Investigating the effects of carbon and glass fiber on increasing the Bending strength of artificial Stone and studying their structure using SEM

Artificial stone is a mixture of natural aggregate and additives such as industrial gums (resin), cement and other polymer materials. In this research artificial stones with different additives and resins were designed to achieve high flexural capacity with mixing design, 84% aggregate, 10% resin and 6% additive completely manually without vacuum and pressure system. FESEM images were taken from specimens to determine fine cracks, elements, manufacturing atoms, weight percentages, and how to add and interconnect the additives used in making artificial rocks. To determine the ductility and evaluation of the quality of artificial rocks by their ability to withstand cracks or other surface roughness over a continuous bending period, artificial rocks made with additives (glass fiber, carbon fiber, polyester resin And vinyl ester) Three-point bending test Based on the three-point bending test, the sample made from wilin ester resin and the carbon fiber, had the most flexural strength and a sample made from wilin ester resin and the glass fiber tolerated the most strain during bending. Also, the type of fracture and cracks in the reinforced rocks are brittle and flexural respectively, and are ductile and shear-bending in rocks without reinforcing.
