Introduction Of Glass Fiber Cloth And Its Application In Different Industries

1, Glass Fiber Non-Twist Roving Fabric (Glass Fiber Check Cloth)

Glass fiber check cloth is non-twist roving plain fabric, is an important base material of hand paste glass fiber reinforced plastic. The strength of the plaid cloth is mainly in the warp and weft direction of the fabric, for the occasion of requiring high warp or weft strength, it can also be woven into one-way cloth, which can be arranged in the warp or weft more untwisted roving, single warp cloth, single weft cloth. Untwisted roving is made by bunching parallel strands or parallel monofilaments. Untwisted roving can be divided into E-GLASS untwisted roving and C-GLASS untwisted roving. The diameter of the glass fiber used in the production of glass roving is from 12 to 23um. The number of untwisted roving is from 150 to 9600 (tex). Untwisted roving can be directly used in some composite process forming methods, such as winding and pultrusion processes, because of its uniform tension, it can also be woven into untwisted roving fabric, and in some applications, the untwisted roving can be further shortened.

The quality requirements of the gingerbread are as follows :① The fabric is uniform, the cloth edge is flat and straight, the cloth surface is flat and match-like, without stains, fuzziness, creases, wrinkles, etc.; ② Warp and weft density, area weight, fabric and roll length meet the standard; ③ Winding on a firm paper core, winding neatly; (4) Rapid and good resin permeability; ⑤ The dry and wet mechanical strength of the laminate material made of fabric should meet the requirements. The composite material coated with plaid cloth is characterized by low interlaminar shear strength and poor compressive and fatigue strength.

2, Glass Fiber Felt Cloth

(1) Cut the glass raw silk (sometimes also with no twist roving) cut into 50mm long, spread it randomly but evenly on the mesh belt, and then apply milk, liquid binder or powder unbonded agent to heat curing and bond into short cut raw silk felt. Chopped felt is mainly used in hand paste, continuous plate making and die pressing and SMC process. The quality requirements of the cut yarn felt are as follows:

1.The area quality is uniform along the width direction;

2.The cut strands are evenly distributed in the felt surface, no large holes are formed, and the binder is evenly distributed;

3.With moderate dry felt strength;

4.Excellent resin infiltration and penetration.

(2) Continuous filament felt the glass filament formed in the process of wire drawing or the continuous filament retreated from the cylinder in a figure-8 spread on the continuous moving mesh belt, and the powder binder bonding is formed. The fiber of continuous glass fiber filament felt is continuous, so its strengthening effect on composite material is better than that of short cut felt. It is mainly used in pultruding, RTM, pressure bag and glass felt reinforced hot plastic (GMT) process.

(3) Surface felt glass fiber reinforced plastic products usually need to form a rich resin layer, which is generally achieved with alkali glass surface felt. This kind of felt is made of medium alkali glass (C), so it gives the glass steel chemical resistance, especially acid resistance, and because the felt is thin and the glass fiber diameter is small, it can also absorb more resin to form a rich resin layer, which covers the glass fiber reinforcement material (such as check cloth), and plays a surface modification role.

(4) Needle felt Needle felt or divided into short fiber needle felt and continuous raw thread needle felt. Staple fiber needle felt is a glass fiber roving cut into 50mm pieces, randomly laid on the substrate pre-placed on the conveyor belt, and then needled with a barb needle, the needle stabbed the staple fiber into the substrate, and the crochet needle brought up some of the fibers to form a three-dimensional structure. The base material used can be thin fabric of glass fiber or other fibers, and this kind of needle felt has a fuzzy feeling. Its main uses include thermal insulation materials, lining heat materials, filter materials, and can also be used in the production of FRP, but the strength of FRP is low and the use range is limited. Another kind of continuous primary thread needled felt is the three-dimensional structure of the felt in which the continuous glass primary thread is randomly thrown on the continuous mesh belt by a wire throwing device and then needled by a needle plate. This kind of felt is mainly used in the production of glass fiber reinforced thermoplastic stampable sheets.

(5) stitched felt cut glass fiber from 50mm or even 60cm long can be stitched into short fiber or long fiber felt, the former can replace the traditional binder bonded short felt in several uses, the latter to a certain extent instead of continuous filament felt. Their common advantage is that they do not contain binders to avoid pollution in the production process, while the penetration performance is good and the price is low.

3, Glass Fiber Cloth The Following Introduces A Variety Of Glass Fiber Cloth Woven With Glass Fiber Yarn, Glass Fiber Fabric.

