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.
Functions of Glass Fiber:
1. Enhance rigidity and hardness: The addition of glass fiber can improve the strength and rigidity of plastics, but it also reduces toughness. Example: flexural modulus.
2. Improve heat resistance and heat deflection temperature: For example, glass fiber-reinforced nylon has a heat deflection temperature at least twice that of unreinforced nylon. Generally, glass fiber-reinforced nylon can withstand temperatures above 220°C.
3. Improve dimensional stability and reduce shrinkage.
4. Reduce warping deformation.
5. Reduce creep.
6. Affect flame retardancy due to the wick effect, which may interfere with flame retardant systems and reduce effectiveness.
7. Reduce surface gloss.
8. Increase moisture absorption.
9. Glass fiber treatment: The length of glass fiber directly affects material brittleness. Poorly treated short fibers reduce impact strength, while well-treated long fibers improve impact strength.
