    • The present invention relates to an organic-inorganic composite including ceramic particles having micro protrusions formed on surfaces. The micro protrusions that are formed on the surfaces of the ceramic particles increase a resin binding force and have an anchoring effect for slip suppression. Accordingly, a shearing resistance force between the ceramic particles and a resin interface and a shearing resistance force between the ceramic particles and the ceramic particles are significantly enhanced and high mechanical strength characteristics can be obtained to resist various types of damages such as brittle fracture, ductile fracture, and fatigue fracture. The present invention is configured to contain multiple anisotropic ceramic particles with different aspect ratios; and a resin that is bonded to the ceramic particles. The multiple protrusions that are formed to protrude from the surfaces of the ceramic particles are further provided so that the shearing resistance force between the ceramic particles and the resin interface is enhanced. Also, at least some of the adjacent ceramic particles are adjacently arranged for partial inter-protrusion contact. Accordingly, the shearing resistance force between the ceramic particles themselves can be enhanced by the protrusions which are in contact with each other.
    • 本发明涉及一种有机 - 无机复合材料,其包括在表面上形成微小突起的陶瓷颗粒。 形成在陶瓷颗粒表面上的微小突起增加了树脂的结合力,并具有滑动抑制的锚固效果。 因此,陶瓷颗粒与树脂界面之间的剪切阻力和陶瓷颗粒与陶瓷颗粒之间的剪切阻力显着增强,并且可以获得高机械强度特性以抵抗各种类型的损伤,例如脆性断裂,延性 骨折和疲劳骨折。 本发明被配置为包含具有不同纵横比的多个各向异性陶瓷颗粒; 和与陶瓷颗粒结合的树脂。 形成为从陶瓷颗粒的表面突出的多个突起进一步设置成使得陶瓷颗粒和树脂界面之间的抗剪切力增强。 此外,相邻陶瓷颗粒中的至少一些相邻地布置用于部分突起间接触。 因此,可以通过彼此接触的突起来增强陶瓷颗粒本身之间的抗剪切力。