(1) Glass fiber cloth Glass fiber cloth produced in China is divided into two categories: alkali-free and alkali, and most foreign countries are E-GLASS alkali-free glass cloth. Glass fiber cloth is mainly used in the production of various electrical insulation laminates, printed circuit boards, various vehicle bodies, storage tanks, boats, molds and so on. Medium alkali glass fiber cloth is mainly used for the production of plastic-coated packaging cloth, and for corrosion resistance occasions. Fabric properties are determined by fiber properties, warp and weft density, yarn structure and weave. The warp and weft density is determined by the fabric structure and weave. The warp and weft density and the yarn structure determine the physical properties of the fabric

Properties such as weight, thickness and breaking strength.

There are five basic weaves: plain plan(similar to plaid), twill twi(generally +-45 degrees), satin statin(similar to one-way fabric), ribbed leno(mainly glass mesh fabric) and matts(similar to Oxford fabric).

(2) The glass fiber strip is divided into woven side strips (light edge strips) and non-woven side strips (raw edge strips). Alkali-free glass 纴 is often used in the manufacture of high-strength, good dielectric properties of electrical equipment parts.

(3) Glass fiber unidirectional fabric, unidirectional fabric in which the single warp fabric is a coarse warp and fine weft woven into four broken satin or long axis satin fabric, which is characterized by high strength in the warp main direction of 0 degrees. There are also glass fiber single weft cloth, there are two kinds of warp knitting and machine weaving, characterized by thick weft yarn, fine warp yarn, glass fiber yarn are fed in the weft, at 90 degrees latitude with high strength.

(4) glass fiber three-dimensional fabric Three-dimensional fabric is relative to flat fabric, its structural characteristics have developed from one-dimensional two-dimensional to three-dimensional, so that the composite material as the reinforcement has good integrity and shape copying, greatly improving the interlayer shear strength and damage tolerance of the composite material. It is developed with the special needs of aerospace, aviation, weapons, ships and other departments, and its application has been expanded to automobiles, sports equipment, medical equipment and other departments. There are five main categories: woven 3D fabrics, knitted 3D fabrics, orthogonal and non-orthogonal non-woven 3D fabrics, 3D woven fabrics and other forms of 3D fabrics. The shape of three-dimensional fabric includes block, column, tube, hollow truncated cone and variable thickness shaped section.

The shape of the special-shaped fabric is very similar to the shape of the product it is intended to enhance, and must be woven on a special loom. Symmetrical shape of the special-shaped fabric are: cap, cone, cap, dumbbell fabric, etc., can also be made into boxes, hull and other asymmetric shapes.

(6) Glass fiber channel core fabric Channel core fabric is composed of two layers of parallel fabric, connected by vertical vertical bars of fabric, its cross-section shape can be triangular, rectangular, honeycomb structure.

(7) Glass fiber stitched fabric is also known as knitted felt or woven felt, it is different from ordinary fabric, but also different from the usual sense of felt. The most typical stitched fabric is a layer of warp and a layer of weft heavy together, by sewing the warp and weft woven together into fabric. The advantages of braided fabric are as follows: (1) It can increase the ultimate tensile strength of FRP laminates, the delamination strength under tension and the bending strength; (2) Reduce the weight of FRP products; ③ The surface is smooth to make the surface of the glass plate smooth; ④ Simplify hand paste operation, improve labor productivity. This reinforced material can be used in pultrusion FRP and RTM! In place of continuous raw silk felt, can also be used in the production of centrifugal glass tube instead of gingerbread.

4, combined glass fiber cloth glass fiber cloth, cut yarn felt, continuous yarn felt, untwisted roving fabric and untwisted roving, etc., according to a certain order combined reinforcement materials, there are generally the following:

(1) Cut raw silk felt + non-twist roving fabric

(2) Cut yarn felt + untwisted roving cloth + cut yarn felt

(3) Cut raw silk felt + continuous raw silk felt + cut raw silk felt

(4) Cut raw felt + random untwisted roving

(5) Cut raw silk hub or cloth + one-way non-twist roving

(6) Cut raw silk + surface felt

(7) Glass fiber cloth + one-way non-twist powder yarn or glass fine rod + glass fiber cloth

Glass fiber cloth is mostly used in hand paste into the process, glass fiber reinforced material grid cloth is mainly in the hull, storage tanks, cooling towers, ships, vehicle grooves, building structural materials.
