Mechanical properties of SEVA / hydroxyapatite composite with to HAP different particle sizes

Hydroxyapatite is a biocompatible ceramic and reinforcement for bone implantations. SEVA/HAP composite content HAP filler with difference particle sizes were designed. Mechanical tests like tensile modulus, UTS, strain at break and biodegradation were investigated. Results illustrated much increase tensile modulus of composites content HAP nano powders ratio to micro powders. Also UTS analysis of composites illustrated much increase UTS of composites content HAP nano powders ratio to micro powders and strain at break analysis of composites illustrated much decrease of strain at break composites content HAP nano powders ratio to micro powders. The composites degradation in PBS solution showed slowly degradation time of composites content HAP nano powders ratio to micro powders filler.
