Abstract
In recent years the biocomposites are highly utilized in the biomedical applications, due to excellent strength as well as weight ratio. A lot of natural fibers, namely, flax, hemp, jute, kenaf, and sisal are cheaply available in colossal amount. Aim of this study, a novel approach, is executed for construction of biomedical orthopedic parts by using mixture of natural fibers. This work handled biocomposites such as flax fiber (FX), chicken feather fiber (CF), kenaf fiber (KF), and rice husk fiber (RH) effectively. From all these composites, four sets of mixed fibers with reinforcement of polylactic acid polymer used for creating orthopedic parts. The hand-lay-based methodology is undertaken for preparation of hybrid biocomposites. Parameters involved for this study are fiber types (KF + RH, RH + FX, FX + CF, and CF + KF), laminate count (2, 4, 6 and 8) infill density (30%, 60%, 90%, and 120%), and raster angle (0/60, 30/120, 50/140, and 70/160). Finding of this work is dimensional accuracy, flexural strength, and shore hardness that are analyzed by L16 orthogonal array. ANOVA statistical analysis is enhanced and enlightens the results of flexural strength and source hardness of the biocomposites. Amongst in four parameters, the fiber type parameter extremely contributes such as 40.50% in the flexural analysis. Similarly, laminate count parameter highly contributes such as 31.01% in the shore hardness analysis.
Highlights
In recent trends, the biomedical applications are fulfilled by the composite material especially biocomposites
Maximum flexural strength was obtained as 24.89 MPa by influencing of combination of chicken feather fiber and kenaf fiber, laminate count of 6, infill density of 60%, and raster angle of 70/160
Biomedical applications such as orthopedic parts were produced by using of biocomposites, namely, flax fiber, chicken feather fiber, kenaf fiber, and rice husk fiber
Summary
The biomedical applications are fulfilled by the composite material especially biocomposites. The natural fibers are produced the biocomposites with reinforcement of polymer. Natural fibers possess low weight and high strength; it has used in the industrial applications in medical appliances. It has best suited for preparation of composites due to no environmental affects for humans. Few of the biocomposites applications are tissue engineering, orthopedics, dental post, bone plate, composite pins, screws, and clips in spinal fusion. The study of chemical treatment to the natural fibers is vital role in composite preparation. Morphological study of the electrospun and thermal analysis is major role in the tissue engineering [2].
