摘　　要：介绍了舰船玻璃钢夹层结构原材料 (包括玻璃钢、聚氨酯泡沫塑料、聚氯乙烯泡沫塑料、胶合板、松木等 )的基本性能。作者在进行了大量结构件试验的基础上 ,结合国内外已有之研究成果 ,提出了有关舰船玻璃钢夹层结构强度设计中的若干简明而实用的计算公式。局部强度设计包括 :弯剪强度 ;骨材的弯曲强度 ;纵桁的剪切强度。总体强度设计包括 :板的压缩稳定性计算 (有面板皱曲失稳计算、芯子剪切弯曲失稳计算、胶合板芯子分层后失稳极限强度计算 ) ;舷侧夹层结构板和纵舱壁夹层结构板面内剪切计算 ;The raw material properties of FRP sandwich construction for ship, including the tensile, compression and shear properties of FRP, polyurethane (PU) foam plastics, polyvinyl chloride (PVC) foam plastics, plywood, pinewood, are presented in this paper. For foam plastic, the statistical equations of the relation among the flatwise compression, shear properties and densities are also given. The local strength design of ship hull includes the flexural-shear strength design of sandwich construction plate, the flexural strength design of sandwich construction framework and the shear strength design of sandwich construction longitudinal stiffener. The overall strength design of ship hull includes three parts: 1 the compression stability calculations of sandwich construction plate, such as wrinkling calculation, core shear flexure—buckling calculation after plywood core delaminetion; 2 the plane shear strength calculations of the side sandwich construction plate of ship hull and longitudinal sandwich panel of bulkhead; 3 the calculations of overall longitudinal flexure and center section modulas. The properties, statistical equations and calculation formulas presented in this paper may be used for design of sandwich construction of warship and ship.
