| Abstract | ||
| In this research it has been calculating the impact strength on polyester composites reinforced by rock wool fibers with two kinds (smooth and rough)، the results have been shown that when strengthening the resins material by fibers and carrying out the same testing conditions that the fracture energy for polyester specimens as a matrix less than the fracture energy for composite rock wool. It is also noticed that the impact strength depends on the structural properties of the fibers where the impact strength can be increased when the weight is increasing of two kinds of the rock wool fiber. | ||
