【摘要】 研究了碳纤维四步法三维四向、三维五向编织复合材料的拉伸、压缩和弯曲性能,研究了表面编织角的变化对其拉伸、压缩和弯曲性能的影响,并与层合复合材料和用于接骨板的金属材料作了对比性研究。结果表明:三维编织复合材料具有良好的力学性能,编织角和编织结构对复合材料性能有较大的影响。随着编织角的增大,复合材料的拉伸、弯曲强度和模量均减小。通过对编织角的设计,就可以改进三维编织复合材料的性能,体现了此材料在制作接骨板方面的优越性。更多还原

【Abstract】 The tensile,compress and bending properties of 4-step three-dimensional four-direction and five-direction braiding composites were studied.The influence of braiding-angle on their mechanical properties were also discussed.And the mechanical properties of three-dimension braiding composites were compared with that of laminated composites and metal for bone-plate usage. The results show that:1) 3-D braiding composites have better mechanical properties than laminated composites.2) The braiding-angle has a great influence on their mechanical properties.The strength and modulus would decrease with the braiding angles increasing.3) The mechanical properties of 3-D braiding composites can be determined by designing their braiding structure.So 3-D braiding composites are suitable for bone-plate usage.更多还原
