ANALYSIS OF THE CHEMICAL RHEOLOGICAL BEHAVIOR AND MODELING OF THE PHENOLIC RESOL RESIN FOR VARTM PROCESSES

Abstract

Abstract: A new kind of phenolic resol resin named Z615101, was developed for vacuum assisted resin transfer molding process (VARTM). The resin has the advantages of higher char yield, lower initial viscosity and longer pot life of the process as compared to conventional phenolic resol resin. It is suitable for manufacturing advanced fiber-reinforced composite materials ranging from smallarticles of simple shape, to large articles with complex shape and high structural performance characteristics, especially large complex three-dimensional part of advanced composite materials for aerospace application. The rheological behavior of phenolic resol resin was studied. The curve of dynamic viscosity-temperature for Z615101 was also studied. The Arrhenius viscosity equation was established based on the measured isothermal viscosity curves. Analysis results indicated that the model values were in good agreement with the experimental results. The optimal processing temperature window was between 70~80 ℃ learned from the isothermal viscosity curves, which were established on the basis of model equation and would provide the theoretical foundation for the actual VARTM processing molding.

Key words: phenolic resol resin, VARTM processes, chemical rheological behavior, composites, proce-ssing window
