Utilization of discarded Cymbopogon flexuosus root waste as a novel lignocellulosic fiber for lightweight polymer composite application

The viability of using cellulosic Cymbopogon flexuosus root (CFR) fiber waste from the industry as a reinforcing material in a polyester-reinforced composite was investigated. Initially, CFR anatomy, mechanical, thermal, physio-chemical, morphological, and spectroscopy behaviors were investigated. Spectroscopy and chemical analysis were evidence for the richness of cellulose content (74.33%) in the fiber which reflected in increased tensile strength of 315.22 +/- 61.72 MPa and thermal stability 272.31 degrees C. Fiber reinforcement was varied from 0 to 50 wt% at random orientation and mechanical, and water absorption properties were correlated with the glass fiber reinforced composite of the same weight percentage. The composite with a 40% fiber combination has an enhancement in mechanical, morphological, and thermal characterization. This comprehensive study confirms the usage of this bio-material in replacing harmful synthetic material in structural, marine and mechanical industrial applications.

Automated summary

The feasibility of using CFR fiber waste as a reinforcing material in a polyester-reinforced composite was investigated. The study found that CFR fiber has a high cellulose content, resulting in increased tensile strength and thermal stability. The mechanical and water absorption properties of the composite were correlated to the glass fiber reinforced composite. The composite with 40% fiber content showed enhanced mechanical, morphological, and thermal characteristics. This study confirms the potential usage of this bio-material in replacing harmful synthetic materials in structural, marine, and mechanical industrial applications.
