The application of continuous fibre reinforced plastics for components in rail vehicles opens up enormous potential for lightweight construction, especially when carbon-fibre reinforced plastics (CFRP) are used. For example, CFRP sandwich structures can be used to realize very light shell structures for car bodies or front cabins. However, these sandwich structures are usually subjected to high impact loads by flying gravel or other objects due to their exposed exterior position, which can quickly lead to critical damage in pure CFRP laminates. CG Rail GmbH in Dresden and its partners have carried out extensive theoretical and practical investigations on impact-resistant CFRP sandwich components as part of the development of the CETROVO lightweight train. The results of these investigations serve for an efficient predetermination of suitable layer structures in future projects by means of finite element simulation. [ABSTRACT FROM AUTHOR]

Polymer laminates typically make complex samples for infrared (IR) analysis, comprising multiple layers with defined thicknesses, in some cases <10 µm. When measuring extremely narrow laminate layers, the use of attenuated total reflectance (ATR) may provide improved spectra of the laminate cross-section, because ATR microscope objectives offer a greater spatial resolution than transmission because of additional magnification. This article details the preparation of polymer laminate sample cross-sections and the collection of transmission and ATR spectra of various layers. Further analysis of the laminate spectra is also explored using a multivariate curve resolution (MCR) algorithm. An example laminate sample is examined using all the tools available on a standard Fourier transform infrared (FT-IR) microscope. [ABSTRACT FROM AUTHOR]
