Described below are various glass fiber fabrics woven from glass fiber yarns.
(1) Glass cloth The glass cloth produced in China is divided into two types: alkali-free and medium-alkali. Most foreign countries are alkali-free glass cloth. Glass cloth is mainly used to produce various electrical insulating laminates, printed circuit boards, various vehicle bodies, storage tanks, boats, molds, and the like. Medium alkali glass cloth is mainly used for the production of coated packaging fabrics and for corrosion resistant applications. The properties of the fabric are determined by fiber properties, warp and weft density, yarn structure and texture. The warp and weft density is determined by the yarn structure and texture. The warp and weft density plus the yarn structure determines the physical properties of the fabric, such as weight, thickness and breaking strength. There are five basic textures: plain, twill, satin, rib and mat.
(2) Glass ribbon The glass ribbon is divided into a woven side belt and a non-woven side belt (burr belt). The main weave is plain weave. Glass ribbons are often used to make high-strength, dielectric-good electrical equipment components.
(3) Unidirectional fabric The unidirectional fabric is a four-striped or long-satin satin fabric woven from coarse warp yarns and fine weft yarns. It is characterized by high strength in the warp main direction.
(4) Three-dimensional fabric Three-dimensional fabric is a relatively flat fabric, and its structural features have evolved from one-dimensional two-dimensional to three-dimensional, so that the composite material with the reinforcement has good integrity and profiling, and greatly improves the composite. Interlaminar shear strength and damage tolerance of the material. It has been developed with the special needs of aerospace, aviation, weapons, ships and other departments, and its application has been extended to the automotive, sports equipment, medical equipment and other departments. There are five main categories: woven three-dimensional fabrics, knitted three-dimensional fabrics, orthogonal and non-orthogonal nonwoven three-dimensional fabrics, three-dimensional woven fabrics, and other forms of three-dimensional fabrics. The shape of the three-dimensional fabric has a block shape, a column shape, a tubular shape, a hollow truncated cone, and a variable thickness profiled section.
(5) The shape of the profiled fabric is very similar to the shape of the article to be reinforced, and must be woven on a dedicated loom. Shaped fabrics of symmetrical shape are: round caps, cones, caps, dumbbell-shaped fabrics, etc., and can also be made into asymmetrical shapes such as boxes and hulls.
(6) Grooved core fabric The core fabric is a fabric composed of two parallel fabrics joined by longitudinal vertical strips, and the cross-sectional shape may be triangular or rectangular.
(7) Fiberglass stitchbonded fabrics, also known as knitted or woven felts, differ from ordinary fabrics and felts of the usual sense. The most typical stitchbonded fabric is a layer of warp yarns which are overlapped with a layer of weft yarns, and the warp yarns and the weft yarns are woven together into a fabric by stitching. The advantages of the stitchbonded fabric are as follows: 1 It can increase the ultimate tensile strength of the FRP laminate, the delamination strength under the tension and the flexural strength; 2 reduce the weight of the FRP product; 3 smooth the surface of the FRP; 4 simplify Hand paste operation to improve labor productivity. This reinforcing material can replace continuous strand mat in pultrusion FRP and RTM, and can also replace gingham in the production of centrifugal glass tubing.
(8) The fiberglass insulation sleeve is woven into a tube with glass fiber yarn. It is coated with various insulation grade sleeves made of resin material. There are PVC resin glass fiber paint tubes. Acrylic glass fiber paint tube, silicone glass fiber paint tube, etc.
