ABSTRACT: This paper reviews the machinability and mechanical properties of natural fiber-reinforced composites. Coupling agents, operating parameters, as
well as chemical treatment effects on natural fiber-reinforced composites’
machinability are also reviewed. Moreover, the impacts of fibers’ physical
properties on the machinability of the composite are mentioned. Fiber volume
fraction (Vf), fiber orientation as well as chemical treatment
effects on mechanical properties are also defined. Conclusively, the
effect of fibers’ physical properties as
well as mechanical properties is described. It was discovered that chemical treatment of natural fibers improved their compatibility with the
matrix by removing their surface tissues, increasing the roughness average (Ra), and reducing moisture
absorption. Also, the Orientation of the fiber plays an important role in controlling the mechanical
properties of the composite. Moreover, some physical properties of the
fibers, including quality of fiber distributed
in the matrix; fiber size, length, and diameter; moisture absorption;
porosity and the way fibers break during compounding with the matrix, were
found to affect the mechanical properties of the composites formed.
