Pure and Fibre-Hybrid Carbon Fibre and Polypropylene 3D Woven Composite Micrographs

Raw micrograph images for both a pure carbon fibre layer-to-layer 3D woven composite and a fibre-hybrid carbon fibre and polypropylene layer-to-layer 3D woven composite are presented. For the micrograph images, samples were cut from the plaque using a water jet cutter to minimise damage. Each sample was placed into a circular mould and cold-mounted with Struers Epofix. The resin and hardener were mixed at a weight ratio of 25 to 3 grams. The mixture was stirred for two minutes and then degassed for 30 minutes to remove any air bubbles. The degassed mixture was poured over the samples in the moulds and allowed to cure at room temperature for 12 hours. The samples were then removed and polished using a range of abrasive papers up to 4000 grit. The polished samples were imaged using a SmartZoom microscope with a 1.6x magnification lens.

本数据集展示了纯碳纤维层间3D编织复合材料与纤维-聚丙烯混合碳纤维层间3D编织复合材料的原始显微图像。为获取显微图像，样本采用水射流切割技术从基板上精确切割，以最大程度地减少损害。每个样本被放置于圆形模具中，并使用Struers Epofix进行低温固定。树脂与固化剂按照25比3克的质量比混合。混合物搅拌两分钟后，进行30分钟的脱气处理，以消除任何气泡。脱气后的混合物被倒入模具中的样本上，并在室温下静置12小时进行固化。固化后的样本随后被取出，并使用一系列至4000目磨料的砂纸进行抛光。抛光后的样本通过配备1.6倍放大镜头的SmartZoom显微镜进行成像。
