Mechanical Properties Investigation of Glass/Fiber Reinforced Vinyl Ester/Clay Nanocomposites Fabricated by Vacuum Bag Molding

摘要

This research studies the mechanical properties of two-component and multi-component nanocomposites made by vacuum bag molding. In this study, vinyl ester as a thermoset resin is selected as matrix. Vinyl Ester Resin has been widely used in industries because of its good mechanical and physical properties. In recent years, the mechanical, physical and chemical properties of thermoset resins have been improved with the proper distribution of nanofillers in these resins. Accordingly, at first, the montmorillonite nanoclays are dispersed in the Vinyl Ester Resin with different weight percentages and the mechanical properties of the resulting nanocomposites areexamined. In the next step of this study, the resin containing nanofillers is added to the glass fibers using the vacuum bag method. Finally, the tensile and three-point bending tests are conducted on the standard specimens. Improvement of the mechanical properties of multicomponent nanocomposites compared to the primary composite is one of the important findings of the research which can be used in industrial applications.
