1. The characteristics are different.

Fiberglass. The advantages are good insulation, strong heat resistance, good corrosion resistance, and high mechanical strength, but the disadvantages are brittleness and poor wear resistance.

Carbon fiber. Carbon fiber has many excellent properties, carbon fiber has high axial strength and modulus, low density, high specific performance, no creep, ultra-high temperature resistance in non-oxidizing environment, good fatigue resistance, specific heat.

and conductivity between non-metals and metals, coefficient of thermal expansion.

Small and anisotropic, good corrosion resistance, X-ray.

Good permeability. Good electrical and thermal conductivity, good electromagnetic shielding, etc.

2. The definitions are different.

Glass fiber: Glass fiber is an inorganic non-metallic material with excellent properties.

Carbon fiber: Carbon fiber is a new type of fiber material with high strength and high modulus fiber content of more than 95%.

3. Different uses.

Fiberglass: Twistless roving is made from bundles of parallel precursors or parallel monofilaments. Checkered cloth is a non-twisted roving plain weave fabric, which is an important substrate for hand lay-up FRP. Fiberglass felt, ground fiber, fiberglass fabric, combined fiberglass.

Carbon fiber: Carbon fiber carbon materials have been widely used in various fields of military and civilian industries. From aerospace, aviation, automobile, electronics, machinery, chemical, textile and other civil industries to sports equipment and leisure products.

The chemical composition is completely different, glass fiber is characterized by cheap, physical properties are average, carbon fiber is high, but the physical properties such as tensile strength are very good, and the biggest point is light weight.

Compared with carbon fiber: low modulus, high elongation at break, cheap, but weighty, poor workability, and concrete may have alkaline reaction (this point still needs to be further studied) purely from a technical point of view, the effect of glass fiber reinforced concrete columns is better, and the effect of carbon fiber for bending reinforcement is better.

Glass fiber** is lower and the strength is lower, but what is the comparison of the comprehensive performance of the two?

How? I think each has its own strengths.

What is the difference between the construction process of the two? Which is more reliable?

From the point of view of construction technology, carbon fiber is easy to infiltrate, good.

What is the status of research on both fronts? What is the status of the application?

There are many related researches, and in terms of application, there are more carbon fibers, mainly because of high profits.

Which of the two is more promising?

I think each has its own strengths, and it should be used reasonably and comprehensively.

However, there is a certain difference between the two in terms of structural force, and it must not be calculated by generation.

The material is different. Glass fiber is an inorganic non-metallic material with excellent properties. It is glass balls or waste glass as raw materials that go through high-melting, drawing, winding, weaving and other processes to finally form glass fibers.

Carbon fibers are inorganic fibers made up of the element carbon. The carbon content of the fiber is greater than 90%. Generally, it is divided into three categories: ordinary type, high-strength type and high-model type.

The main difference between glass fiber and carbon fiber is that the chemical composition is completely different, and glass fiber is characterized by cheap and low physical stability, but carbon fiber is high, but high physical stability, and the biggest feature is light weight.

Glass fiber (glass fiber or fiberglass) is an inorganic non-metallic material with excellent performance, with a wide range of advantages, such as good insulation, strong heat resistance, good corrosion resistance, and high mechanical strength, but the disadvantage is brittleness and poor wear resistance. Its main components are silica, alumina, calcium oxide, boron oxide, magnesium oxide, sodium oxide, etc., according to the alkali content in the glass, it can be divided into alkali-free glass fiber, medium alkali glass fiber and high alkali glass fiber. Glass fiber is commonly used as a reinforcing material in composite materials, electrical insulating materials and thermal insulation materials, circuit substrates and other fields of the national economy.

According to the shape and length, glass fiber can be divided into continuous fiber, fixed-length fiber and glass wool; According to the composition of glass, it can be divided into alkali-free, chemical-resistant, high-alkali, medium-alkali, high-strength, high elastic modulus and alkali-resistant (alkali-resistant) glass fiber.

Carbon fiber is a new type of fiber material with high strength and high modulus fiber content of more than 95%. It is a microcrystalline graphite material made of organic fibers such as flake graphite microcrystalline stacked along the axial direction of the fiber, and obtained by carbonization and graphitization treatment. Carbon fiber is "soft on the outside and rigid on the inside", the weight is lighter than that of aluminum, but the strength is higher than that of steel, and it has the characteristics of corrosion resistance and high modulus, which is an important material in the national defense and military industry and civilian use.

It not only has the intrinsic properties of carbon materials, but also has the soft processability of textile fibers, and is a new generation of reinforced fibers.

