the hot compaction technique [1] and also through trials of new materials, including the incorporation of nanoscale fillers [2][3][4]. In addition to improving the more usual mechanical properties (e.g.…”

“…It has been previously reported that the incorporation of carbon nanofibres (CNF) into hot compacted polypropylene woven tapes (without interleaved films) resulted in an improved peel strength [2]. Another study [1] has shown the advantage of using unfilled thin film layers, of the same polymer, interleaved between the woven tape layers, resulting in greatly enhanced peel strength since the film layer introduces more matrix material at the point required -the interlayer region.…”

The filler initially chosen for this study was talc, but a number of other fillers have also been investigated. Scanning electron microscopy has been used to image the peel surfaces and to undertake a preliminary study of the effects of particle size and shape on the peel strength.2

Effect of heat treatment of carbon nanofibers (CNF) on electrical properties and crystallization behavior of polypropylene was reported. Two types of CNFs (untreated and heat treated at 2300 °C) were incorporated into polypropylene (PP) using intensive mixing. A significant drop in volume resistivity was observed with composites containing untreated 5 wt % and heat treated 3 wt % CNF. In non-isothermal crystallization studies, both untreated and heat treated CNFs acted as nucleating agents. Composites with heat treated CNFs showed a higher crystallization temperature than composites with untreated CNFs did. TEM results of CNF revealed that an irregular structure of CNFs can be converted into the continuous graphitic structure after heat treatment. Furthermore, STM showed that the higher carbonization temperature leads to the higher graphite degree which presents the larger carbon network size, suggesting that a more graphitic structure of CNFs led to a higher crystallization temperature of PP.
