 This paper reports the physical, chemical, and thermal properties of cellulosic fibers extracted from cedar-acuta stem, as well as the mechanical properties of cedar-acuta fiber-reinforced epixie composite added with fly-ash filler. The results show that SAFs have high cellulose content, tensile strength, crystallinity index, and thermal stability. The composite with 2% fly-ash exhibits superior mechanical properties compared to other samples, and the surface morphological changes of fiber matrix interface due to fly-ash are confirmed through field emission-scanning electron microscope images.
