Knowledge Of Glass Fabric Woven With Glass Fiber Yarns

The following is an introduction.

All kinds of glass fabric woven by yarns.

(1) glass cloth made in China consists of two types of glass cloth, alkali free and medium alkali, and most of them are alkali free glass cloth.

Glass cloth is mainly used to produce all kinds of electrical insulation laminates, printed circuit boards, various vehicle bodies, tanks, boats, moulds, etc.

Medium alkali glass cloth is mainly used for producing plastic coated cloth and used for corrosion resistant occasions.

The fabric's properties are fiber properties, warp and weft density,

The structure and texture are determined.

The density of warp and weft is determined by yarn structure and texture.

The warp and weft yarn structure determines the physical properties of fabrics, such as weight, thickness and breaking strength.

There are five basic weaves: plain, twill, satin, rib and pattern.

(2) the glass ribbon is divided into a selvage belt and a selvedge belt.

Glass ribbons are often used in manufacturing electrical equipment parts with high strength and good dielectric properties.

(3) unidirectional fabric unidirectional fabric is a kind of four broken satin or long axis satin fabric made of coarse warp and fine weft yarn.

It is characterized by high strength on warp yarn.

(4) the three-dimensional fabric of three-dimensional fabric is relative to plane fabric. Its structural characteristics develop from one dimension to two dimensions, so that the composite material with this reinforcement has good integrity and profiling, and greatly improves the interlaminar shear strength and damage tolerance of the composite.

It has developed with the special needs of aerospace, aviation, weapons, ships and other departments. At present, its application has expanded to automobile, sports equipment, medical devices and other departments.

There are five main types: woven 3D fabric, knitted 3D fabric, orthogonal and non orthogonal non-woven 3D fabric, 3D braided fabric and other forms of three-dimensional fabric.

The shape of the three-dimensional fabric is massive, columnar, tubular, hollow truncated and variable thickness section.

(5) the shape of the special shaped fabric is very similar to the shape of the product it wants to enhance. It must be woven on a special loom.

The symmetrical shape special-shaped fabrics are: round cap, cone, cap, dumbbell shaped fabric, etc., and can also be made into asymmetric shapes such as boxes and hull.

(6) the core fabric of the core fabric is made up of two parallel fabrics, which are connected by vertical vertical bars. The cross section can be triangular or rectangular.

(7) glass fiber stitching knitted fabric is also known as

Or woven felt, it is different from ordinary fabrics, but also different from the usual sense of felt.

The most typical stitch knitted fabric is a layer of warp overlapped with a layer of weft yarn, woven through the stitch to weave the warp and weft together into fabric.

The advantages of stitched fabrics are as follows:

It can increase the ultimate tensile strength of laminated products, tensile strength and flexural strength under tension. 2. Lighten the weight of FRP products; (3) smooth surface of FRP products; (4) simplify manual paste operation and increase productivity.

This reinforced material can replace the continuous strand felt in pultrusion FRP and RTM, and can also replace the square cloth in the production of centrifugal FRP.
