INFLUENCE AND CONTROL OF PARAMETERS ON THE COMPOSITE FIBERVOLUME FRACTION BY VARI PROCESS

Abstract

Abstract: The composite laminates were manufactured by VARI technology with different preform and infusion parameters, and the effect of the technology parameters to the fiber volume fraction are investigated. The results show that the fiber volume fraction of the composite laminate can be improved through the way of increasing resin over infusion and over vent time, decreasing the resin viscosity or increasing the preform pressure. With the above methods, the fiber can be re-configurated for longer time so that the fiber can be compacted more deeply. The fiber volume fraction can reach to 57.1% for the compacted laminate by VARI manufactuing process.

Key words: over infusion, over vent, pressure, viscosity, fiber volume fraction
