Carbon fiber has a density of only 1.7g/cm3 (40% lighter than aluminum) and is 10 times stronger than steel. From aerospace to fishing rods and luggage, its high price is due to its complex manufacturing process, not blind overpricing. Understanding its four key characteristics—lightweight, strong, high-temperature resistant, and corrosion resistant—and avoiding common misconceptions about grades and materials will allow you to make informed purchases and avoid wasting money.

High-tech fiber materials have become deeply integrated into daily life, with applications expanding from personal protective equipment to energy, medical, and smart devices. The following explanation focuses on specific material types and application scenarios:

Carbon fiber cloth, also known as carbon fiber cloth or carbon fiber fabric, is a unidirectional carbon fiber reinforcement product woven from 12K carbon fiber filaments (each bundle contains 12,000 carbon filaments). The thickness is mainly 0.111mm (200g) and 0.167mm (300g), and the width covers 100mm, 150mm, 200mm, 300mm, 500mm and special customized sizes. It has the characteristics of high strength, low density and corrosion resistance [1] [4-5]. This material is combined with concrete components through matching impregnation adhesive and is widely used in buildings, bridges and tunnels.
