Wear-Resistant and Well-Dispersed Glass Fiber for Brake Pads

Glass fiber is a high-performance inorganic non-metallic material with a wide variety of types. Its advantages include excellent insulation, strong heat resistance, good corrosion resistance, and high mechanical strength, but it is brittle and has poor wear resistance. It is manufactured from six types of ores—pyrophyllite, quartz sand, limestone, dolomite, boron-calcium ore, and boron-magnesium ore—through processes such as high-temperature melting, wire drawing, spooling, and weaving. The diameter of a single filament ranges from a few micrometers to over twenty micrometers, equivalent to 1/20 to 1/5 of a human hair strand. Each bundle of fiber filament consists of hundreds or even thousands of single filaments. Glass fiber is commonly used as a reinforcing material in composites, electrical insulation material, thermal insulation material, circuit substrates, and various other fields in the national economy.

Main Characteristics of Glass Fiber

Raw Materials and Applications: Glass fiber has higher temperature resistance than organic fibers, is non-flammable, corrosion-resistant, offers good thermal and acoustic insulation, high tensile strength, and excellent electrical insulation. It is used to manufacture reinforced plastics or reinforced rubber. As a reinforcing material, glass fiber has the following characteristics:

(1) High tensile strength, low elongation (3%).

(2) High elastic modulus and excellent rigidity.

(3) Large elongation within the elastic limit and high tensile strength, resulting in high impact energy absorption.

(4) As an inorganic fiber, it is non-flammable and has good chemical resistance.

(5) Low water absorption.

(6) Excellent heat resistance.

(7) Good processability, can be made into strands, bundles, mats, fabrics, and other forms.

(8) Transparent, allowing light transmission.

(9) Good adhesion with resins.

(10) Cost-effective.
