Whether Natural fibers be reinforced with Metal matrix to improve their properties? What kind of mechanism is involved in this?
I don't think it can be an option. Fibers will degrade at 180-200 degress and also, there will be a poor interface even if acheived.
In my opinion, it has less advantage. People appreciate carbon fibre not because of the strength but the excellent (small) density. Most of metals are strong and heavy; there is no advantage of such "fibre reinforced metal". Moreover, metals usually have excellent elongation; the fibre also need to have very good elongation. Natural fibers usually have better elongation than carbon, but not as metals. If possible, light metals as Al or Mg alloys with fibre may be good candidates. These alloys are usually brittle and light. The reinforcement with fibre may provide additional toughness and fatigue property. What do you think?
Thank you Professor Fukada for your valuable guidance and suggestion
thermal stability of natural fibers does not allow to reinforce metallic matrix.
It is a possible professor, In that case, you can make natural fiber and metal power or ceramic particle with Epoxy resin.
It is not possible to reinforce natural fibers in metal matrix composites.They are not compatible (physical and chemical properties) with a metallic matrix to provide strengthening. Further, the temperature during processing would destroy the natural fiber.
Sir you can try to bind them in powder form with the help of epoxy resin, Hand lay up process or compression moulding can be tried. Additive manufacturing can also give better result but for metal manufacturing, it is still in develepment stage i guess.
Dear sir,
It is possible to bind them in powder form with the help of epoxy / polypropylene resin, Hand lay up process or VARTM method can be used.
It is impossible to reinforce natural fibers in Metal matrix.. but you can use metals or alloys or ceramics as a fillers in Natural fiber composites..
Please kindly go through this.

Dear Senthil,
Off course it is possible and there are plenty of research which has been done earlier. By binding them in powder form(only powder metallurgy route is possible- Since they are not compatible (physical and chemical properties are different) with a metallic matrix to provide strengthening(so simple route is not good to go with). Further, the temperature also a factor, which during processing would destroy the length and dimension of natural fiber provided this brings up to particulate matter size or short orientation size(mixing/fusing is always a problem) and hand lay process can be used for composite manufacturing. Strength, stiffness, absorption and impact is another issue with metal using natural fiber.
Jute is a common reinforcement in India . Natural fibers are increasingly used in automotive and packaging materials. Thousands of tons of different crops are produced but most of their wastes do not have any useful utilization. Agricultural wastes include wheat husk, rice husk, and their straw, hemp fiber and shells of various dry fruits. These agricultural wastes can be used to prepare fiber reinforced polymer composites for commercial use.
Hope it help you out.
