Characterization of New PEEK/HA Composites with 3D HA Network Fabricated by Extrusion Freeforming.

Addition of bioactive materials such as calcium phosphates or Bioglass, and incorporation of porosity into polyetheretherketone (PEEK) has been identified as an effective approach to improve bone-implant interfaces and osseointegration of PEEK-based devices. In this paper, a novel production technique based on the extrusion freeforming method is proposed that yields a bioactive PEEK/hydroxyapat...

Properties of Polypropylene Composites Fabricated Using Twin-screw Extrusion

Sunflower hull sanding dust (SHSD) filled polypropylene (PP) composite was prepared using a twin-screw extruder. Mechanical and thermal properties of the SHSD/PP composite were characterized contrasting to organically modified clay /PP composite. Differential scanning calorimetry (DSC) analysis showed that the crystallization temperature and the degree of crystallinity of PP exhibited changes w...

A novel bioactive PEEK/HA composite with controlled 3D interconnected HA network

Polyetheretherketone (PEEK) is a high-performance thermoplastic biomaterial which is currently used in a variety of biomedical orthopaedic applications. It has comparable tensile and compressive strength to cortical bone with favourable biocompatibility. However, natural grade PEEK-OPTIMA has shown insufficient bioactivity and limited bone integration. Bioactive PEEK composites (e.g., PEEK/calc...

AZ31/HA-Zeolite Nano Crystalline Biocomposite Fabricated by Mechanical Alloying and Powder Metallurgy: Mechanical Properties

  Magnesium and its alloys are light, biodegradable, biocompatible metals that have promising applications as biomaterials. Magnesium is potentially useful for orthopedic and cardiovascular applications. However, the corrosion rate of this metal is so high that its degradation occurs before the end of the healing process. One of the ways to improve the corrosion rate is to compose it’s with cer...
