Reinforcement Efficiency

In the present investigation, carbon nanofibers (CNF) were dispersed in epoxy matrix to form CNF/glass fiber/epoxy composites. Before blending, CNF was oxidated to get more functional groups on CNF and improve the interface combination between resin and CNF, the infrared spectrum was used to test the efficiency. After that, tensile modulus tests were carried on for CNF/glass fiber/epoxy composites with different CNF fractions, the results indicated that there were slight improvements of tensile modulus when adding CNF. At 3.0 wt% of CNF, composites have the high improvement of tensile modulus, but the reinforcement of CNF decreased at 5.0 wt% of CNF. And the CNF reinforcement efficiency was analyzed using modified Coxs model and rule of mixture.

In this paper, glass fiber reinforce polymer subject to quasi-static three point bending loading and tensile loading was studied experimentally. Glass fiber reinforced made of chopped strand mat (CSM) were used in this study. Several samples were prepared and tested by using Instron universal testing machine at different strain rate including 1mm/min, 10mm/min and 100mm/min and all of the tests were repeated three times in order to minimize experimental error and the average of the obtained results were used for further analysis. The load-extension curves and stress-strain curve of glass fiber reinforce subject to three point bending and tensile loading test were determined at different strain rate and the obtained results were compared together. As results of this study, it has found that the strain rate has effect on flexural and tensile behavior of glass fiber reinforce.

In this study, we report the synthesis of uniform and narrowly size-distributed ZnO nanoparticles with sizes of approximately 3 nm; the nanoparticles were prepared by means of organic-ligand-assisted hydrothermal conditions with various organic modifiers. The results obtained herein revealed that among the various functional groups tested (alcohols, aldehydes, carboxylic acids, and amines), only hexanol effectively controlled the nucleation and crystal growth of spherical ZnO nanoparticles. The use of hexanol also caused the surface of the ZnO particles to change from hydrophilic to hydrophobic, which would enhance the dispersion of these particles in polymer matrices, paints, cosmetics, and other organic application media.
