向上には効果が少ない。 However, since it is inferior to metal materials in terms of wear resistance, there are limits to its application to fields where this type of performance is required. On the other hand, since the strength is inferior to metal materials,
There are also composites with carbon fiber (FRP),
Although such measures contribute to improving strength, they have little effect on improving wear resistance.

In addition, the entire or surface layer of the engineering resin molded body is covered by a ceramic composite layer in which engineering resin is impregnated into the pores of a ceramic porous body with a 70 to 90% void ratio in which the ceramic portion has a three-dimensional network skeleton. This is a configuration of the invention.

で構成されている。(Example) Fig. 1 shows a cylindrical ceramic composite resin molded body 1 according to a first embodiment of the present invention, in which engineering resin is impregnated into the voids of a cylindrical ceramic porous body 2' as shown in Fig. 2. The inner layer 3 is formed integrally with a resin of the same material as the resin impregnated on the inner surface of the composite layer 2.

れる。 Such a ceramic porous body is manufactured using foamed polyurethane and ceramic slurry. That is, a so-called polyurethane foam having a mesh-like skeleton is formed from polyurethane foam, and this is impregnated with a ceramic slurry, and the excess slurry is removed to obtain a structure in which ceramics are uniformly accumulated and adhered to the skeleton. Then, after drying and firing, a porous ceramic body in which the voids are completely communicated with the outside can be obtained. Moreover, according to such means, a porous body having a high porosity of 70 to 90% can be obtained.

が存し、本発明には適用し難い。 In addition, as a means to obtain a ceramic porous body,
There is a method of mixing a binder with ceramic particles, molding it into a desired shape, and then sintering the ceramic particles and causing the binder to disappear, but it is difficult to obtain a porous body with a high porosity, and There are independent voids in the pores, making it difficult to apply to the present invention.

体の強度が不足し、取り扱いが極めて困難とな
る。 The porosity of the ceramic porous body 2' is 70 to 90.
It is better to set it as %. When impregnating the voids of a porous body with a resin, since the resin has a high viscosity, if it is less than 70%, the impregnation may be insufficient, and if it is less than 70%, independent pores are likely to occur. On the other hand, if it exceeds 90%, the strength of the porous ceramic material before impregnation becomes insufficient, making handling extremely difficult.

常用いられる手段によればよい。 In order to impregnate the voids of the ceramic porous body 2' with an engineering resin such as an epoxy resin depending on the application, a method commonly used in the field of resin molding such as high-pressure injection molding may be used.

効果的に付与されるている。 Here, an enlarged schematic diagram of the ceramic composite layer 2 in which the ceramic porous body 2' is impregnated with resin is shown in the third figure.
As shown in the figure. Ceramics part 2a is resin base material 2b
Moreover, the resin base material 2b is in a continuous state in the ceramic composite layer 2, and the resin base material 3b firmly holds the ceramic portion 2a of the three-dimensional network skeleton. Therefore, the strong motion of the resin does not decrease much. Therefore, the ceramic composite layer 2 retains both properties, and the abrasion resistance of the ceramics is effectively imparted to the properties of the resin.

ことができる。(Effects of the Invention) As explained above, the ceramic composite resin molded article of the present invention has a ceramic composite layer with a void ratio of 70 to 90%, in which the voids are interconnected and the ceramic portion has a three-dimensional network skeleton. Since the voids of the ceramic porous body are impregnated with engineering resin, there is no part that is not impregnated with resin.
The ceramic portion is firmly held by the surrounding resin, and the properties of both ceramics and engineering resin can be evenly combined throughout the composite layer.
