To understand the difference between carbon fiber glasses and fiber glasses, we need to understand the difference between carbon fiber and glass fiber. As a high-quality glasses manufacturer in Shenzhen, we have a deep research and understanding of the materials of glasses. This article will learn about the difference between carbon fiber glasses and fiber glasses from the aspects of the composition, properties, performance, process, appearance and application of these two materials. The following is a detailed explanation of their differences.
The difference between carbon fiber glasses and fiber glasses 1: Different material composition and properties.
Carbon fiber: The main component is a fiber material with a high carbon content, which is composed of carbon elements. It has the advantages of high strength, high modulus, high tensile strength and bending strength, and low thermal expansion coefficient, but it is relatively brittle and easy to break. The specific strength and specific modulus of carbon fiber are particularly high, which is suitable for fields that require extremely light and strong materials.
Glass fiber: It is a fiber material drawn from glass melt. It has high tensile strength and compression strength, but poor elastic modulus and thermal expansion coefficient, and is not suitable for high temperature use.
The difference between carbon fiber glasses and fiber glasses 2: different performance.
Rigidity comparison: Carbon fiber performs better than glass fiber in rigidity, that is, carbon fiber has a stronger ability to resist elastic deformation when subjected to force.
Tensile strength comparison: Carbon fiber has obvious advantages in tensile strength. The tensile strength of general-purpose carbon fiber can reach 1000MPa, and high-strength carbon fiber can even reach 3500MPa, while the tensile strength of high-strength glass fiber is usually around 2800MPa.
Durability comparison: Durability includes many aspects, such as high temperature resistance, low temperature resistance, acid and alkali resistance, corrosion resistance, impact resistance, etc. In these aspects, glass fiber and carbon fiber have their own advantages and disadvantages. For example, glass fiber is better in high temperature resistance, while carbon fiber is slightly better in impact resistance. In terms of overall service life, carbon fiber is longer, but in specific use environments, an exact comparison cannot be made.
Conductivity comparison: Carbon fiber has better conductivity, which is particularly important in electrical applications.
The difference between carbon fiber glasses and fiber glasses 3: different production processes.
Carbon fiber: The production process is complex, including three stages of weaving, prepreg and molding. The energy consumption in the production process is large and the technical threshold is high.
Glass fiber: The production is relatively simple, the technology is mature and easy to obtain.
The difference between carbon fiber glasses and fiber glasses 4: appearance and weight comparison.
1. Observe the surface of the fiber, and you can touch the surface texture with your hands. The surface of glass fiber is smoother, while the surface of carbon fiber is rougher and feels rougher.
2. Difference in fiber color. Glass fiber is usually colorless or white, while carbon fiber is black or dark gray. In some cases, carbon fiber may have a metallic luster, while the surface of glass fiber usually presents a translucent or milky appearance.
3. Difference in fiber flexibility. Glass fiber has relatively high elasticity and can stretch when bent without breaking easily. Carbon fiber is brittle, easy to break, and may have cracks and breaking points.
4. Difference in fiber weight. Glass fiber is usually lighter than carbon fiber in the same volume. This is due to the higher density of carbon fiber.
The difference between carbon fiber glasses and fiber glasses 5: different prices and costs.
The price of glass fiber is lower than that of carbon fiber. This is mainly because glass fiber was popularized earlier, the production process is simpler, and the production capacity is larger, while the production process of carbon fiber is more complicated, the production capacity is not so large, and the excellent performance of carbon fiber in specific strength and specific modulus makes its price naturally higher.

In terms of application, carbon fiber is mainly used in fields with high requirements for material performance due to its excellent performance, such as aviation, aerospace, ships, automobiles, sports equipment, etc., while glass fiber is widely used in construction, molds, electronics, electrical appliances, light industry and other fields due to its low cost and moderate performance. When these two materials are used to make glasses, they are carbon fiber glasses and fiber glasses. So, can you distinguish between carbon fiber glasses and fiber glasses?
