Mechanical Properties and Morphological Studies on Pu-Ha Biocomposite
Khalid Mohammed Dahham | Mohamed Ansari M. Nainar
Abstract: This work demonstrates mechanical properties and morphological of polymer Polyurethane and bio composite hydroxyapatite (PU/HA), it was used four types of experiment, the mechanical properties (tensile test, flexural test, impact test and the SEM). The samples were with the different filler loading (2, 4, 6, 8, 10 wt %) and with dimensions 15 x 13 x 3 mm were used. These are used in many biomedical and applications because if their bioactivity and because their mechanical properties can be adjusted to suit. Hydroxyapatite, with biocompatibility and bioactivity, has already been used in clinics for filling of bone defects due to its similar chemical composition and structure to the mineral phase of human bone, and it can form bone bonding with living tissue. Polyurethane is one of the most versatile polymers for many different applications because of its good biocompatibility and favorable mechanical properties. Polyurethanes are used extensively in the medical field as intravascular devices, ureteral stents, for meniscal reconstruction, cartilage and bone repair. These polymers have excellent mechanical properties; high elongation capacity, good abrasion resistance, high flexibility and hardness, and good biocompatibility. These polymers coating can improve the biocompatibility of by blocking the diffusion of poisonous elements from the metal into the body. For that, the purpose from this article it will be the focus of improvement of the properties of PU-HA by using experiment, study and develop better to mechanical properties, by using several testing ways.
