The present invention relates to a method for manufacturing a carbon silicon sintered body having excellent tensile strength in a specific direction. Silicon carbide sintered bodies have low thermal expansion, high mechanical strength and thermal conductivity, and good oxidation resistance, so they are used as heat-resistant structural materials for heating elements, engine parts, and other parts.
Although this material has recently been used in a wide range of applications, it has the drawback of poor toughness compared to metals, and particularly low tensile strength. The present invention improves this and relates to a method for manufacturing a fiber-reinforced SiC sintered body that has extremely strong tensile strength in a specific direction.The present invention improves this and relates to a method for manufacturing a fiber-reinforced SiC sintered body that has extremely strong tensile strength in a specific direction. The fibers are arranged almost parallel to each other, and a carbon-containing binder is added to form the fibers, and then thermally decomposed in a non-oxidizing atmosphere to allow molten metal silicon to seep through, the entire structure is made up of SiC, W fibers, Si 3 N 4 and W fibers.
The present invention provides a method for producing a fiber-reinforced SiC sintered body, which is characterized by forming a composite of W fibers and Si 3 N 4 whiskers. Because it is blended in a specific direction, it has extremely strong tensile strength in the direction of fiber elongation, and because a small amount of metallic silicon remains, it has high toughness. Here, the Si 3 N 4 whisker is a whisker made of α-type or β-type silicon nitride. Next, to form this, W fibers and Si 3 N 4 whiskers are arranged on one plane in unspecified directions and bonded to obtain a thin plate that is strong against bending and tensile stress. Thin plates and impellers that are particularly resistant to stress, that is, centrifugal force, can be obtained, and if they are wound and bonded to the side of a cylindrical or rectangular object, even when a combustion reaction occurs internally, they will resist the stress and thermal strain of the gas caused by combustion. It is possible to obtain extremely strong cylinders and square tubes. In addition, if they are arranged parallel to a straight line and bonded together, a linear body that is particularly strong in that direction can be obtained, and if this is processed into a circular or coiled shape, it becomes suitable for rings, heat-resistant coil springs, etc. It has significantly greater toughness than a sintered body. Next, the carbon-containing binder must be adhesive and contain carbon, and pitch, tar, fatty acids, and especially thermoplastic or thermosetting resins can be effectively used. Resins containing silicon in addition to carbon are even better. These may be arranged while kneading with the W fibers and Si 3 N 4 whiskers, or after the W fibers and Si 3 N 4 whiskers are arranged, vibration may be applied to the liquid binder or it may be allowed to permeate. Even in the method described above, it is necessary to sufficiently fill the voids in the fibers, and if this is insufficient, the sintering will be insufficient accordingly, resulting in a decrease in strength. Further, after kneading, the W fibers and Si 3 N 4 can be arranged in a desired direction by rolling or extrusion. Next, in order to thermally decompose this and leave carbon behind, a non-oxidizing atmosphere, specifically an atmosphere of vacuum, hydrogen, argon, etc., may be used. The decomposed residual carbon at this time fills the gap between the W fibers and the Si 3 N 4 whiskers in the form of porous and highly active carbon, making it easier for molten metal silicon to permeate through capillary action, and fully reacting at around 1500℃. Causes sintering. This allows the reaction-sintered SiC bonded
Since a sintered body of Si 3 N 4 whiskers is obtained and a small amount of silicon remains, it has extremely high tensile strength and toughness in the fiber direction. The present invention will be explained in more detail below with reference to Examples, but the present invention is not limited thereto. Example 1 Commercially available W fibers with a diameter of 100μ and Si 3 N 4 whiskers (manufactured by Tateho Kagaku KK) were immersed in a mixture of isobutyl methacrylate, nitrocellulose, and dioctyl phthalate with a small amount of trichlorethylene added. The test piece was deposited in parallel by rolling it on a flat surface and forming a string, and then pressurized in a direction perpendicular to the axis to create a test piece with a thickness of 2 mm x width of 10 mm x length of 100 mm. After drying, it was heated to 800°C in an N 2 atmosphere.
