CARBON COMPOSITE MATERIAL DEVELOPMENT
MATERIAL DETERMINES THE PRODUCT QUALITY LEVEL
for carbon bicycle parts, there are several important elements always in our mind: carbon fiber tensile strength, tensile modulus, TOW, FAW, and epoxy system. Tensile strength means the break strength.Tensile modulus means stiffness.
TOW means how many carbon filaments are packaged together onto a single spool. It’s also the basic unit in the UNI-DIRECTIONAL (UD) fabric sheet. FAW means the fiber areal weight.
Together with specific epoxy systems, they determine together about 50% product performance and cost.
Other 50% is determined by structure design, lay-up schedule, and manufacturing processes
How to choose proper materials for different products?
Or how to choose the tensile strength, tensile modulus, TOW, and FAW ? Here, our emphasis is PROPER, which is a very professional and technical idea actually. Different products always have different purposes and applications.
So we need different materials to achieve the satisfactory results and proper manufacturing costs.
After many years’ testing and experience, we choose carbon fiber with 4800~5500Mpa strength, 220~300Gpa modulus, and 12K TOW from carbon fiber manufacturers like Toray, Japan.
And we have worked out our own epoxy systems and FAW system for our prepregs, which are also the key features of our products
