Abstract

Pulp fibre foams are a potential alternative to porous polymers; however, their poor mechanical properties limit their application to packaging materials. We utilised the sandwich composite approach to produce panels (370 mm x 300 mm x 20 mm) comprising of pulp fibre foams and kraft liner papers to improve the mechanical properties of such foams. Two types of sandwich structures are produced: foam core sandwich panels and stiffened sandwich composites. The resulting sandwich structures materials have apparent densities ranging from 80 kg/m³ to 161 kg/m³. The mechanical properties are assessed in compression, three-point bending and double lap shear loading conditions. We show that pulp fibre foam sandwich structures possess significantly higher compression and flexural moduli and strengths when compared to pure pulp fibre foams. Stiffening the pulp fibre foam core further by incorporation of kraft liner paper stiffeners results in even higher mechanical, including lap shear, properties.

硬化纤维素夹层复合材料

纸浆纤维泡沫是多孔聚合物的潜在替代品；然而，它们较差的机械性能限制了它们在包装材料中的应用。我们采用夹心复合方法生产由纸浆纤维泡沫和牛皮衬纸组成的面板（370毫米x 300毫米x 20毫米），以改善这种泡沫的机械性能。产生了两种类型的夹层结构：泡沫芯夹层板和加筋夹层复合材料。由此产生的夹层结构材料的表观密度从80 kg/m3到161 kg/m3不等。在压缩、三点弯曲和双搭剪加载条件下对其力学性能进行了评价。我们表明，与纯纸浆纤维泡沫相比，纸浆纤维泡沫夹层结构具有明显更高的压缩和弯曲模量和强度。通过加入牛皮纸衬里纸加强剂进一步加强纸浆纤维泡沫芯，可以获得更高的机械性能，包括搭接剪切性能。

期刊介绍： Composites Part A: Applied Science and Manufacturing is a comprehensive journal that publishes original research papers, review articles, case studies, short communications, and letters covering various aspects of composite materials science and technology. This includes fibrous and particulate reinforcements in polymeric, metallic, and ceramic matrices, as well as 'natural' composites like wood and biological materials. The journal addresses topics such as properties, design, and manufacture of reinforcing fibers and particles, novel architectures and concepts, multifunctional composites, advancements in fabrication and processing, manufacturing science, process modeling, experimental mechanics, microstructural characterization, interfaces, prediction and measurement of mechanical, physical, and chemical behavior, and performance in service. Additionally, articles on economic and commercial aspects, design, and case studies are welcomed. All submissions undergo rigorous peer review to ensure they contribute significantly and innovatively, maintaining high standards for content and presentation. The editorial team aims to expedite the review process for prompt publication.
