 The study characterizes the physical, chemical, structural, crystallographic, thermal and surface topographical properties of fiber extracted from the steam of Iconia crassipes, EC, plant for the first time, revealing that it has lower density and higher cellulose content. FTIR, XRD, TGA, and DSC analyses established that ECF is a suitable substitute for artificial fibers used in fiber-reinforced plastics due to its thermal stability up to 200 degrees celsius.
