Abstract
Some of the widely used processes for fabricating fiber reinforced composites, require that a high viscosity liquid resin be forced to penetrate a dense fibrous network (woven or nonwoven). Incomplete penetration of the network by resin leads to unsupported regions of fibers and to permanent entrapment of air (voids) in the cured product. Such structural imperfections have detrimental effects on mechanical properties due to reduced stress transfer between fiber and matrix. Voids also act as stress-concentration sites and promote premature failure of the composite. This paper will summarize some of our studies on the flow of model liquids into fiber networks in order to determine the factors that control air entrapment.
