EFFECT OF DIFFERENT NON-WOVEN FABRICS ON MECHANICAL PROPERTIESOF GLASS FIBER/VINYL ESTER COMPOSITES

Abstract

Abstract: In order to improve the interlaminar properties of glass fiber/vinyl ester (GF/VE) composites, GF/VE composites with polyamide (PA), copolyester (PEs), polyurethane (TPU) and vinyl acetate (EVA) nonwoven fabrics were prepared by VARI process. The tensile, flexural and mode Ⅰ interlaminar fracture toughness of the composites were studied. The results show that the mode Ⅰ interlaminar fracture toughness of GF/VE composites increases by 142%, 103%, 46% and 45%, respectively, by adding PEs, TPU, PA and EVA nonwoven fabrics. The tensile strength of GF/VE composites increased by 6.43% by adding TPU non-woven fabrics, while the others decreased by 2.93%, 3.72% and 28.67%, respectively. After adding different non-woven fabrics, bending strength decreased by 13%, 14%, 25% and 60%, respectively. The strengthening and toughening effects of co-polyester and polyurethane nonwoven fabrics on GF/VE composites are better than that of polyamide materials.

Key words: GF/VE composites, non-woven fabrics, interlaminar toughening, mechanical properties, mode Ⅰ interlaminar fracture toughness
