Natural fiber composites are designed for different purposes including structural and non-structural ones. These natural fiber composites vary greatly in their properties including mechanical properties. Mechanical properties which include the tensile and flexural properties are highly dependent on factors such as matrix type, filler type, processing, post processing treatment and many more, factors which are quite application specific. However, many research works develop their natural fiber composite before considering the possible applications. This chapter intends to X-ray the factors that affect the mechanical properties as it relates to structural and biomedical applications and suggest ways of improving the mechanical properties.

The influences of surface treatment and the concentration of boehmite alumina (BA) particles on polypropylene and polystyrene (PS) (80/20) blends produced via melt compounding were examined. The results show that p‐toluene sulfonic acid‐treated BA particles yielded the highest stiffness improvement (27.5%), followed by untreated particles (25.7%), and dodecylbenzene sulfonic acid‐treated BA particles (8.5%). Transmission electron microscopy revealed that p‐toluene sulfonic acid‐treated BA particle agglomerates were dispersed in the PS phase, whereas untreated particles formed agglomerations at the interfaces. Dodecylbenzene sulfonic acid‐treated particles were poorly dispersed in both matrices. Differential scanning calorimetry showed that both untreated and p‐toluene sulfonic acid‐treated BA particles acted as nucleating agents in the blend because of the shifting of crystallization peaks to higher temperatures by 12 and 8 °C, respectively. A significant increase in decomposition temperatures occurred upon 7 wt % loading of all types of BA particles into the blend. Heat deflection temperature measurements showed that all types of BA particles improved the thermal properties of the blend. © 2018 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2018, 135, 46376.

The effect of graphite (G) and graphene oxide (GO) dispersions on the thermal, mechanical, rheological properties of biodegradable polylactide (PLA)/poly(E-caprolactone) (PCL) blend composites has been comparatively investigated. Surface morphology analysis indicates that the degree of morphological stability depends on not only the loading of the filler but also enthalpic interaction between the filler surface and the polymer blend. A significant improvement in the elongation at break (43.8%), with well-balance of modulus and strength characteristics, is observed for the G-filled (0.25 wt %) blend composite, whereas the GO-filled (0.05 wt %) ternary composite shows a strong (19 8C) improvement in the thermal stability. Furthermore, the dynamic modulus of the blends increased after composite formation; however, the degree of improvement is greater for the G-filled blend composites. On the basis of the obtained results, we propose a general description of how the morphology and structure of the blend composites are related to the final properties.
