Abstract:
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.

The present invention relates to an organic-inorganic composite containing ceramic particles with micro projections on surface wherein the micro projections formed on the surface of ceramic particles increase a coupling property, shows an anchoring effect suppressing a slipping phenomenon and shear resistance between ceramic particles is greatly enhanced to ensure excellent mechanical strength property to resist various types of damages such as brittle fracture, ductile fracture and fatigue failure. The present invention is composed of a plurality of anisotropic ceramic particles with different aspect ratios and a resin combined with ceramic particles, and a plurality of projections on the surface of the ceramic particles increase shear resistance between ceramic particles and the resin. Parts of adjacent ceramic particles are closely arranged such that projections partly contact one another to increase shear resistance between ceramic particles.
