This square-cornered carbon fiber sunglasses has a classic square-cornered frame made of acetate with a three-dimensional bevel effect, cut by a diamond knife. The bridge is made of carbon fiber and metal trims, and there are carbon fiber trims on both sides of the bridge. And the carbon fiber trims were inlaid on the temples, giving the glasses a technological element.

Custom rivet hinges use retro-style hexagonal rivets. Black acetate, gold metal trims, and high-tech carbon fiber trims, so this pair of glasses has a unique style, retro, classic and fashionable.

Glasses manufacturer shares carbon fiber process: Why is carbon fiber so strong? The reason why carbon fiber has such high strength is mainly due to its unique material structure and fiber properties. Carbon fiber is a special fiber composed of carbon elements, and its diameter is usually around 5-10 microns. This extremely fine diameter makes the carbon fiber have fewer internal defects, which greatly enhances its tensile strength. In contrast, traditional steel and other metal materials have relatively low strength due to their large material volume and internal defects. In addition, the crystal structure of carbon fiber makes most of the carbon atoms arranged parallel to the long axis of the fiber, which further improves the strength-to-volume ratio of carbon fiber and increases the strength of carbon fiber.
