인발 성형법을 이용한 복합소재 신호등 부착대의 C/GFRP 구조적 안정성에 관한 연구

As the climate changes rapidly due to warming, it is becoming very important to ensure the stability ofenvironmental structures. It is necessary to choose a material that withstands repeated external forces (windloads) and satisfies members and joints that have energy absorbing power. Even if the strength of the trafficlight attachment is sufficient, if the rigidity is insufficient, there is a limit to the displacement during strongwinds. Excessive deformation may cause damage and fall, resulting in a safety accident. The author intends tostudy mechanical properties and resistance to external environment as a structural material capable ofwithstanding wind load (50m/sec) by fabricating a C/GFRP composite traffic light attachment using the pultrusionmethod (Pultrusion).
