1.Mechanical properties
We introduce thelightweight, high-strength, and high-elasticity functions that are the most noticeable and used functions of CFRP. CFRP can be said to be synonymous with “light and strong” materials. Carbon composite is composite material made of carbon fiber and epoxy resin, and in addition to the following grades, it is possible to design a special product that can suit each customer’s usage.| Specific gravity |

2.Thermal properties
About linear thermal expansion coefficient and thermal conductivityCFRP can manufacture molding products with excellent dimensional stability due to the low coefficient of thermal expansion of carbon fiber. In addition, thermal expansion “zero” is possible depending on the design. It also has better thermal conductivity than major plastics.
