In terms of durability, carbon fiber and glass fiber each have their own characteristics and advantages, making it difficult to generalize which is more durable. The following is a detailed comparison of their durability:
High-temperature resistance
Glass fiber: Glass fiber performs exceptionally well in high-temperature environments, maintaining stable performance over extended periods. This makes it widely used in high-temperature industrial applications.
Carbon fiber: While carbon fiber does not match glass fiber in high-temperature resistance, it can still maintain good performance within a certain temperature range (e.g., -180°C to 200°C). However, in high-temperature environments (e.g., above 300°C), carbon fiber’s performance may be affected.
Corrosion Resistance
Glass fiber: Glass fiber exhibits excellent corrosion resistance, capable of withstanding the erosion of various acids, alkalis, salts, and other chemical substances. This makes glass fiber widely used in corrosive environments such as chemical and marine applications.
Carbon fiber: Carbon fiber also has good corrosion resistance, but due to the presence of microscopic cracks or pores on its surface, certain corrosive substances may penetrate into it, affecting the long-term performance of carbon fiber. However, for most application scenarios, the corrosion resistance of carbon fiber is still sufficient.
Impact resistance
Glass fiber: Glass fiber has relatively good impact resistance and can withstand a certain degree of impact and vibration. However, under severe impact, glass fiber may fracture or break.
Carbon fiber: Carbon fiber also has excellent impact resistance, with its high strength and toughness enabling it to maintain good integrity under impact. However, carbon fiber may also fracture under extreme impact, but the likelihood of fracture is lower compared to glass fiber.
Overall service life
Glass fiber: Glass fiber typically has a long service life, especially in suitable application environments. However, due to various factors (such as oxidation and corrosion) over extended use, its performance may gradually deteriorate.
Carbon fiber: Carbon fiber also has a long service life and may even outperform glass fiber in certain application scenarios. Its high strength and corrosion resistance enable it to maintain good performance stability in harsh environments. However, carbon fiber is more expensive, and in some cases, additional protective measures may be required to extend its service life.
In summary, carbon fiber and glass fiber each have their own characteristics and advantages in terms of durability. When selecting materials, it is necessary to comprehensively consider factors such as high-temperature resistance, corrosion resistance, impact resistance, and overall service life based on specific application scenarios and requirements.
