Piezoresistive modelling of CNTs reinforced composites under mechanical loadings

Nano-engineered Composites Reinforced with Aligned Carbon Nanotubes (CNTs)

We present the implementation of aligned carbon nanotubes (CNTs) as a method to enhance properties of traditional advanced composites. The hybrid composites are 3-dimensional architectures of aligned CNTs, and existing advanced fibers and polymeric resins creating nanoengineered composites. Our work to date has focused on interlaminar strength and toughness, and electrical and thermal conductiv...

Stress-strain Response Modelling of Glass Fibre Reinforced Epoxy Composite Pipes under Multiaxial Loadings

This paper presents the modelling of stress strain response of glass fibre reinforced epoxy (GRE) composite pipes subjected to multiaxial loadings at room temperature (RT). This particular modelling work was developed to predict the non-linear stress strain response caused by the fatigue cyclic and static loading in the multiaxial ultimate elastic wall stress (UEWS) tests by considering the eff...

Study on Mechanical Properties and Constitutive Equation of Hybrid Fiber Reinforced Cementitious Composites Under Static Loading

Abstract: The Quasi-static mechanical properties of hybrid fiber (steel fiber and Polyvinyl alcohol (PVA) fiber) reinforced cementitious composites (HFRCC(SP)) were investigated by compressive and tensile experiments. The compressive strength, peak strain, elastic modulus and tensile strength are studied as compared with that of engineered cementitious composite (ECC). Study results indicate th...

Nanoscaled Mechanical Properties of Cement Composites Reinforced with Carbon Nanofibers

This paper reports the effects of carbon nanofibers (CNFs) on nanoscaled mechanical properties of cement composites. CNFs were added to cement composites at the filler loading of 0.2 wt % (by wt. of cement). Micrographs based on scanning electron microscopy (SEM) show that CNFs are capable of forming strong interfacial bonding with cement matrices. Experimental results using nanoindentation rev...
