Cellulose fibers, cell wall fragments and cellulose microfibrils can be used as reinforced materials for biocomposite manufacture. Understanding nano-mechanical properties of those materials will be very useful to show their full theoretical potential. Nanoindentation testing is a technique that determines the mechanical properties of a material in the sub-micron/nano scale. The test involves p...

Fibers are one of the most prevalent methods to enhance tensile capacity concrete. Most researchers focus on steel fiber reinforced concrete which is costly and easily corroded. This study aims examine performance polypropylene through different tests. PPFs were added into blends in a percentage 1.0%, 2.0%, 3.0%, 4.0% by weight cement offset its objectionable brittle nature improve capacity. Th...
