STUDY ON A NOVEL PHENOLIC RESIN AND ITS COMPOSITES FOR PULTRUSION PROCESS

Abstract

Abstract: A novel non-acid phenolic resin named F-613 for pultrusion process was studied. The structure, molecular weight, viscosity, curing properties and gelling time of this resin were characterized by FTIR, GPC, rheometer, DSC and etc. The DSC curve of F-613 phenolic resin displayed a single exothermic peak existing lower temperature area contrast to 9450 phenolic resin with two exothermic peaks in higher temperature area. Moreover, F-613 phenolic resin retains shorter gel-time at high temperature. The analysis results indicated that F-613, with shorter gel-time and lower exothermic peak temperature, is more applicable to pultrusion process because of its low viscosity, high activity and rapid solidification. Compared with that of 9450 phenolic resin, the formula and pultrusion process of F-613 were simpler under the condition of the same properties. The mechanical properties of glass fibre-reinforced composites shows no significant differences. But, the distinct properties of F-613 phenolic resin systems is no corrosion to mould during the pultrusion process.

Key words: phenolic resin, pultrusion process, composites
