What are the commonly used fiber reinforced materials, fiber reinforced resins used for?

1. Fiberglass.

Glass fiber reinforcement is currently the most widely used material reinforcement method. According to the chemical composition, glass fiber can be divided into alkali-free aluminosilicate (referred to as alkali-free fiber) and alkali-free borosilicate (referred to as alkali-free fiber). As a reinforcing material, glass fiber has the following advantages:

Hard but impermeable, will not rot and mildew, resistant to heat and chemical corrosion, has high tensile strength and ideal elasticity as well as excellent electrical properties. Glass fiber can be used to reinforce thermoplastics such as PP, PET, PA, PC, etc., and is also widely used in thermosetting plastics.

Glass fiber reinforced plastics have the advantages of high specific strength, corrosion resistance, heat insulation, dielectric, and easy molding. The tensile strength of glass fiber reinforced thermosetting plastics can reach 100MPa, which is similar to that of general steel, and the surface relative density is only 1 4 of steel. Glass fiber reinforced PP polypropylene has been widely used in auto parts, home appliance industry, aircraft manufacturing industry, etc.

The interface bond between glass fiber and matrix polypropylene has a great influence on the mechanical properties of composite materials, and it is generally treated with coupling agent or grafted polypropylene to increase capacity.

Polyceron glass fiber reinforced material: glass fiber reinforced PC series.

Features: low floating fiber, good chemical resistance, high fuel injection yield, good rigidity and toughness balance, etc.

Applications: mobile phone frames, printers, cameras, learning machines, etc.

Typical grades: P1110, P1120

Second, carbon fiber.

Carbon fiber is made by carbonizing polyacrylonitrile fibers, viscose or bitumen precursors. Due to different raw materials and manufacturing methods, the strength and modulus of carbon fiber are also different. The relative density of carbon fiber is, while the relative density of glass fiber is about that; The tensile strength, flexural strength and modulus of carbon fiber reinforced composites are significantly higher than those of glass fiber reinforced composites.

The coefficient of thermal expansion of carbon fiber is low, and the shrinkage of carbon fiber composite material is 1 2 of glass fiber reinforced material and 1 5 of unreinforced resin. Carbon fiber reinforced composite material is a new type of composite material with light weight and high strength, which is not only widely used in the aviation and aerospace industries, but also has been applied in sports and daily necessities. Carbon fiber also has the characteristics of high temperature resistance and electrical conductivity, which can be used for electrostatic spraying and preparation of antistatic parts.

Carbon fiber can be used in thermoplastics such as PC, PC ABS, PA, PP, PE, etc., as well as thermoset plastics such as epoxy resins.

Due to its high quality, carbon fiber is currently mainly used in automobiles, aircraft and military fields. With the improvement and reduction of carbon fiber manufacturing process, carbon fiber composite materials will be used in all industrial sectors, including machine building, household appliances, packaging containers and equipment, daily necessities, etc.

Polyceron carbon fiber reinforced material: carbon fiber modified products.

Features: High fluidity, surface resistivity 10 1012cm

Application: OA products, industrial wear-resistant products, electronic appliances, mobile phones, notebook shells, etc.

Typical grades: PA6 2133, PA6 2513, PA62922, PC ABS 2123, PC ABS2513

The first concept of fiber reinforced materials is to explain the concept of "composite materials". Broadly speaking, a composite material refers to a material that is composed of two or more components (units) with different properties or different organizations. From an engineering point of view, composite materials refer to new materials made by artificially combining two or more materials with different properties but complementary properties.

The composition of the composite material is divided into two parts: the matrix and the reinforcement. The continuously distributed components are usually called matrices, such as polymer (resin) matrix, metal matrix, and ceramic matrix; Substances that disperse fibers, particles, whiskers, etc., in the matrix are called reinforcements.

In the 21st century, the development and application of advanced composite materials (ACM) will enter a period of rapid development, so the development of composite reinforcements is very important. All components that play a role in improving strength and performance in polymer matrix composites can be called reinforcing materials. The varieties of new fibrous reinforcing materials for composite materials based on epoxy resin are:

Glass fiber, carbon fiber, ultra-high relative molecular weight polyethylene fiber, polyaramid (aramid) fiber, PBO fiber, boron fiber, etc.

Fiber-reinforced thermoplastic pellets are granular mixtures made of fiber-reinforced materials and thermoplastic resins. According to the fiber length in the pellet, it is divided into: long fiber reinforced pellet, which is produced by the coating method, and the fiber length is about 5mm; Short fiber reinforced pellets, produced by screw extrusion, long fibers.

