Abstract Natural fiber reinforced green composites have been attracting high attention nowadays, as the green movement in the world forced companies to use green materials instead of synthetic fibre reinforced composites. In this respect, the aim of the study is to investigate usage possibility of undervalued Chrysanthemum morifolium stem fibers as a new reinforcement of composite materials. Chemical, thermal, crystallographic, density, mechanical and morphological characterizations of the C. morifolium fibers were examined. Crystallinity Index, density and tensile strength values were found as 65.18%, 1.33 g/cm3 and 65.12 MPa, respectively. Chrysanthemum morifolium has a low cellulose content of 32.9% while the thermal resistance temperature was determined as 267.5 °C. Although its cellulose content is low, C. morifolium fiber can be a good alternative for many other reinforcement plant fibers in terms of tensile strength. The high tensile strength of the fiber can be attributed to the high crystallinity index and fiber morphology advantage (low lumen diameter and thick cell wall). Hollow fiber morphology can increase the insulation and absorption properties of the fibers and can also R. Dalmis (&) S. Koktas O. Y.

Introduction Since the early ages, metallic materials based on ferrous and non-ferrous have been used in the production of advanced technology vehicles such as aircraft from the simplest equipment. The need for lighter and stronger materials led to the development of composite materials after the discovery of polymers with low-density (Karthi et al. 2020). The green movement in the world forced automotive companies to use bio-composite green materials instead of synthetic fibre reinforced composites (Ganapathy et al. 2019; Senthamaraikannan and Kathiresan 2018). Due to high cost-effectivity, sustainability, recyclability of the natural fiber-reinforced composites, high demand occurred in the last 20 years for natural fiber-reinforced polymeric composites in the fields of building and industrial panels, false ceilings, storage devices, automobile body panels,
