多孔材料具有多种功能，包括轻质承重, 影响保护, 能量吸收和隔热或隔音. 它们有广泛的应用，如航空航天和运输结构, 保护镶板, 货物包装, 和绝缘.
The properties of porous materials are dependent on their composition and the detailed geometry of the porous architecture.
具有随机结构的泡沫可以通过化学或物理吹制产生, 或者通过加入空心填充物来产生句法泡沫. 更多的 controlled and ordered architectures can be produced using additive manufacturing (AM) techniques to control the locations where material is deposited. The complexity of these porous architectures makes identification and prediction of properties difficult. 尽管AM架构有所改进, 由于泡沫结构的随机性，泡沫仍然容易产生缺陷.
X-ray computed tomography (XCT) is a powerful tool that enables volumetric imaging and can identify porous materials' architecture. 当与建模结合使用时, volumetric imaging from XCT enables predictions of functionally relevant material properties. High resolution XCT imaging produces digital models of porous geometries that can be analysed through finite element analysis to predict properties and behaviour. 然而, 这些高保真的图像和预测是耗时的, 昂贵的, 对于高密度的材料和大的零件来说并不总是可能的, 这两种情况都会导致高x射线衰减和低对比度.
- 开发分析方法，预测材料的性能和行为，如机械, 热, 和声学
The goal will be to enable these predictions using low resolution XCT images that can be obtained rapidly for larger parts or denser materials. 您将利用增材制造的设施和专业知识(AM), 机械测试, 表征和pt真人电子的μ -VIS x射线成像中心.
You'll work in collaboration with a UK government defence organisation as a partner and sponsor of the project. You will have the opportunity to support and assess materials that are being developed for use in state-of-the-art defence systems where a broad range of environments will be encountered. There will be opportunities for placement within the sponsor organisation and potential for future employment.
