Introduction Nowadays, due to environmental pollution concerns and increasing of public awareness on environmental issue, bio-fillers is gradually replacing with an alternative renewable or 'eco-friendly material'.
The characteristic of new material that can be used to replace existing fillers must be environmentally friendly, inexpensive, light in weight and renewable [1].
In the context, microcrystalline cellulose (MCC) fulfil most requirements as filler due to its availability and abundance source, inexpensive and ‘green’ or naturally occurring material [6].
All materials were used as received.

In order to overcome the disadvantages of the native cellulose such as cotton, high degree of molecular crystallinity of about 70%, low molecular accessibility and low grafting yields, Tong Zheng et al. described the polymerization of super absorbent using cellulose in regenerated pulp as a raw material on which acrylic acid and sodium acrylate were grafted and its properties [5].

Introduction Epoxies are recognized as a high performance polymer materials and extensively used in the manufacture of high strength light body structure, especially in the aerospace and aircraft applications [1].
Although nanoparticles have good thermal and mechanical properties, nanoparticles filled polymer systems (called nanocomposites) have not yet met their full potential as advanced engineering materials.
The attractiveness of clay is due to its high ion exchange capacity, low cost, high aspect ratio and commonly developed which makes it workable to achieve a nanostructure from micron size filler as a starting material [2].

This objective may be attained if, during foundry practice, a hard layer of material is inserted in the regions where wear resistance is required.
Materials and Procedures In these experiments, ductile iron with the chemical composition indicated in table 1 was used as the base metal and a WC powder with 6 micrometer of average diameter was used as the main material to be inserted.
Evolution of VHN versus distance (d) to the external surface of the inserted layer (horizontal lines indicate the average hardness plus or minus twice the standard device for the unaffected material hardness).
