聚醚醚酮（Polyether Ether Ketone , PEEK）材料因其具有出色的机械性能、热稳定性和耐腐蚀性而被广泛应用于医疗器械领域。当PEEK材料作为医疗植入物应用于髋关节置换等场景时，受到了较高的静态压载和较强的动态冲击载荷，这些载荷都会影响植入物的稳定性和可靠性，因此，对PEEK材料进行静动力学性能研究是十分有必要的。本论文针对PEEK材料作为植入物因静动态载荷引起损伤和失效等问题，研究了纤维增强和结构设计与优化提高PEEK材料静动力学性能的关键技术，为实现PEEK材料复合和PEEK点阵材料结构设计、优化与制备提供理论与方法依据。

本论文以PEEK材料为研究对象，添加短切碳纤维（Carbon Fiber , CF）、玻璃纤维（Glass Fiber , GF）作为增强材料，系统地研究了增强纤维对PEEK实心材料的静动力学性能影响规律，并探究了其失效机理；基于仿生思想设计了以“仿竹胞元”为基础的均质、三维点阵结构和夹芯板，并采用熔融沉积制造技术（Fused Deposition Modeling, FDM）制备了PEEK三维点阵结构和夹芯板，研究了胞元结构、功能梯度两因素对PEEK三维点阵结构的准静态压缩力学性能的耦合影响，探究了胞元结构、胞元几何参数对PEEK夹芯板的低速动态冲击力学性能的影响规律，获得了PEEK多孔材料胞元结构仿生设计及胞元几何参数优化的方法。具体研究内容如下：

采用FDM技术制备了PEEK、碳纤维增强聚醚醚酮（Carbon Fiber Reinforced Polyether Ether Ketone, CF-PEEK）和玻璃纤维增强聚醚醚酮（Glass Fiber Reinforced Polyether Ether Ketone, GF-PEEK）拉伸和三点弯曲试样，通过拉伸和三点弯曲实验研究了纤维增强对PEEK材料的静力学性能的影响规律。作为纤维增强材料，CF短切纤维较GF短切纤维能更好提高PEEK复合材料的抗拉和抗弯曲性能，CF-PEEK复合材料弹性模量较纯PEEK材料明显提升。

PEEK is widely used in the field of medical devices due to its excellent mechanical properties, thermal stability, and corrosion resistance. When PEEK is used as medical implants in scenarios such as hip joint replacement, it is subjected to high static pressure loads and strong dynamic impact loads. These loads can affect the stability and reliability of the implants. Therefore, it is essential to study the static and dynamic properties of PEEK. This dissertation focuses on the issues of damage and failure of PEEK as implants caused by static and dynamic loads. It investigates the key technologies of fiber reinforcement and structural design and optimization to enhance the static and dynamic properties of PEEK. The research provides a theoretical and methodological basis for the compounding of PEEK materials and the design, optimization, and preparation of PEEK lattice structures.

To address the above issues, this dissertation focuses on PEEK materials, adds short chopped carbon fibers, glass fibers as reinforcing materials, systematically studies the influence of reinforcing fibers on the static and dynamic mechanical properties of solid PEEK materials, and investigates their failure mechanisms. Based on bionic principles, a homogeneous, three-dimensional lattice structure and sandwich panel based on "bamboo cell element" were designed. PEEK three-dimensional lattice structures and sandwich panels were fabricated using Fused Deposition Modeling (FDM). The coupling effects of cell structure, functional gradient factors on the quasi-static compression mechanical properties of PEEK three-dimensional lattice structure, and the impact of cell structure, cell geometric parameters on the low-speed dynamic impact mechanical properties of PEEK sandwich panels were studied. The study obtained a method for bionic design of PEEK porous material cell structure and optimization of cell geometric parameters. The specific research contents are as follows:

Fused Deposition Modeling (FDM) technology was employed to fabricate tensile and three-point bending specimens of PEEK, Carbon Fiber Reinforced Polyether Ether Ketone (CF-PEEK), and Glass Fiber Reinforced Polyether Ether Ketone (GF-PEEK). The influence of fiber reinforcement on the static mechanical properties of PEEK materials was studied through tensile and three-point bending experiments. As a fiber-reinforced material, short carbon fiber could better enhance the tensile and flexural properties of PEEK composites compared to short glass fiber, and the elastic modulus of CF-PEEK composites was significantly improved over pure PEEK material.

(2) Solid plates of PEEK, CF-PEEK, and GF-PEEK were prepared, and the dynamic performance of PEEK and its fiber-reinforced PEEK under different impact energies was studied through low-velocity dynamic impact tests. A Johnson-Cook finite element model based on Hashin failure criteria was established, and the low-velocity dynamic impact process of solid plates was numerically simulated to verify the effectiveness of the finite element model. Using this model, the low-velocity dynamic impact processes of PEEK composites with different fiber contents were simulated, obtaining the influence pattern of fiber reinforcement on the dynamic performance of PEEK solid materials. short chopped fibers of CF and GF could effectively improve the dynamic performance of PEEK materials, and the higher the fiber content, the more pronounced the improvement in the dynamic performance of PEEK composites.

(3) Taking bamboo as a biological model, a bionic design of bamboo-like cellular structures was conducted. Based on the bionic and traditional geometric cellular structures, homogeneous and functionally graded three-dimensional lattice structures were designed. PEEK three-dimensional lattice materials were fabricated, and the coupled effects of functionally graded materials and cellular structures on the quasi-static compressive mechanical properties of PEEK lattice porous materials were investigated experimentally and numerically. Functionally graded materials exhibited a clear advantage over traditional homogeneous materials in terms of energy absorption, with the compressive modulus and specific energy absorption per unit volume of functionally graded materials being superior to those of homogeneous materials. Cellular structures also significantly influenced compressive strength and energy absorption characteristics, with the bamboo-like cellular structure showing the best performance among the three structures.

(4) Based on the bionic designed bamboo-like cellular structure, a core board structure was obtained through a two-dimensional array of cellular elements, and upper and lower panels were added to design a bamboo-like cellular sandwich plate. A cube and honeycomb cellular sandwich plate were also introduced for comparative analysis. Three PEEK sandwich plate materials with different cellular structures were prepared, and their dynamic performance under low-velocity dynamic impact was studied through experiments. It was found that different cellular structures exhibited significant differences in low-velocity dynamic impact resistance, with the bamboo-like cellular sandwich plate performing the best. Using Computed Tomography (CT) non-destructive testing technology, the internal damage of failed specimens was observed, and the transition of failure modes from ductile to brittle failure with increasing impact velocity (energy) was investigated.

(5) Focusing on the honeycomb cellular PEEK sandwich plate, a finite element model of the honeycomb cellular PEEK sandwich plate was established. Experimental and numerical simulation results under 15J impact energy were compared and analyzed to verify the effectiveness of the finite element model. The Taguchi experimental method was introduced to design 9 groups of experimental models, and dynamic performance indicators such as peak load and Specific Energy Absorption (SEA) were obtained through numerical simulation. Using Minitab software, the main factors affecting the dynamic performance of the PEEK sandwich plate were analyzed in terms of cellular geometric parameters. It was clarified that a honeycomb cellular PEEK sandwich plate with larger column diameters, smaller hexagonal outer diameters, and higher cellular heights would exhibit superior impact resistance.
