탄소섬유 블레이딩 강체의 직조조건에 따른 강체의 물성 변동에 대한 고찰 = Investigation into the Variation of Physical Properties in Carbon Fiber Composites (CFRP) according to Braiding Conditions

다국어 초록 (Multilingual Abstract)

This study investigated the braiding weaving method and the resulting tensile and flexural properties of rigid bodies based on different types of carbon fiber yarns. The research examined the physical properties of rigid bodies at various weaving angles using T700, T800, and PITCH-based yarns. The results revealed that the type of carbon fiber yarn directly influences the tensile characteristics of the rigid body. T800 yarn exhibited high strength, while PITCH-based yarn demonstrated high elongation, confirming that each yarn maintained its relative characteristics. The study found that the properties of braided rigid bodies vary depending on the yarn properties and weaving angle. At 0 degrees (UD direction), the rigid bodies displayed pure carbon fiber characteristics. However, as the weaving angle increased, a transition towards polymer resin properties was observed. The investigation confirmed a significant decrease in both tensile and flexural strength as the weaving angle increased. The results obtained through this study will serve as important basic data for setting the correct process conditions in the production of carbon fiber rigid bodies using the braiding method.
