Polypropylene fibers are added to concrete improve the toughness of material. Manufactured sand and fly ash with high content used reduce impact on environment cost. The response surface method (RSM) was design test study mechanical bending properties polypropylene-fiber-reinforced high-performance (PPFHPC). Three process variables, including polypropylene fiber (1%, 1.5%, 2%), (45%, 60%, 75%),...

This manuscript describes the rapid surface modification of carbon fibers using small molecules for application in polypropylene composites at 10% and 40% weight fractions. Attachment an n-butylphenyl species onto fiber incorporation into homo-polypropylene resulted a significant toughness improvement, 32% 30% fractions respectively, when compared against untreated control samples. Further exam...

Reactive Powder Concrete (RPC) is a combined material that will allow the concrete industry to enhance consumption, produce economic benefits, be more durable, and environmentally friendly. Due highly dense microstructure of RPC, it performs poorly at high temperatures due formation pore pressure, which causes breakdown. This paper demonstrates outcomes an investigational study behavior six RPC...

Lightweight composites are preferred for automotive applications due to the weight restrictions and also due to the presence of inherent voids that can enhance the sound absorption of these composites. The density of the reinforcing materials plays a crucial role in such lightweight composites. Milkweed is a unique natural cellulose fiber that has a completely hollow center and low density (0.9...
