Effect of Cellulosic and Rockwool Fibres on Mechanical strengths and Ballistic Impact of Epoxy-bentonite NanoComposite

Nowadays, research studies about optimal application of natural resources in products manufacturing instead of fossil and non-renewable resources are of utmost and ever growing importance. Cellulosic resources as the future reliance of Green products and also mineral mines as plenty, cheap and avail...
