Properties and Applications of Glass Fibers for Reinforcing Composite Materials

Properties and Applications of Glass Fibers for Reinforcing Composite Materials

  In the past more than half a century, fiber-reinforced composite materials have been widely used due to their excellent properties, and the important role of reinforcing fibers in composite materials is self-evident.

  At present, the most common reinforcing fibers include glass fibers, aramid fibers, carbon fibers, etc. This article will introduce the characteristics and applications of glass fibers for composite reinforcement.

What is fiberglass?

  Glass fibers are widely used due to their cost-effectiveness and good properties, mainly in the composites industry. Glass fibers have both filaments and short fibers or flocs. Glass filaments are commonly used in composite materials, rubber products, conveyor belts, tarpaulins, etc. Short fibers are mainly used in non-woven felts, engineering plastics and composite materials.

  Attractive physical and mechanical properties of glass fibers, ease of manufacture and compatibility with carbon fibers

The low cost of dimensional comparison makes it the material of choice for high performance composite applications. Glass fibers are composed of oxides of silica. Glass fibers have excellent mechanical properties such as being less brittle, high strength, low stiffness and light weight.

glass fiber properties

  The main characteristics of glass fiber include the following aspects:

  Not easy to absorb water: Glass fiber is water repellent and is not suitable for clothes, because sweat will not be absorbed, making the wearer feel wet; because the material is not affected by water, it will not shrink.

  High Strength: Fiberglass is extremely strong, almost as strong as Kevlar. However, when the fibers rub against each other, they break and cause the fabric to take on a shaggy appearance.

  Insulation: In short fiber form, fiberglass is an excellent insulator

  Heat Resistance: Glass fibers have high heat resistance, can withstand temperatures up to 315°C, they are not affected by sunlight, bleach, bacteria, mold, insects or alkalis.

Application of glass fiber

  Fiberglass is an inorganic material that does not burn and retains about 25% of its initial strength at 540°C. It is an excellent electrical insulating material. Fiberglass fabrics have properties such as low moisture absorption, high strength, heat resistance and low dielectric constant, making them ideal reinforcements for printed circuit boards and insulating varnishes.

  In textile form, this strength can be unidirectional or bidirectional, allowing flexibility in design and cost for a wide range of applications in the automotive market, civil construction, sporting goods, aerospace, marine, electronics, Home and wind energy.

They are also used in the manufacture of structural composites, printed circuit boards and various special-purpose products.
