Parametric study on design of sandwich structures composing of fibre reinfoced composites, polymer foam and resin concrete

섬유강화 복합재료, 고분자 포움 및 레진 콘크리트로 구성된 샌드위치 구조 설계를 위한 파라메트릭 연구

In this paper sandwich structures like beams and plates are optimised by using parametric study. The structures are composed of fibre reinforced composites for facial material and resin concrete and PVC foam for core materials. The stacking sequences and thickness of the composites are controlled as major parameters to find out the optimal condition for machine tool components. For the plate structure for machine tool bed composites-skined sandwich structure which has several ribs are proposed to enhance both directional bending stiffnesses at the same time. From the results optimal configuration and materials for high precesion machine tools are proposed.
