Abstract—The mechanical behavior of carbon-filled plastic plates and plates made of carbon-filled plastic–titanium nickelide hybrids imitating spring elements of dynamic ankle foot orthoses (DAFO) has been investigated. It has been found that according to the stacking scheme and number of carbon fabrics layers, the elasticity modulus varies from 12.4 to 97.0 GPa and the proportionality limit changes from 115 to 703 MPa. Hybrids of two types have been considered: (i) a structure consisting of screwed nickelide titanium and carbon-filled plastic plates and (ii) a hybrid composite with a carbon-filled plastic matrix reinforced with 2.2 × 2.2-mm titanium nickelide rods. It has been shown that both the hybrid structure and carbon-filled plastic–titanium nickelide hybrid composite are promising for DAFO production. These materials combine good elastic, strength, and damping properties with a lesser number of carbon fabrics layers (from three to five) than in the case of nonreinforced carbon-filled plastic.

弯曲应变碳填充塑料和碳填充塑料-镍钛杂化复合材料的力学行为

摘要研究了动态踝足矫形器（DAFO）中碳填充塑料板和碳填充塑料-钛镍化物混合材料板的力学行为。研究发现，根据不同的堆叠方式和层数，碳纤维织物的弹性模量在12.4 ~ 97.0 GPa之间变化，比例极限在115 ~ 703 MPa之间变化。已经考虑了两种类型的混合材料：(i)由螺纹镍化钛和碳填充塑料板组成的结构；（ii）由2.2 × 2.2 mm钛镍化棒增强的碳填充塑料基体的混合复合材料。结果表明，杂化结构和碳填充塑料-镍钛杂化复合材料都是生产DAFO的理想材料。这些材料结合了良好的弹性、强度和阻尼性能，与非增强碳填充塑料相比，碳织物层数较少（从3到5层）。

期刊介绍： Russian Metallurgy (Metally) publishes results of original experimental and theoretical research in the form of reviews and regular articles devoted to topical problems of metallurgy, physical metallurgy, and treatment of ferrous, nonferrous, rare, and other metals and alloys, intermetallic compounds, and metallic composite materials. The journal focuses on physicochemical properties of metallurgical materials (ores, slags, matters, and melts of metals and alloys); physicochemical processes (thermodynamics and kinetics of pyrometallurgical, hydrometallurgical, electrochemical, and other processes); theoretical metallurgy; metal forming; thermoplastic and thermochemical treatment; computation and experimental determination of phase diagrams and thermokinetic diagrams; mechanisms and kinetics of phase transitions in metallic materials; relations between the chemical composition, phase and structural states of materials and their physicochemical and service properties; interaction between metallic materials and external media; and effects of radiation on these materials.
