Metallurgical and shear strength of brazed bulk pure copper by microwave hybrid heating

The Compressive Strength of Unsaturated polyester reinforced by natural and synthetic Calcium Carbonate

“…Table (1) and table (2) shows the values of forces applied on samples and the change in theirs thick ,where the change in thick increase by increases in the values of applied compressive forces, these results are agreed with [8].…”

“…By growing need of the society of constructions, materials with high quality and low cost, Composite materials have been used, the material such as ceramics, metals and polymers play the role of a matrix phase in composite, while fibers or particles acts as reinforcement phase to obtain the composite optimum features [1].In Polymer matrix composites with fibers, the advantages of use of fibers is that it can reduce the cost of composites and helps in improving mechanical properties , the fibers size, quantity and quality were effect on the final properties of composites [2]. The presence of nano scale fibers give nano composites a new properties that are not present in original composites [3] .…”