The fiber is commonly used glass fiber, and carbon fiber can also be buried; The resins are polypropylene, polyvinyl chloride, polyethylene, polystyrene, nylon, polycarbonate, chlorinated polyether, etc. It is mainly used for the extrusion method to produce linear products such as pipes, rods, plates and foreign liquid profiles, and can also be used to produce mechanical parts, building hardware, sanitary and lighting equipment, air conditioner blades, etc.

Synthetic resin is widely used in the separation and purification of impurities in liquids in industrial production, including macroporous adsorption resins, ion exchange resins, and some resins.

Resin usually refers to an organic polymer that has a softening or melting range after being heated, and has a tendency to flow under the action of external force when softening and letting go, and is solid, semi-solid, and sometimes liquid at room temperature. The relative molecular weight is uncertain but usually high, and at room temperature it is solid, medium-solid, pseudo-solid, and sometimes it can also be a liquid organic substance. It has a softening or wide melting temperature range, has a tendency to flow under the action of external force, and often rupture in the shape of a shell.

Broadly speaking, it refers to polymers or prepolymers that are used as plastic substrates. Generally insoluble water, soluble in organic solvents. According to **, it can be divided into natural resin and synthetic resin; According to the characteristics of its different processing behaviors, it is divided into thermoplastic resin and thermosetting resin.

Fiber-reinforced resin matrix composites are first widely used in the aerospace field due to their small specific gravity and high mechanical and chemical properties, including mechanical materials such as gears and bearings for artificial stools and satellites and high-performance aircraft, as well as lightweight materials such as wings and aircraft bodies.

What is the use of glass fiber resin for brightening and strengthening? AS plastic is made of glass fiber reinforced AS plastic, which can increase the strength and thermal deformation resistance, reduce the coefficient of thermal expansion, and is widely used in the fields of auto parts, air conditioning, electronic entertainment, sports and entertainment equipment.

AS plastic is made of glass fiber reinforced AS plastic, which can increase the slip reduction strength and thermal deformation resistance, reduce the thermal expansion coefficient, and is widely used in the fields of auto parts, air conditioning, electronics, sports and entertainment equipment.

Fiber-reinforced composites can be divided into short-fiber reinforced composites, long-fiber composites and messy short-fiber reinforced composites by the length of the fibers. There are many varieties of fiber reinforced composite materials due to the movement and slip of side wax fibers and substrates, such as carbon fiber reinforced epoxy, boron fiber reinforced epoxy, kevlar fiber reinforced epoxy, kevlar fiber reinforced rubber, glass fiber reinforced plastic, boron fiber reinforced aluminum, graphite fiber reinforced aluminum, carbon fiber reinforced ceramics, carbon fiber shielded strong carbon and glass fiber reinforced cement.

20.What is the method by which the nano reinforcements of metal matrix nanocomposites are added to the matrix alloy?

Metal matrix composites refer to new materials made by adding inorganic non-metal (or metal) reinforcements of different sizes and forms (including fibers, whiskers, particles, nanoparticles, etc.) to the metal matrix by artificial methods.

What are the spiritual reinforcement materials fiberglass factory, I don't do this business, I don't know much about it, you can ask these majors.

The principle of glass fiber reinforcement:

The connection between the glass fiber and the resin interface must make the force acting on the molded pants be transmitted to the glass fiber, so the length of the glass fiber is fully utilized to play the purpose of resin reinforcement.

Factors influencing the strength of glass fibers:

1.Fiber diameter and length: the smaller the diameter, the smaller the length, the greater the strength;

Chemical composition: alkaline content (sodium oxide.

Potassium oxide. The larger it is, the smaller the strength, the worse the chemical stability and electrical insulation properties, except for hydrofluoric acid.

In addition to HF), concentrated alkali (NaOH) and concentrated phosphoric acid, it has good chemical stability to all chemicals and organic solvents.

Carbon fiber reinforced composites are composite materials formed by carbon fiber or carbon fiber fabric as reinforcement and resin, ceramic, metal, cement side combustion, carbon or rubber as the matrix. It has high specific strength and specific rigidity in many lightweight materials, and the lightweight effect is very obvious, and the megacavity is widely used in aerospace and military products. It is used in the body structure parts, and the effect of reducing the mass is particularly obvious, which is 50% lighter than steel materials and 30% lighter than aluminum, so it has received extensive attention from major automobile companies outside the domestic industry.
