A comparative study of the structure and properties of composite materials produced from biogenic hydroxyapatite/glass/carbon fibers, depending on the type of carbon fibers (activated carbon nanostructured fibers or cellulose fibers), was conducted employing scanning electron microscopy, X-ray diffraction, infrared spectroscopy, Brunauer–Emmett–Teller method, helium pycnometry, and in vitro experiments. The potential to produce a biogenic hydroxyapatite/glass/carbon fiber composite by sintering at 800°C, involving the simultaneous formation of carbon nanostructures during thermal destruction and carbonization of cellulose fibers, was ascertained. This method allows preserving the hydroxyapatite phase in the newly formed biogenic hydroxyapatite/glass/carbon fiber composite and ensures the presence of carbon nanostructures. The microstructure of the composites produced with activated carbon nanostructured fibers is characterized by the presence of these fibers, contrastingly to the composite produced with cellulose fibers, which has more homogeneous microstructure. Moreover, as opposed to cellulose fibers, activated carbon nanostructured fibers in the composite significantly increase (by more than three times) the specific surface area of the material and significantly reduce the particle size. Regardless of the carbon fibers used, the biogenic hydroxyapatite/glass/carbon fiber composites are nanostructured and microporous (pores < 2 nm). The resorption rate of the biogenic hydroxyapatite/glass/carbon (activated nanostructured or hydrated cellulose) fiber composites in the physiological solution within the first two days is significantly higher than that of the starting biogenic hydroxyapatite/glass composites because of changes in the porous structure.

根据碳纤维的类型（活性炭纳米结构纤维或纤维素纤维），采用扫描电子显微镜、X射线衍射、红外光谱法、Brunauer-Emmett-Teller 法、氦比重法和体外实验。确定了通过在 800°C 下烧结生产生物羟基磷灰石/玻璃/碳纤维复合材料的潜力，涉及在纤维素纤维的热破坏和碳化过程中同时形成碳纳米结构。该方法允许在新形成的生物羟基磷灰石/玻璃/碳纤维复合材料中保留羟基磷灰石相，并确保碳纳米结构的存在。用活性炭纳米结构纤维生产的复合材料的微观结构的特征在于这些纤维的存在，与用纤维素纤维生产的复合材料相比，后者具有更均匀的微观结构。此外，与纤维素纤维相反，复合材料中的活性炭纳米结构纤维显着增加（三倍以上）材料的比表面积，并显着减小颗粒尺寸。无论使用何种碳纤维，生物羟基磷灰石/玻璃/碳纤维复合材料都是纳米结构和微孔的（孔径< 2 nm）。由于多孔结构的变化，生物羟基磷灰石/玻璃/碳（活化纳米结构或水合纤维素）纤维复合材料在生理溶液中的前两天内的吸收率明显高于起始生物羟基磷灰石/玻璃复合材料。
