Filler materials useful in the present invention include abrasion resistant ceramic filler materials and abrasion resistant Contains metal filler materials.

An important aspect of the invention is a giratant that facilitates shaping the mixture into arbitrary shapes. The creation of a unique polymer/filler material mixture.

Specifically, by selecting specific combinations of filler materials and polymers, , it is possible to flow a material mixture into molds with complex shapes using relatively weak vibrations. Ru.

After the glaitant mixture has secured the shape of the mold, the polymer matrix is cured. In this way, a relatively rigid self-supporting polymer matrix composite is formed. , which can then be removed from the mold.

DETAILED DESCRIPTION OF THE INVENTION AND PREFERRED EMBODIMENTS In the present invention, there are many methods for producing self-supporting polymer matrix composites. A number of materials are disclosed for use in the method. Specifically, various polymers and When used in combination with various filler materials, a desirable wear-resistant self-supporting porous material can be achieved. can result in a reamer matrix complex.

In a first preferred embodiment of the invention, a suitable filler material is selected. Phila – Materials are characterized by their composition, abrasion resistance of the filler, and loading of the filler in the polymer. be able to obtain a particle size distribution that is consistent with the shape of the individual filler particles, be able to bind to the polymer matrix, during processing and in the resulting product. selection based on several different criteria, including synergy between the filler and the polymeric material. be done. Furthermore, suitable The selection of a suitable polymeric material also depends on several different criteria, e.g. The filler material should be able to provide lubricity to the filler material, thereby Wetting of filler material particles with polymer and mixing of polymer and filler under vibration Allows them to flow together relatively easily during molding of objects. Polymer is poly The viscosity should be low enough to allow the mer and filler to be mixed together. the viscosity and rheological behavior of the polymer under the process conditions of the present invention. and filler material mixture to allow flow. at least partially of the filler material Allows filling to occur and removes all closures within the polymer matrix during processing. The polymer may not solidify or solidify prematurely to allow trapped gases to degas or release. should not cure (eg, have a sufficiently long pot life).

Also, the polymer should have relatively little shrinkage involved during curing and The remer should be able to work and cure at room temperature or relatively low heating, and the polymer is itself abrasion and tear resistant.

Filler materials useful in the present invention include ceramic filler materials, such as carbides (e.g., carbon silicon oxide particles, tungsten carbide particles), oxides (e.g. alumina particles), nitrides (e.g., aluminum nitride particles), borides (e.g., titanium diboride), etc. Carbide is preferred.

Note that under the processing conditions of the present invention, a self-supporting polymer matrix with desired properties can be produced. No need to pre-treat or pre-coat ceramic filler material to obtain a composite There isn't. Abrasion resistant metal particles can also be used in the present invention.

Coarse-sized silicon carbide particles have been found to be a particularly desirable filler material. Ru. Most silicon carbide particles are relatively inexpensive, readily available, and wear resistant. silicon carbide in some specific way, requiring pretreatment or coating. It is known to bind to many of the desired polymers used in the present invention. Special A suitable filler is a coarse mixture of silicon carbide particles. Coarse silicon carbide size The jagged surface provides a good bond between the silicon carbide and the polymer. It is thought that it will be useful for Highly desirable anti-abrasion properties can be achieved with suitable polymer matrices. Approximately 10 parts by weight of 14-grid and 4 parts by weight of 54-grid in an appropriate amount of is known to be obtained by forming a mixture of The above weight ratio is for efficiency. provides a good filling and also allows bonding between the silicon carbide and the polymer to occur. . It also has an average particle size of about 700-8000 mm present in an amount of about 50-100% by weight. Chron particles are present in an amount of about 0 to 50% by weight and have an average particle size of about 150 to 700 mm. Desirable filling and desirable abrasion resistance also for blends of aggregates mixed with Kron particles Provide wearout results.

fillers so as to provide synergistic effects that can be obtained using the technology of the present invention. It is important to choose the appropriate combination of material mixtures and polymers, e.g. Because it is desirable to include certain filler materials as reinforcement for certain polymers, If so, the mixture of filler material and polymer should result in all the above advantages. be. Also, the specific combination of filler material and polymer matrix Upon shaping, you should end up with a giratant mixture. Here, dilatant is , the polymer-filler mixture exhibits shear thickening during mixing before curing, but This means that it has good fluidity under mild vibrations. Therefore , after the mixture of polymer and filler is charged into a specific mold by some suitable technique. , the mild vibrations of the mold cause the mixture to flow into even the most intricate details of the mold. Also, typically , the filler remains substantially uniformly distributed throughout the polymer matrix densely packed into the reamer matrix.

Particularly useful polymeric matrix materials have a diameter of about 100 to 400 centivoids, more preferably Preferably, it is an abrasion resistant polymer having a viscosity of about 150 to 250 centivoise. It was discovered that When mixed with silicon carbide particles, such polymers can provide anti-friction properties to mixtures of mer and silicon carbide, thus making silicon carbide particles Wet the particles completely with the polymer and allow each to flow relatively easily. Also, about Certain polymeric materials with a viscosity of 200 centivoise are polymers and filler materials. Thick concrete when completely mixed without inhibiting mixing of ingredients It has been found that it has a consistency comparable to that of however When this mixture is charged into a vibrating mold, the polymer and filler material flow and move inside the mold. Efficient and virtually uniform filler material within the polymer that attempts to match the side dimensions The aim is to allow a filling to occur. In addition, low viscosity polymers are Facilitates evacuating or releasing trapped air from Trix. It has been discovered. Numerous polymer materials with the properties listed above, plus those that can be processed at about room temperature. fees are available.

