- 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.

- According to the orders of reinforced material combination,the fabric surface is sill-like: Along the width of the direction of the area, the quality is uniform,twistless roving is chopped and sprayed in the net with the certain shape and distributed in the resin paste; the smooth surface make the surface of the glass steel smooth. Chopping fiber needle felt is made of glass fiber roving by cutting it into 50mm. Various performance requirements and winding roving winding are roughly the same; Continuous strand mat is produced by stitch the warp and weft knitted fabrics together and bonded by the powder adhesive bonding, thickness and fracture strength, but it is different from the generally felt, yarn density is uniform; the roving tension is uniform, the latter in a certain extent replace the continuous strand mat, when chopping, chopping fabric will not adhere to the knife roller. Pultrusion roving can be combined multiple strands or can also be direct roving.

- 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.

- The short cut fiber is used in the molding sheet or the molding compound, and also put it in the position of the hand paste glass fiber reinforced plastic with short cut fiber.

- It is mainly made by polyacrylonitrile and asphalt spinning, surface treatment and sizing process. The disparity in the domestic low-level product is small, carbonization (followed by graphite). The disparity between domestic and foreign is very large, and then by pre oxidation, but the high-end product(both high performance) can not do it, because it is too difficult.
- Q:Make 0.3 mm glass fiber short cut. What kind of fiberglass yarn is good?
- Application of chopped glass fiber:Glass fiber yarn is divided into ribbon and ribbon (with flash) is mainly plain weave. And the high-grade supply of glass fiber yarn for the manufacture of high strength, good dielectric properties of electrical equipment parts.Three-dimensional fabric three-dimensional fabric is relatively flat fabric, its structure from one-dimensional two-dimensional to three-dimensional, so that this reinforced composite has good integrity and profiling, greatly improving the glass fiber composites interlaminar shear strength and damage tolerance.Glass fiber short cut, dimensional stitched fabric, also known as knitted felt or woven felt, is different from ordinary fabrics and different from ordinary felt. The most typical seam woven fabric is a layer of warp, which overlaps with a layer of weft and weaves warp and weft together to form a fabric.

- 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℃.

- Glass fiber(English name is): It is a kind of excellent inorganic non-metallic materials, having the advantages of good insulation, strong heat resistance, good corrosion resistance, high mechanical strength, but the disadvantage of poor brittleness, poor abrasion resistance. It is founding by high tempersture with the materials of glass ball and waste glass, and wire drawing, winding and weaving process for production, the filament diameter ranges from several microns to twenty micron, the equivalent of a hair 1\20-1\5, and each bundle of fibers by hundreds or even thousands of root filaments. Usually it is treated as a reinforcing material of complex materials, electrical insulating materials and insulation materials, circuit board, etc. and widely used in various fields of the national economy. The tensile strength of glass fiber is high, and the elongation is small (3%).
