“…Hybridization will more and more be extended to the field of smart structures and material‐integrated intelligent systems, addressing markets beyond the already deeply investigated aerospace or wind energy plant structural health monitoring and using AM as well as other manufacturing processes like metal casting (see Figure f) as vehicle . A specific motivation for this latter point may be found in the trend toward autonomous driving.…”

The present text introduces a Special Section of Advanced Engineering Materials linked to the symposium Advanced Materials for Transport Applications organized by the authors within the framework of the EUROMAT 2017 conference. It introduces the contributions that make up this Special Section, and takes the fact that a majority of them is related to the broader topic of hybrid materials and structures as a motivation for a short overview of this exciting area of research.

“…The "smart" woven fabric is then handled as a common woven fabric and integrated in a standard CFRP process. A second example is a resistive structure printed on an aluminum sheet [8], as shown in Figure 4. The sensor can be used as either a strain gauge or a thermoresistive temperature sensor.…”

Abstract:A new and innovative approach is presented to integrate sensors in materials and set up "smart materials". Semi-finished parts are functionalized by printed sensors and printed interconnects. These functionalized parts are then further processed to components. This is a new and simple approach to integrate sensors in a material. Two examples of printed sensors and the process of integration are presented. One is a printed sensor on carbon weaves, integrated in carbon fiber reinforced plastic. The other one is a sensor structure printed on an aluminum sheet and integrated during high pressure die casting. Besides the benefits of this technological approach, challenges are focused in the paper as well.

“…Integrating sensors directly into car parts during manufacturing could yield highly precise data of the actual state of the car's main structural elements, and in particular of safety-relevant chassis components [2]. This would allow to sense directly at the point of origin of potential damage, deep inside the metal part [3] [4]. However, the harsh processing conditions, which, depending on casting process and material, entail exposure to high temperatures and mechanical loads.…”

Recent developments like autonomous driving have increased the interest of the automotive industry in structural health and condition monitoring of safety-relevant components often manufactured via High or Low Pressure Die Casting (HPDC, LPDC). Specifically the latter process is important in this field as the improved quality of castings produced facilitates T6 heat treatments aimed at optimizing mechanical performance of such components. The specific challenge associated with this approach is that it produces critical thermal loads which may compromise the characteristics of the integrated sensor. The present study shows the results obtained by LPDC on thick film sensor systems prepared by means of screen printing on aluminum substrates. The response of the sensor systems to the thermal loads associated with the casting process is evaluated in casting experiments, with temperatures reached during casting checked by means of thermocouples attached to the inserts. The focus is on the influence on general properties of the piezoresistive sensors as well as on their response to thermal and mechanical stimuli. The results show that in contrast to HPDC, in the case of LPDC, the former provides stimuli for thermally induced processes which can compromise sensor layers. The respective trends have been studied via resistance measurements on samples subjected to repeated firing cycles and actual casting experiments.
