Effect of single-fiber properties and fiber volume fraction on the mechanical properties of Ioncell fiber composites

The present study concentrates on a series of experiments and numerical analyses for understanding the effects fiber volume fraction ( VF) draw ratio DR) effective elastic properties unidirectional composites made from an epoxy resin matrix with continuous reinforcement. Lyocell-type regenerated cellulose filaments (Ioncell) spun DRs 3, 6, 9 were used. In accordance specimens in situ, fibers modeled as slender solid elements, which between diameter length was taken to be much less than unity deposited inside random sequential adsorption algorithm. embedded element method thereafter used framework due its computational advantages reasonable predictions reinforced composites. Experiments investigations carried out, results compared, positive trends both VFs observed. presented experimental models herein are believed advance state art mechanical characterization
