Principal advantages of composite materials resides in the possibility of obtaining new structural properties. Reinforcement opened the way to the polymers that are the last dominant materials in the engineering fields. As a matter of fact the modern development of polymeric materials and high modules fillers introduced new generation of composite materials irrespective of cost. The proposed polymeric composite will be formed with base of polyurethane and unsaturated polyester. The used chemical mixed with different fly ash percentages are prepared in molds, after the composites solidify samples are ready to check by impact test machine (either Izod or charpy test) for calculating the impact energy.Keywords

Castor oil plant (Ricinus Communis) is growing in many places in the world, its seeds contain between 40% and 60% oil, the extract process are not toxic. The slow burning oil is used mostly to fuel lamps, lighting, body ointments, and improving hair grown and texture, in local medicine as laxative, purgative and cathartic also for curing arthritic. Castor oil is the only oil in nature which having hydroxyl groups in backbone. It is chemically modified to obtain oil based polyols by mixing different fly ash percentages with them for preparation high rigid structural polyurethane (PU) with it. The generated polyols (castor oil + different fly ash percentages (10%, 15%, 20%, 25%, 30%) are being checked to get viscosities at different fly ash percentages.Keywords
