Fiberglass cloth
The following introduces various fiberglass cloths and fiberglass fabrics woven with fiberglass yarns.
Glass cloth
The glass cloth produced in my country is divided into two categories: alkali-free and medium-alkali. Most foreign countries are alkali-free glass cloth
Glass cloth is mainly used to produce various electrical insulation laminates, printed circuit boards, various vehicle body storage tanks, boat molds, etc. Medium-alkali glass cloth is mainly used in the production of plastic-coated packaging cloth and in corrosion-resistant applications. The characteristics of the fabric are determined by fiber properties, warp and weft density, yarn structure and weave pattern. The warp and weft density is determined by the yarn structure and weave pattern. The warp and weft density plus the yarn structure determine the physical properties of the fabric, such as weight, thickness and breaking strength. There are five basic weaves: plain weave
Similar to gingham twill, general + degree satin weave, similar to unidirectional cloth
Ribbed fiberglass mesh
The main weave and mat weave are similar to Oxford cloth< br/>.
Glass fiber tape
It is divided into woven edge tape, plain edge tape and non-woven edge tape. The main weaving method of raw edge tape is plain weave. Alkali-free glass fiber tapes are often used to manufacture electrical equipment components with high strength and good dielectric properties.
Fiberglass unidirectional fabric
, unidirectional fabric
The unidirectional fabric is a four-warp broken satin or long-axis satin woven with thick warp yarns and fine weft yarns Textured fabric is characterized by high strength in the main direction of warp yarns. There are also glass fiber single weft fabrics, with two weaving methods: warp knitting and woven. The characteristics are that thick weft yarns, fine warp yarns, and glass fiber yarns are all fed in the weft direction, and they have the characteristics in the weft direction. high strength.
Compared with flat fabrics, glass fiber three-dimensional fabrics have structural characteristics that have developed from one-dimensional and two-dimensional to three-dimensional, so that composite materials using them as reinforcements have good integrity and imitation. shape, greatly improving the interlaminar shear strength and damage tolerance of composite materials. It was developed with the special needs of sectors such as aerospace, aviation, weapons, and ships, and its application has now been extended to sectors such as automobiles, sports equipment, and medical equipment. There are mainly five categories of woven three-dimensional fabrics, knitted three-dimensional fabrics, orthogonal and non-orthogonal non-woven three-dimensional fabrics, three-dimensional knitted fabrics and other forms of three-dimensional fabrics. The shapes of three-dimensional fabrics include block columnar tubular hollow truncated cones and variable thickness special-shaped sections.
Fiberglass special-shaped fabric The shape of the special-shaped fabric is very similar to the shape of the product it is to reinforce, and it must be woven on a special loom. Symmetrically shaped special-shaped fabrics include round covers, cone caps, dumbbell-shaped fabrics, etc., and can also be made into asymmetric shapes such as box hulls.
Glass fiber grooved core fabric Grooved core fabric is a fabric composed of two layers of parallel fabrics connected by longitudinal vertical strips. Its cross-sectional shape can be triangular, rectangular, or honeycomb structure

Fiberglass stitched fabric
Also known as knitted mat or woven mat, it is different from ordinary fabrics and mats in the usual sense. The most typical stitch-bonded fabric is a layer of warp yarns and a layer of weft yarns overlapped together, and the warp yarns and weft yarns are woven together to form a fabric through stitching. The advantages of stitchbonded fabrics are as follows ① It can increase the ultimate tensile strength of FRP laminated products
, anti-delamination strength under tension and flexural strength
② Reduce the weight of FRP products ③ The flat surface makes the FRP surface smooth ④ Simplify the hand lay-up operation and improve labor productivity
. This reinforcing material can replace continuous strand mats in pultruded FRP and R, and can also replace grid cloth in centrifugal FRP pipe production.
