Are carbon fiber glasses better or titanium?
In terms of weight, the titanium frame is very light. The specific gravity of the pure titanium frame is about 4.5g/cm3, and the specific gravity of the titanium alloy frame is about 8.9g/cm3. The pure titanium frame is lighter than the titanium alloy frame. However, carbon fiber glasses are lighter in weight. The carbon fiber glasses launched by LOHO are only 7.87g, which is very light to wear.
In terms of hardness, titanium has a high hardness, about twice that of stainless steel, twice that of iron, and six times that of aluminum. Carbon fiber is lighter than aluminum, harder than steel, and its strength is ten times that of iron.
In other respects, the titanium frame has the advantages of corrosion resistance, acid and alkali resistance, high stability, good elasticity, good toughness, and resistance to deformation. The carbon fiber frame has the advantages of corrosion resistance, high temperature resistance, radiation resistance, good elasticity, good flexibility, and abrasion resistance.
