Abstract

Abstract: A room temperature liquid tackifier for vinyl ester resin was developed for the preparation of preforms, and the composite material was prepared by VARI molding process. The effects of tackifier content on fiber fabric setting effect, VARI molding processability and mechanical properties of composites were studied. The setting effect of the tackifier was evaluated by the experimental methods of thickness rebound and U-shaped rebound; the VARI molding processability of the setting fabric was evaluated by the permeability test of the preform; and the mechanical properties of the composites were characterized by bending and interlaminar shear tests. The results show that when the content of the tackifier is 6wt% of the fiber fabric, the presetting of the fabric is the best, and it can maintain a good permeability; the amount of the tackifier has little effect on the bending properties and interlaminar shear properties of the composites, which can improve the manufacturability and achieve no significant decrease in the mechanical properties of the composite material.

Key words: room temperature tackifier, vinyl ester resin composite, VARI molding process, bending, interlaminar shear
