Mr. Raja Kumar on Instagram: "Carbon fiber looks thin and light, but it’s one of the hardest materials to manufacture. Each strand is made from polymer fibers heated above 1,000°C, stretched, oxidized, and baked again to align carbon atoms perfectly. This process takes days, uses extreme energy, and even tiny defects can ruin the entire sheet. It doesn’t melt like metal. It resists heat, stress, and deformation. That precision… is what makes it expensive. In this video: • why carbon fiber resist
