상용화 마찰재를 사용하여 고온 열화에 대한 원료들의 영향을 연구하였다. 제한된 영역에서의 실험계획법에 의해 25개의 마찰재가 제작되었으며, 축소 마찰 시험기로 마찰, 마모특성을 조사하였다. 아라미드 섬유, 흑연, 구리섬유는 열화에 대한 저항성을 향상시켰으며, 반면 삼황화 안티몬, 지르콘은 열화현상을 가속시키는 것으로 나타났다. 이러한 결과는 각 원료들이 계면에 미치는 영향이 각기 다르기 때문으로 사료된다. 아라미드 섬유, 흑연, 구리섬유등은 계면을 안정화 시켰으며, 삼황화 안티몬, 지르콘등은 고온에서 불안정한 계면을 형성시키는 것으로 나타났다.

In this study, strength, stiffness and confinement effect with stress-strain and stress-volumetric strain curves for improved uniaxial compressive behavior of RC circular columns laterally confined with prestressing aramid fiber strap were experimentally investigated. The test variables were the specimens with or without axial reinforcing bar and the number and spacing of strap, prestressing level, the types of reinforcing fiber (CFS, GFS). As a result, the failure type of the columns was very stable and strength increase rate was about 73% comparison with the general RC columns. Moreover, the strain increase rate is very small and the axial displacement confinement effect was very effective compared with existry methods (CFS, GFS), the initial and final lateral confinement effect was excellent.
