 pultruded fiberglass Raw materials and their applications

Glass fiber is an excellent performance of inorganic non-metallic materials, a wide range of advantages is good insulation, heat resistance, good corrosion resistance, high mechanical strength, but the disadvantage is brittle, poor wear resistance. It is made of glass ball or waste glass as raw material by high temperature melting, drawing, yarn, weaving and other processes made of its monofilament diameter of a few microns to twenty meters a few microns, the equivalent of a hair Of the 1 / 20-1 / 5, each bundle of fiber raw silk by hundreds or even thousands of monofilament composition. Glass fiber is usually used as a composite material in the reinforced materials, electrical insulation materials and insulation materials, circuit boards and other areas of the national economy.

Raw materials and their applications: glass fiber than organic fiber temperature is high, non-combustible, anti-corrosion, heat insulation, good sound insulation, high tensile strength, good electrical insulation. But the brittle, wear resistance is poor. Used to make reinforced plastic or reinforced rubber, as a reinforcing fiber glass fiber has the following characteristics, these features make the use of glass fiber far more than other types of fiber, the development speed is also far ahead of its characteristics are listed below:

(1) high tensile strength, elongation is small (3%).

(2) high elasticity coefficient, good rigidity.

(3) elastic limit within the large elongation and high tensile strength, so the absorption of large impact energy.

(4) for the inorganic fiber, with non-flammable, good chemical resistance.

(5) water absorption is small.

(6) scale stability, heat resistance are good.

(7) good processing, can be made into stocks, beams, carpets, weaving, and other different forms of products.

(8) transparent through the light.

(9) with a resin having a good adhesion to the surface treatment agent.

The characteristics of glass fiber: the concept of ordinary glass is a hard fragile objects, is not suitable as a structural material, but if it is made after the wire, its strength is greatly increased and has a soft, so with the resin given shape can finally become excellent Of the structural timber. Glass fiber with its diameter smaller its strength increased. (1) high tensile strength, elongation is small (3%), and the strength of the glass fiber is much higher than that of other types of fiber. ). (2) high elasticity coefficient, good rigidity. (3) elastic limit within the large elongation and high tensile strength, so the absorption of large impact energy. (4) for the inorganic fiber, with non-flammable, good chemical resistance. (5) water absorption is small. (6) scale stability, heat resistance are good. (7) good processing, can be made into stocks, beams, carpets, weaving, and other different forms of products. (8) Transparent through light. (9) Development of surface treatment agent with good resin adhesion. (10) cheap. Glass fiber classification: glass fiber according to the shape and length, can be divided into continuous fiber, fixed length fiber and glass wool; according to the glass composition, can be divided into alkali, chemical resistance, high alkali, alkali, high strength, Amount and anti-alkali glass fiber.
