Abstract

This paper presents analytical expressions for the determination of out of plane thermo-elastic properties for conventional laminated composite plates. The approach follows that commonly accepted for in-plane properties. Results over a variety of lay-ups reveals that it is poor assumption to use transverse tape lamina properties to represent out of plane laminate properties for laminates with more than 10% plies oriented off-axis($90^{\circ}$) from uniaxial or for laminates with angle plies of $15^{\circ}$ or greater.

본 논문은 적층된 복합재 라미네이트의 두께방향(out-of-plane) 열탄성 물성치 계산식에 관하여 서술하였다. 다양한 적층패턴을 유도된 계산식에 적용한 결과, 섬유방향이 단방향 0도로 구성된 라미네이트에서 총 플라이수 중 10% 이상이 모두 90도 섬유방향으로 이루어져 있거나, 또는 15도 이상의 섬유방향으로 형성된 적층패턴을 가지는 라미네이트(Laminate)의 두께방향 물성치를 복합재 라미나(lamina)의 단섬유방향과 직교하는 물성치(transverse property)로 가정하는 것은 적절하지 않은 것으로 나타났다.
