摘要
以碳纤维为基础的复合材料对减少交通运输中的排放至关重要。然而,由于实验上的困难,其主要成分(即微尺寸碳纤维)的物理性质仍然鲜为人知。不过,众所周知,这种材料在离轴和在轴特性之间具有高度各向异性。在这里,我们利用 X 射线计算机断层成像技术定量探测了微米碳纤维和玄武岩纤维的电子密度和形态。碳纤维的密度随半径的变化而变化,其中心为最大值,半径一半处为最小值,而玄武岩纤维则是均匀的。在纤维尺度上对形态进行研究,以量化其与完美圆柱体的偏差,在纳米尺度上对表面纹理进行评估。分辨率约为 200 纳米。这项开创性工作将为纳米尺度的单根微米级纤维的体型或表面实验带来新的理解。
X-ray tomo-ptychography of single micrometric carbon and basalt fibres
Carbon fibre-based composite materials are essential for emissions reduction in transportation. However, the physical properties of their main component, i.e. the micro-size carbon fibres, are still poorly documented because of experimental difficulties. Such material is however known for presenting high anisotropy between off- and on-axis properties. Here we have used Ptychography X-ray Computed Tomography to probe quantitatively the bulk electronic density and the morphology of micrometric carbon and basalt fibres. The carbon fibre exhibits a density variation as function of its radius, with a maximum at its center and a minimum around half of the radius, while the basalt fibre is homogeneous. Morphology is investigated at the fibre scale to quantify its deviations from a perfect cylinder and at the nanoscale to evaluate the texture of the surface. Resolutions are around 200 nm. This pioneering work should open new understandings and bulk or surface experimentations on single micron-size fibres at the nanoscale.
