以硅酸钙板为面板、纤维增强泡沫混凝土为芯材制备了泡沫混凝土复合墙板，研究了聚丙烯纤维掺量和泡沫混凝土容重对复合墙板受压性能的影响; 并通过对受压应力
应变曲线回归分析，获得了应力应变曲线方程． 结果表明: 随芯材中纤维掺量的增大( 0 ～2 kg /m³ ) ，复合墙板受压破坏时芯材的裂缝减少，抗压强度提升了76．08%，受压韧性指数提高了30． 03%; 随芯材容重的增大( 400 ～ 600 kg /m³ ) ，复合墙板受压破坏时逐渐从单一破坏转变为整体破坏，抗压强度大幅提高，受压韧性指数增幅较小; 复合墙板受压应力应变曲线可分为弹性应变、应力硬化、应变软化和破坏4 个阶段，峰值应变随纤维掺量的增加而增加，芯材容重对峰值应变的影响较小; 复合墙板在受压条件下会出现界面裂缝和分层现象．

Foamed concrete sandwich panels were prepared by using calcium silicate boards as the skin layer and fiber-reinforced foamed concrete as the core material.Then,the influence of the polypropylene fiber dosage and the core material density on the structure performance of the prepared sandwich panels under compression was investigated,and the stress-strain curve equations were established through the regression analysis of compressive stressstrain curves.The results show that ( 1) as the fiber dosage in the core material increases from 0 to 2 kg /m³,the crack number of the core material decreases,while the compressive strength and the compressive toughness index increase respectively by 76. 08% and 30. 03%; ( 2) as the core material density increases from 400 kg /m³ to 600 kg /m³,the failure mechanism of the prepared sandwich panels gradually changes from single damage to overall destruction,with a greater increase in the compressive strength but a smaller increase in the compressive toughness index; ( 3) the stress-strain curves of the prepared sandwich panels can be divided into four stages,namely,elastic strain,stress hardening,strain softening and failure; ( 4) the peak strain increases with the increase of the fiber dosage,while the core material density has less effect on the peak strain; and ( 5) interface cracks and a delamination phenomenon may occur in the prepared sandwich panels under compression.
