Montmorillonite Nanoclay

This work aims to explore the effect of organo-modified montmorillonite nanoclay (O-MMT) on the mechanical, thermo-mechanical, and thermal properties of carbon fiber-reinforced phenolic composites (CFRP). CFRP at variable O-MMT contents (from 0 to 2.5 wt%) were prepared. The addition of 1.5 wt% O-MMT was found to give the heat resistant polymer composite optimum properties. Compared to the CFRP, the CFRP with 1.5 wt% O-MMT provided a higher tensile strength of 64 MPa (+20%), higher impact strength of 49 kJ/m2 (+51%), but a little lower bending strength of 162 MPa (−1%). The composite showed a 64% higher storage modulus at 30 °C of 6.4 GPa. It also could reserve its high modulus up to 145 °C. Moreover, it had a higher heat deflection temperature of 152 °C (+1%) and a higher thermal degradation temperature of 630 °C. This composite could maintain its mechanical properties at high temperature and was a good candidate for heat resistant material.

The poly (ethylene terephthalate)/poly (trimethylene terephthalate) (PET/PTT) blends were prepared and their phase morphology, mechanical and thermal properties were investigated by scanning electron microscopy (SEM), polarized optical microscopy (POM), universal material testing machine, differential scanning calorimetry (DSC), wide-angle X-ray (WAXD), respectively. The glass transition and SEM results suggest apparently that the PET and PTT have good miscibility at amorphous state. The blends with more PET content less likely undergo a melting/recrystallization process during DSC heating scan. In the blends, PET component with higher supercooling degree crystallizes first, and then the crystallites of PET will be the nucleating agents for PTT, which greatly improves the crystallization rate of PTT. Because of the interaction between the PET and PTT, there are much smaller spherulites formed in blends with increasing PET component. The blend with more PET contents has larger tensile strength and modulus.

The use of nanofillers to enhance the properties of fiber reinforced composites is limited due to the adverse effect on mechanical properties caused by agglomeration of these nanofillers in the matrix materials. In this study, graphene nanoflakes were functionalized with silane moiety to improve its dispersion, stability and bond strengths in the polymer matrices of the carbon fiber reinforced composites. Wet layup process was applied to incorporate graphene nanocomposites into the dry carbon fibers to make composite panels following the curing cycle of the epoxy and hardener. The impacts of the functionalized graphene on the mechanical and thermal properties of carbon reinforced composite were investigated in detail by tensile test, differential scanning calorimetry, dynamic mechanical analysis and scanning electron microscopy (SEM) analysis. It was observed that nanocomposites with 0.5 wt% silanized graphene exhibited maximum tensile strength and modulus of elasticity, indicating that 0.50 wt% silane functionalized graphene was the optimum nanofiller composition amongst the three different compositions investigated. The nanocomposites with 0.25 wt% and 0.50 wt% nanofillers showed improved ductility compared to the control sample. Based on the SEM studies on the crack zones, major morphological changes were observed after the salinization process. The interfacial interaction between epoxy and silane moiety of the graphene and reduction in the tendency to agglomerate could account for the improved properties of the nanocomposite observed here. Nanocomposites with silanized graphene showed overall higher glass transition temperature (Tg) and tensile strength than those with pristine graphene and control samples.
