When we fabricate a NFRPC by PP as base matrix and Wheat straw as natural fiber; using Injection moulding process, what effects are there on mechanical properties of the base material?
Hello Abhishek Dwivedi , first a question: are you injecting only the PP Matrix material or do you use short fibers within the injection molding process?
Assuming you extract the fine bast fibers from the wheat and the tensile strength of these fibers is (significantly) higher than that of the matrix, you will probably achieve a higher tensile strength and stiffness in fiber direction, depending also on the fiber volume content (the strain will determine failure in fiber direction). You will see anisotropic material behavior if the fibers will be aligned and the strength across fiber direction is significantly lower than in fiber direction, but possibly still somewhat higher than for the pure Matrix. You surely will produce a material with good damping effects and low density. Better shrinkage behavior than for PP-GF Composites. Also for non-directed short fibers you will see sdome of the Advantages.
In which form ( short fiber or powder) will be reinforced in PP matrix? If you are using short fibers you need to check for Tensile, Bending and Impact Strength..