It has been found that the appropriate ratio of filler material to polymer is an important aspect of the invention. There is. 20-80% by weight of polymer to about 70-80% by weight of silicon carbide filler material A particularly preferred ratio of 30% by weight shows very desirable properties and also filler materials. The weight ratio may vary depending on the relative density of the polymer and the polymer. Here, as above It is important that the mixture of filler material and polymer is giratant; Thus, for example, a suitable volume percent of filler in a polymer matrix composite is approximately It varies from 70 to 80% by weight. In a preferred embodiment, silicon carbide particles in the above ratio (i.e., about 10 parts by weight of 14 grits to about 4 parts by weight of 54 grid days) When 80% by weight is mixed with about 20 parts by weight of polymeric material, the result is as above. is a giratant mixture.

After thoroughly mixing the silicon carbide particles and the polymeric material by any suitable means, the obtained Pour the mixture into molds.

The mold should not adversely affect the processing or the properties of the resulting Polymer/Linox composite. It can be made from any material and in any shape. A particularly suitable mold material is silicone rubber. be. Specifically, silicone rubber is used in all polymer matrix composite materials. It does not interact adversely with quality and can be molded into virtually any shape. Also, The silicone rubber mold cures the polymer and forms a polymer matrix composite. Provides flexibility for easy removal after formation.

Also, in most cases the amount of polymer provided to the matrix should be as low as possible. (e.g., sufficient space between matrix and filler material) (just enough to provide a bond).

Providing a small amount of polymer compared to filler improves the abrasion properties of composites The amount of filler material present can be maximized and thus improve the wear properties of the composite material. Potentially improve. Additionally, polymers are more effective than most filler materials used in this invention. They also tend to be more costly and are therefore less expensive than polymers that do not contain any fillers. Therefore, increasing the filler volume fraction may reduce the cost of the composite.

The frequency and amplitude of the vibrations applied to the mixture in the mold are important aspects of the invention. It has been discovered. If the vibration is too weak, the mixture will flow and conform to the internal dimensions of the mold. If the vibration is too strong and the filler material is not properly filled, air bubbles may form. Cannot be removed from the mixture.

Preferably, the bond between the filler material and the polymer is stronger than the polymer itself; Thereby minimizing loss of filler material during wear applications. This bond is It can be a combination of both chemical and mechanical factors. Specifically, fi The surface chemistry of the filler material improves the chemical bond between the filler and the matrix material. Sometimes. In addition, the surface morphology of the filler is due to the physical relationship between the filler and the polymer. For example, filler particles may improve bonding with respect to physical bonding. The more regular the shape, the better the physical bond between the matrix and filler. It has been found that Furthermore, the shape of the filler particles is determined by the shape of the filler particles under the processing conditions of the present invention. In combination with Rimmer, only a small amount of filler is required for MARIX. It should be chosen such that sedimentation will occur. This small amount of sedimentation is caused by the vibration of the present invention. A substantially heterogeneous self-supporting polymer matrix composite that typically results during the process It may end up in the body.

As mentioned above, the frequency and amplitude of vibration of a mold containing a mixture of polymer and filler are The mixture of polymer and filler should be selected so that it flows and conforms to the shape of the mold. In a preferred embodiment of the invention, the filler to the polymer matrix is - The amount of sedimentation of the material wets the surface of the filler material and when cured the polymer matrix To provide just the amount of polymer necessary to bind the filler material in the mix. Make it more minimal. ? j [Once the mixture of gold materials assumes the shape of the mold, immediately Preferably, the mixture is cured by curing of the polyester, as described above. Curing of the mer occurs before the mixture has had enough time to flow into the mold. It shouldn't be allowed.

After the polymer has cured, it can be removed from the mold and becomes a self-supporting polymer. - The matrix composite should then match the shape of the mold.

By following the above processing process, silicon carbide having a density of about 2.28 g/cc is obtained. It has been found that self-reinforced, self-supporting matrix composites can be formed; The composite material is about 56% filler by volume or about 79% filler by weight. Carbonization The ion particles are completely uniformly filled throughout the polymer matrix.

In addition, the ratio of filler material to polymer described above and the use of relatively low viscosity polymers are also important. By using this method, the M of the filler material increases when vibration is applied to the mold. This unique method of the present invention has been found to have surprisingly low The self-supporting polymer matrix composite formed by the present invention There are few restrictions on the shape or size of the polymer. Only one side of the plate has a high filler concentration due to settling of the filler material in the matrix. If such settling occurs, one of the plates side has significantly different wear characteristics than the other side of the plate.

Therefore, in the present invention, due to lack of filler separation, any number of We can also manufacture parts with irregular shapes, and this shape has the ability to manufacture complex mold shapes. limited to only. Since the filler is distributed substantially throughout the part, wear of the part is reduced. The properties are substantially constant throughout. A person skilled in the art will know how to produce using the method of the present invention. A large number of wear parts can be quickly appreciated.

Note that the ratio of polymer and filler is adjusted so that at least some desorption of the filler occurs. It is possible to change. In certain cases, non-uniform self-supporting polymer matrices It may be desirable to produce a complex.

Various illustrations of the invention are set forth in the following examples, which are considered by way of illustration only. and should not be construed as limiting the scope of the invention to the scope of the claims. do not have.