Both are inorganic non-metallic materials. Glass fiber melts glass materials (quartz sand, alumina and pyrophyllite, limestone, dolomite, boric acid, soda ash, miscanthus salt, fluorite, etc.) at high temperature, and then draws, winds, and weaves into glass fiber cloth, and then according to the design of the product, it is shaped into the final appearance. The diameter of a single fiber is usually a few microns to more than 20 microns.

Glass fiber has excellent insulation, high temperature resistance and corrosion resistance, and has a low level.

Carbon fiber is made of carbonized fiber made of graphite pressing, with a carbon content of more than 90%, and it also goes through processes such as wire drawing and winding weaving, and finally uses molds to wrap the carbon fiber cloth layer by layer into the appearance of the finished product, and cures it with epoxy resin. Compared to glass fiber, carbon fiber materials generally have higher properties, and compared to glass fibers, carbon fibers have more than 3 times the Young's modulus (the physical quantity of solid materials that resist deformation), and have stronger corrosion resistance and lower weight.

1. The material is different.

Glass fiber is an inorganic non-metallic material with excellent properties. It is glass balls or waste companion glass as raw materials through high-melting, wire drawing, winding, weaving and other processes, and finally forming glass fibers.

Carbon fibers are inorganic fibers made up of the element carbon. The carbon content of the fiber is greater than 90%. Generally, it is divided into three categories: ordinary type, high-strength type and high-model type.

2. The characteristics are different.

High tensile strength of glass fiber; High elasticity coefficient; High impact strength; chemical resistance; Low water absorption; Good heat resistance; There are many types of processed products; Transparent colloid.

Carbon fiber is a new type of material with higher strength than steel, less density than aluminum, more corrosion resistance than stainless steel, high temperature resistance than heat-resistant steel, conductivity like copper, and electrical, thermal and mechanical properties. Compared with glass fiber (GF), Young's modulus is more than 3 times that of it, and it is insoluble or swollen in organic solvents, acids and alkalis, and has outstanding corrosion resistance.

3. Different uses.

Glass fiber is mainly used to make reinforced plastics, and the reinforced plastics made of glass fiber make glass fiber far more widely used than carbon fiber.

Carbon fiber is mainly used in high-end fields, and can be used as aircraft structural materials, electromagnetic shielding and de-energizing materials, artificial ligaments and other body substitute materials, as well as in the manufacture of rocket shells, motor boats, industrial robots, automotive leaf springs and drive shafts. Carbon fiber is widely used in civil, military, construction, chemical, industrial, aerospace and supercar fields.

Carbon fiber is better, and the performance of carbon fiber will be better than that of glass fiber. Composite parts are generally close to the performance of reinforcements, and the use of carbon fiber is mostly involved in epoxy resin composite or vacuuming, and the natural performance is not bad. Fiberglass parts are the most common, and the economic advantage is relatively obvious.

Therefore, good or bad should be judged from the point of no more guessing.

Which is a good pro, glass fiber composite material or carbon fiber! Hello, I'm glad to answer for you<> the pro-comparison is good for carbon fiber. Glass fiber is an inorganic non-metallic material with excellent properties.

It is made of pyrophyllite, quartz sand, limestone, dolomite, boronite, and boronite as raw materials through high-temperature melting, wire drawing, winding, weaving and other processes. The advantages are good insulation, strong heat resistance, good corrosion resistance, and high mechanical strength, but the disadvantages are brittleness and poor wear resistance. Carbon fiber is a high-strength and high-modulus fiber with a carbon content of more than 90%.

High temperature resistance ranks first among all chemical fibers. It is made of acrylic fiber and viscose fiber, which is oxidized and carbonized at high temperature. It is an excellent material for the manufacture of aerospace and other high-tech equipment.

Hope mine can help you <>

Do you have any other questions?

Summary. The main difference between them is actually not big, but because the production makes about seventy-five materials have different properties, so they have some differences in the formula. The silica content of ordinary glass is generally less than 60 percent, while the content of glass fiber is generally less than 60 percent.

Fiberglass cloth is a very fine glass filament, which is made of glass after drawing, after drawing, the glass filament has a strong thermal softness and elasticity. Then you can use a loom to make fiberglass cloth. However, the heat resistance of glass filament is not as good as that of glass cloth, and it is easier to melt because the surface area of the glass filament is too large.

Glass is an inorganic material, after more than eight high temperature melting, when below the temperature of the softening point, there will be no chemical change, when above the softening point, long will only soften, dissolve and other phenomena, will not burn, so the danger is low.

In any case, glass will not burn, sometimes the burning phenomenon we see is a process of improving the performance of fiber cloth, glass cloth can be used to make fireproof clothing, fire clothing and other products, but do not directly contact**, broken glass fiber will sting**, and make people feel itchy.
