Hybrid carbon fibre–carbon nanotube composite interfaces

Abstract: Both low and high modulus carbon fibres are coated with carboxylated single wall carbon nanotubes (SWNTs). It is shown that it is then possible to follow, for the first time, the local deformation of low modulus carbon fibres and composite interfaces using Raman spectroscopy. By deforming coated single carbon fibre filaments in tension, and following the shift in the position of a band located at ~2660 cm -1 (2D band) it is possible to calibrate the local stress state of a fibre embedded in an epoxy resin.

“…Among, the properties of PP matrix and CF filler, the interfacial adhesion strength between PP and CF are the main factors, determining the ultimate toughness of PP/CF composites . Many researchers paid increasing attention to enhancing interfacial interaction by grafting function groups on PP and CF surface . Although these modification strategies are effective on toughening PP/CF composites, they usually have complex modification process or damages to CF inherent mechanical properties by oxidization of concentrated H 2 SO 4 and HNO 3 .…”

“…Destacam-se nessas nanopartículas a elevada resistência mecânica, condutividade elétrica, dependendo de sua estrutura, e resistência térmica. Muitos estudos de nanocompósitos envolvendo nanotubos tem sido realizados em função destas propriedades (Gardea e Lagoudas, 2014;JIN et al, 2014;Shokrieh et al, 2014). Por sua vez, o poli(cloreto de vinila) [PVC] é um polímero de grande interesse industrial, destacando-se como o segundo termoplástico de maior consumo no mundo.…”

“…Os nanotubos de carbono (NTC) foram descobertos em 1991 por Sumio Ijima (Ijima, 1991) e desde então, muita atenção vem sendo dedicada a este material devido ao seu grande potencial de aplicação e extraordinárias propriedades físicas, químicas e elétricas (Antonucci et al,2003). Muitos estudos de nanocompósitos envolvendo nanotubos de carbono tem sido realizados em função destas propriedades (Gardea e Lagoudas, 2014;Jin et al, 2014).…”
