Embodiment 3

[0072] The glass composition is the same as in Example 2. The volume ratio of phosphate glass fiber to polylactic acid fiber in the blended yarn is 1:1.5. According to step 7, use a rapier loom to weave phosphate glass with a thickness of 0.32mm according to the plain weave process. Blended fabric with polylactic acid fiber. According to step 9, the composite material plate is manufactured, and the blended fabric is put into a mold after being laminated for hot pressing. The hot-pressing conditions are 180° C., 4 MPa, and the hot-pressing time is 20 minutes to make a composite board.

[0073] The composite material reinforced by glass fiber fabric (40% Vf, that is, the volume content of active phosphate-based continuous glass fiber is 25%), the initial bending strength and modulus are 280MPa and 14GPa, respectively. After 28 days of degradation in phosphate buffer (0.15Mol / LPH7.2), its bending strength can still maintain more than 50% of the initial strength.

Abstract

The invention discloses a biological reactive phosphate based continuous glass fiber textile composite and application thereof. The composite comprises biological reactive phosphate based continuous glass fiber fabric and biocompatible polymers or comprises blended fabric and biocompatible polymers, wherein the blended fabric is prepared from biological reactive phosphate based continuous glass fiber and polylactic acid fiber. The mechanical performance of the composite reaches the level of human bones, the mechanical property is matched with that of bone tissue, and meanwhile the composite has excellent biocompatibility, degradability and absorbability, can be compatible with natural bones and is good in processing performance.

Description

technical field [0001] The invention relates to a bioactive phosphate-based continuous glass fiber textile composite material and its application, belonging to the field of biomedical materials. Background technique [0002] There are three types of bone repair materials in clinical application: osteoinduction, osteoconduction and bone internal fixation. Osteoinductive materials directly induce mesenchymal cells to differentiate into osteoprogenitor cells and osteoblasts, and then form bone tissue, such as autologous bone and human teeth; osteoconductive materials provide scaffolds for the formation of blood vessels and the healing of broken bones. Such as tricalcium phosphate, hydroxyapatite, polylactic acid and other artificial polymer materials; metal and non-metal materials are used for bone fixation, and metal materials are more widely used, such as using metal bone plates to fix the bone directly inside or outside the broken bone. To connect or fix broken bones. Inte...
