The composite production has been commonly researched because of its crucial properties such as low density, light weight, having better mechanical behaviors, and stifness. There are numerous uses in marine, automotive, sporting, and aerospace industries. In this study, fber-reinforced composites were produced with Alcea Rosea L. fber and epoxy resin. Besides, an image processing technique was proposed and put into use to specify the average fber thickness of Alcea Rosea L. fber. The composites were prepared at 5:95, 10:90 fber:epoxy resin weight percentages. Before the composite synthesis, Alcea Rosea L. fbers were treated to alkali surface modifcation with 10% sodium hydroxyl for 30 min. The thermal conductivity coefcient, sound absorption coefcient, and tensile strength of composites were measured. The thermal conductivity coef fcient of samples decreases with increase in Alcea Rosea L. fber weight percentage. The sound absorption coefcient and mechanical properties of samples improve with increase in Alcea Rosea L. fber weight percentage. These results show that Alcea Rosea L. fber-reinforced sustainable composites can be used as a potential thermal and acoustic insulator.
