“…This is enlarging the surface area and is also giving the surface valleys which are facilitating a better bonding [22]. A thin glass fiber fabric was used to prevent the steel from contact corrosion which occurs when carbon fibers are in contact with base metals [23,24]. Figure 2 shows the stack sequence of the hybrid plate while the symbols a, b, c and d are referring to the materials shown in Table 2 while 2 mm of the plates were made of a steel plate and the other 2 mm were made from the composite.…”

This paper is dealing with the influence of processing parameters for manufacturing of steel-carbon-fiber-reinforced-plastic (CFRP) hybrid plates by using the one-shot-hybrid resin-transfer-moulding (OSH-RTM) process. A design of experiments study was carried out. The quality of the manufactured parts was quantified by the bending modulus, the apparent interlaminar shear strength (ILSS), the maximum deflection and the density of the CFRP. The following changeable processing parameters were chosen: mould temperature, resin temperature, change in mass flow and maximum injection pressure. It is shown that the mould temperature and the change in mass flow show significant impact on the flexural modulus, density and maximum deflection of the plate while there is no significant impact on the apparent ILSS. Furthermore, the interaction between the mould temperature and resin temperature is having an influence on the flexural modulus and density.

“…19 The issue has also been topical for decades in the context of the aerospace industry, 20 which has now adopted CFRPs in contemporary aircraft. In the context of automotive alloys, there was a recent study coupling CFRP to coated steel 21 revealing the galvanic corrosion behavior of a CFRP/steel couple is critically dependent on the CFRP's surface polymer layer conditions. The ongoing demand for the use of CFRP in automotive applications requires further systematic study of the galvanic corrosion between carbon fiber composites and automotive engineering materials, including a range of steels (with a range of surface treatments) and numerous Al alloys.…”

Due to increasing vehicle greenhouse gas emission regulations across the globe, the automotive industry is facing pressure to improving fuel economy. The key to achieving this is reducing vehicle mass and developing alternative energy vehicles, thereby reducing environmental impact. Lightweighting has become one of the most important aspects to consider in the design and manufacture of modern vehicles, while electric vehicles require a different approach to design and build. All the aforementioned factors have a significant impact on materials selection and usage, and corrosion is a vital consideration. In this article, we discuss and summarize some of the challenges and demands of future fuel-efficient vehicles, from the perspective of corrosion avoidance

“…Self-piercing rivets (SPRs), a type of mechanical fastener for joining sheet materials, are considered as a high potential solution for CFRP/metal joining [ 9 , 10 , 11 ]. Unlike conventional SPR specimens, the hole drilling of CFRP is required to avoid galvanic corrosion of the rivet interface between CFRP and metal [ 12 , 13 ]. In particular, pre-hole machining is regarded as essential for SPR application to high-tension steel plates (HTSP), for the purpose of enhancing the safety of motor vehicles.…”

There has been an increase in demand for the development of lightweight and high-strength materials for applications in the transportation industry. Carbon fiber reinforced polymer (CFRP) is known as one of the most promising materials owing to its high strength-to-weight ratio. To apply CFRP in the automotive industry, various machining technologies have been reported because it is difficult to machine. Among these technologies, picosecond laser beam-induced machining has attracted great interest because it provides negligible heat transfer and can avoid tool wear. In this work, we conducted and compared machining of 2.15 mm-thick thermoset and 1.85 mm-thick thermoplastic CFRPs by using a green picosecond laser. The optimized experimental conditions for drilling with a diameter of 7 mm led to a small taper angle (average ~ 3.5°). The tensile strength of the laser-drilled specimens was evaluated, and the average value was 570 MPa. Our study indicates that green picosecond laser processing should be considered as a promising option for the machining of CFRP with a small taper angle.
