Background: Plastination is a technique of long-term preservation of the natural tissues without the typical problems related to wet specimens. Plastinated specimens are durable, dry, and flexible. In this process, the water and fat in biological tissues are substituted by a curable polymeric resin, i.e., subsequently cured. In this study, a new unsaturated polyester resin (P96) was synthesized...

This research includes the preparation of polymeric composites by (Hand lay-up method) unsaturated polyester resin as a matrix material and (iron, copper) particles strengthening materials with different weight ratios (5%, 10%, 15%, 20%). The hardness impact strength properties are studied before after immersion in (NaOH) solution (HCl) at normality (0.3N) for period one (30 days). results show...
