Title: Mechanical Characterization of Core Shell Rubber Particles Modified Vinyl Ester and Glass Fiber Reinforced Composites
Authors: Swayam Shree and Jitendra S. Tate
Abstract: Glass fiber reinforced Vinyl Composites are wide spread application in the marine and tanks manufacturing industry because of their superior chemical resistance and increased strength over polyester resins. However due to the nature of their cure, vinyl ester resins result in brittle composites and suffer dimensional warping after curing process. This limits their applications where components are subjected to impact and cyclic loading. Introduction of rubber content is known to improve the toughness and strain to failure of thermosetting matrices like vinyl ester. Glass fiber reinforced vinyl ester composites will be manufactured with a vinyl ester-based Core Shell Rubber Particles (CSRP) added as a toughener at three different loading levels. To achieve proper dispersion the Core Shell Rubber Particles were added to the resin matrix using a planetary centrifugal mixer. Composite panels were manufactured using Vacuum Assisted Resin Transfer Molding (VARTM). Tensile, flexural, in-plane shear, compression and Interlaminar shear strength properties of the modified composites were evaluated as per the ASTM standards and compared to unmodified composites.