was heated for 5 hours to thermally decompose the organic binder, and
An object was made by bonding fibers and Si 3 N 4 whiskers with carbon, then metal silicon powder and this test piece were placed in an alumina pod, and the temperature was raised to 1500°C in a vacuum to form metal silicon. It was melted and permeated into the sintered body, completing reaction sintering. this
Set it as No.1. Next, No. 2 was made in the same manner as No. 1 except that pitch was used instead of polyurethane resin. In addition, a test piece with the same shape as No. 1 was prepared using a conventional well-known reaction sintering method and designated as No. 3R. The characteristics of this are shown in Table 1. Table 1 shows that the fiber-reinforced SiC sintered body of the present invention had a longitudinal tensile strength that was more than 70% larger and a transverse rupture strength that was about 40% larger than that of conventional reaction-sintered SiC. This can expand the scope of its use as a heat-resistant structural material.

のである。[Table] Example 2 A commercially available W fiber with a diameter of 100μ and a Si 3 N 4 whisker were placed in parallel on one plane while repeating vibration and pressure.
Arranged in a thickness of mm and impregnated with tar mixed with carbon powder, pressed to form a flat plate with a thickness of 2 mm and a diameter of 60 mm.
After cutting into disks, reaction sintered SiC was prepared as No. 4 in the same manner as No. 2 in Example 1. Separately, a disk of the same shape was obtained using a conventional reaction sintering method, and this
The side view of No. 5R was installed on the top surface of the piston as shown in Figure 1. In the figure, 1 is an aluminum alloy piston, and 2 is a fiber-reinforced SiC sintered body. When this was installed in an internal combustion engine with a cylinder capacity of 1200 c.c. and operated for 100 hours, 4 out of 5 pieces of No. 5R were damaged.
In No. 4, none of the five pieces were damaged. Example 3 Commercially available W fibers and Si 3 N 4 whiskers were immersed in a molten pitch, rolled to a thickness of 3 mm while being wrapped around the side of a cylinder with a diameter of 100 mm, cooled, and made into a cylinder with an inner diameter of 100 mm.
A cylinder with an outer diameter of 106 mm and a length of 300 mm was molded. After this, reaction sintered SiC was prepared under the same conditions as in Example 2, and No.
Set it to 6. Next, a cylinder with the same shape was manufactured using the conventional well-known reaction sintering method, and it was named No. 7R. City gas is combusted inside this, and the internal temperature reaches 600℃ in 3 minutes.
No. 7R, which was tested at temperatures of 700℃, 800℃, and 900℃, broke at 600℃, while No. 6
was found to be extremely resistant to rapid heat without being destroyed even when heated to 950℃. Example 4 Commercially available W fibers with a diameter of 100μ and Si 3 N 4 whiskers were immersed in a molasses liquid, formed into a string with a diameter of 2 mm, kept semi-dry, and placed on the surface of a cylinder with a diameter of 50 mm in a pitch of 10 mm.
A coil spring having an axial length of 100 mm was obtained by winding the spring into a spiral shape, and it was made of reactive sintered SiC No. 8 in the same manner as in Example 2. In addition, a SiC coil spring with the same shape was manufactured using the conventional reaction sintering method and No.
No. 9 was compressed in the axial direction in a furnace at 1000°C and the amount of elastic deformation until fracture was investigated. No. 9R could be deformed by 5 mm, while No. 8 of the present invention could be deformed by 9 mm, making it difficult to use as a spring. We were able to greatly improve the utility value. As described above, the fiber-reinforced SiC sintered body according to the present invention has high tensile strength in a specific direction, is resistant to vibration shock, is resistant to thermal shock, and has large elastic deformation, and can provide a method for manufacturing heat-resistant parts that are strong and have great industrial utility value. It is something.
