Development of Carbon Fiber Reinforced Thermoplastic strand rod

Abstract

The purpose of the main research is to develop a more linear shape structural member using Carbon Fiber Reinforced Thermoplastic composite material. This paper will discuss the production stage begin with the instrumentation and machinery used in manufacturing, material selection for manufacturing the three-layer basic structure, and some improvement especially in material strength such as the tensile strength. In the process, fiber content and cavity ratio test, tensile strength test, alkali resistance test, temperature dependency test, weather resistance test, etc. is performed. Products that satisfy the expected performance were applied to the actual construction project. However, Carbon fiber composite materials are not included in designated building materials in the Japanese building standard. Therefore, it is difficult to apply the carbon fiber composite material in building construction in the present. An example case on a real project, carbon fiber composite materials used in structural member into the earthquake (horizontal) force resistant members.
