Electronic Devices: The properties of carbon fiber make it widely used in electronic devices, such as in phone cases, laptop shells, tablet cases, and other products where the presence of carbon fiber can be observed.
Aramid Fiber: In the field of electronics and electrical engineering, aramid fibers have high strength and modulus, as well as a low dielectric constant. They have good electromagnetic wave transmission, and under the same rigidity conditions, the thickness of radar antenna protective covers made of aramid composite materials can be reduced by 30% compared to fiberglass composite materials. The electromagnetic wave transmission rate increases by 10%. Aramid, when combined with resins like epoxy, phenolic, and polyimide, in laminated substrates, exhibits a high coefficient of thermal expansion matching that of ceramics. This prevents cracking under thermal expansion and contraction, making it suitable for the production of special printed circuit boards in surface mount technology, contributing to the miniaturization and lightweighting of electronic devices. Aramid fiber’s high strength and heat resistance make it suitable for use as a “tension member” in optical fibers, protecting delicate and fragile optical fibers from elongation deformation when subjected to tension, without affecting light transmission. Composite products of aramid fiber and carbon fiber exhibit good processability and semiconductor properties, and they can withstand high temperatures. They are often used to reduce the electric field in high-voltage devices. Aramid paper, after impregnation with insulating varnish, exhibits good insulation properties and is used as insulation material for heat-resistant motors when combined with natural mica sheets.
Phone Cases: Aramid fibers are widely used in the manufacturing of phone cases due to their lightweight, abrasion resistance, and heat resistance, providing good protective performance and a comfortable feel.
Carbon Fiber and Aramid Fiber can both be used in the manufacture of flashlights, but their applications and effects may vary.
Carbon Fiber: Carbon fiber is a lightweight and high-strength material, making it suitable for manufacturing flashlight casings that are both lightweight and durable. However, carbon fiber is conductive and may affect the performance of electronic devices.
Aramid Fiber: Aramid fiber is a high-strength material that can be used to manufacture flashlight casings, providing excellent protective performance. Aramid fiber is a good insulator, with a dielectric strength of up to 20kV/mm, so it does not affect the electronic performance of flashlights.
In addition, aramid fiber and carbon fiber can be combined for processing, used in materials to reduce the electric field in high-voltage devices. This may have some impact on the electronic performance of flashlights, but the specific effects may vary depending on product design and manufacturing processes.
