Abstract

The invention discloses a carbon fiber composite material bone plate and a preparation method thereof. The preparation method specifically comprises the following steps of: coiling, stacking and laying up carbon fiber prepreg cloth according to the design, preheating, pre-forming, preheating and molding; cooling, feeding into a demolding table, opening the mold, taking out the product, cleaning and drying; performing CNC machining on a bulk material according to a bone plate design drawing so as to form a bone plate blank; and performing biosafety coating treatment on the surface of the obtained bone plate blank. The bone plate is high in biocompatibility; by virtue of biological coating, the biosafety of medical implants is improved; the bone plate is close to real bone strength; the various mechanical parameters are equivalent to those of bones, the adaptation problem is solved, and a stress-shielding effect caused by stress concentration is avoided; the carbon fiber composite material bone plate has excellent X-ray penetrability, can meet the nuclear magnetic resonance testing requirements and is suitable for batch production and low in cost.

Description

technical field

[0001] The invention relates to the field of orthopedic materials, in particular to a carbon fiber 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 will cause metal dissolution and cytotoxicity; 3. X-rays cannot penetrate, which will affect the follow-up inspection of postoperative recovery; 4. Since it is a metal object, MRI detection cannot be performed after implantation .

[0003] CF (carbon fiber) is a high-strength, high-modulus fiber material with a carbon content of more than 95%. It is a microcrystalline graphite material obtained by stacking organic fibers such as flake graphite microc...
