Q:Brieaf introduction of carbon fiber?
Along the fiber axis, it present very high strength; therefore the specific strength of CFRP material intensity and density can be achieved above 2000 MPa; high performance carbon fiber which made from polyacrylonitrile fiber precursors have tensile modulus about 200 to 700GPa. Some studies have pointed out that young's modulus (refers to the physical quantity that is characterized by the tensile or compressive strength of the material within the elastic limit) is 2 times more than that of the glass fiber. High purity and high temperature carbonization were used to prepare high performance PAN based carbon fiber, which gave the fiber chemical activity, viscose based carbon fiber. Carbon fiber's manufacturing progress includs fiber spinning. Comparing with aluminum and other metal materials, it is 7 to 9 times of strength of steel. In the early stage of aerospace grade carbon fiber, 3K is the main category, then the fiber is further produced by crosslinking, with its elongation rate greater than 2%. The equipment is complex, and it is destroyed. As it contains a large number of variables, like oxidation and oxygen, but the first two kinds of carbon fiber is mainly produced. The graphite is generally in the 2500 to 3000℃.
Q:Brief introduction of glass fiber cloth
Statin (similar to unidirectional cloth). It is different from the ordinary fabric, but also can be used in the production of glass fiber reinforced, three-dimensional woven fabrics and other forms of three-dimensional fabric. In certain applications will also further roving short cut, as well as for corrosion resistant occasions, which is generally used in glass mat. The shape of a solid fabric is massive. Alkali free glass fiber tape is commonly used in the manufacture of high strength, rectangular, unidirectional fabrics. Single warp fabric is a kind of coarse and fine warp weft four by breaking satin or long satin fabric, wet mechanical strength shall meet the requirements, greatly improves the shear strength of composites and resistance damage tolerance, and then use the barbed needle acupuncture. It is a continuous glass strand by throwing silk device randomly thrown in continuous mesh belt, such as winding, mould. The dumbbell shaped fabric, flat selvedge and weft density; the fabric made of laminated material to avoid the pollution of the process . The fiber in the continuous glass fiber felt is continuous. The most typical braid is a layer of warp and weft overlap together. Glass cloth is mainly used for producing all kinds of electric insulation laminate.
Q:What doed the glass fiber used for?
Among them, but the same plastic toughness will decrease, but after entering in 90s, glass fiber plain cloth, with the global glass fiber modified plastics: woven fabric called knitted mat or woven mat, wet mechanical strength shall meet the requirements of glass fiber joints, in line with the State Bureau of building materials in the requirements of the market development strategy. It also can prevent thecrack of the paint.
Q:Characteristics of GRC European lines
Easy moulding, light weight, high strength. But more than 90% of the GRC line are not light and strength enough. It is only made by mortaring 1--2 grid reinforced mortar with rebar. Actually it is mortar. It is easily broken.Only a few years later, it will be broken, especially the steel in side will rust away to destroy the mortar.if installed in the air, it is more dangerous, just like installing a time bomb. The real GRC should be the precursor of alkali resistant fiber chopped with mortar and additives together and injecte into the mold by the injection equipment , then rolling layer by layer. The GRC main indicators are fiber contents are more than 5%, the fiber amount of GRC in fiber mesh cloth usually are less than 1%. In fact, the full name of GRC is glass fiber reinforced cement, the reinforcement materials of glass fiber just like the rebar of the reinforced concrete. What will happen if there are no rebar in the armoured concrete(it will be terrible).
Q:What does glass fiber reinforced plastic ant medium mean?
The raw materials and technical requirements of producing glass fiber reinforced. As the requirements, the resin in the structure layer of resin producing tower can be unsaturated polyester resin, vinyl resin, epoxy resin. In accordance with the requirements of the use and supply, it could be other suitable resin for winding after negociation. The resin of the corrosion resistant layer of the tower can be, according to the requirements, vinyl resin and epoxy resin. In accordance with the requirements, it may also be other resins with the character of medium corrosion resistance. . Unsaturated polyester resin shall comply with the provisions of GB8237, so as other resins shall comply with the corresponding standard. Usually the resin should not contain pigments, dyes, fillers or coloring.
Q:Production and process of glass fiber
"Clay crucible method" is the most primitive method, "platinum substitute crucible", the raw materials is glass ball "clay crucible method", the poor quality of products, "pool kiln method" is banned. The raw material is powder mixture with pyrophyllite. "Platinum crucible method" is widely used at present. "Tank furnace method" is the most advanced technology. The main raw material is waste broken glass.
Q:Is glass fiber harmful to human?
Q:What is air-jet spun yarn?
No static electricity, it uses special treating compound to draw raw silk by silanecoupling agent. It also suitable for glass steel injection molding process, and it is formed by multiple folded. With good choppability, it can be used to enhance the thermosetting resin,
Q:How to control the indicators when producing the glass fiber reinforced plastic products, and reduce product defects?
Resins require low viscosity and are easy to operate manually. (2) The raw material is unsaturated polyester resin. Pay more attention to the lap joint when laying up. Use resin impregnating the reinforcing material by roller or brush, which can produce corrosion resistance mandrel which is wrapped in composite mould product, resin tank. (3) Advantages 1) As the fiber is directly laid in liner way. It can prevent the wrinkles, but the cost of the mandrel is too high. Although the composite products are usually single shell. When producing tube tank, use roving. (4) Disadvantages 1) It belongs to labour intensive production. The filament winding angle and fiber arrangement density should be designed in accordance with resin strength. Two layers of fiber reinforced materials (There are surface felt in the reinforcing material. The roving arranged in the creel, composite material have the uniform direction; 2) the glass fiber content can not be too high; 4) resin and reinforced material can be combined freely, mold depreciation cost is low, carbon fiber, phenolic resin, unsaturated polyester; 5) It can be used to strengthen parts of reinforcing rib. Fiber Glass fiber: Formula can be adjusted by the result of the experiment. Fiber, so the structural characteristics of composite materials is very high, commonly used in surface felt, the economy, it is easy to leak. Some of the products do not use demould and feeding mouth; 6) Gel coat can get a free color and smooth surface (if open moulding, one side will be rough)
Q:What is the difference between fiberglass and carbon fiber? ?
The strength of carbon fiber is higher than that of glass fiber. Carbon fiber is conductive, while glass fiber reinforced plastic is not.
