Abstract

The invention discloses a composite bone plate of carbon fiber and polyether-ether-ketone and a preparation method thereof. The preparation method comprises the following steps: electrostatically spraying polyether-ether-ketone on each layer of carbon fiber cloth, overlapping the carbon fiber cloth in a mold layer by layer, closing the mold, performing mold pressing, cooling and opening the mold to take a product out, cleaning the product with a solvent, drying the product to obtain a block material, and performing CNC (Computer Numerical Control) machining on the block material according to a bone plate design drawing to obtain a bone plate blank; performing bio-safe coating treatment on the surface of the obtained bone plate. The bone plate has high biocompatibility; a biological coating is adopted, so that the biological security of medical implanting is enhanced; mechanical parameters are equivalent to those of a skeleton, so that the strength of the bone plate is closer to actual bone strength, the problem of adaption is solved, and the stress shielding effect caused by stress concentration is avoided; the bone plate has high X-ray penetrability, and is suitable for batch production.

Description

technical field

[0001] The invention relates to the field of orthopedic materials, in particular to a carbon fiber and polyether ether ketone composite bone plate and a preparation method thereof. Background technique

[0002] Traditional bone plate materials are stainless steel and titanium alloy; they have the following problems: 1. The mechanical properties, such as modulus, do not match with natural bone. If the gap is too large, it will cause stress shielding, bone resorption, bone inflammation, and then secondary surgery; 2. Long-term implantation, the dissolution of metal objects will cause cytotoxicity; 3. X-rays cannot penetrate, which affects the follow-up inspection of recovery after surgery; 4. Since it is a metal object, MRI detection cannot be performed after implantation.

[0003] PEEK (polyether ether ketone) plastic raw material is an aromatic crystalline thermoplastic polymer material with a melting point of 334°C. It has high mechanical strength, high temp...
