“…Composites made from a polymeric matrix and a fibrous reinforcement have been increasingly studied during the last decade due to their remarkable features such as corrosion, chemical and impact resistance, dimensional stability, design flexibility, suitable electromagnetic properties, temperature tolerance, etc. [ 11 , 12 ]. In composite applications, the low material density is of environmental interest because fuel consumption and CO 2 emissions are directly related to vehicle weight [ 8 , 13 ].…”

“…The role of the interface needs to be also taken into account in composite structure-property relationship requirements [ 8 , 10 , 11 ]. The interface is defined as the three-dimensional region surrounding reinforcement yarns, in contact with the matrix, with its own characteristics, corresponding neither to yarn properties nor to matrix ones [ 10 ].…”

Many metallic structural and non-structural parts used in the transportation industry can be replaced by textile-reinforced composites. Composites made from a polymeric matrix and fibrous reinforcement have been increasingly studied during the last decade. On the other hand, the fast development of smart textile structures seems to be a very promising solution for in situ structural health monitoring of composite parts. In order to optimize composites’ quality and their lifetime all the production steps have to be monitored in real time. Textile sensors embedded in the composite reinforcement and having the same mechanical properties as the yarns used to make the reinforcement exhibit actuating and sensing capabilities. This paper presents a new generation of textile fibrous sensors based on the conductive polymer complex poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate) developed by an original roll to roll coating method. Conductive coating for yarn treatment was defined according to the preliminary study of percolation threshold of this polymer complex. The percolation threshold determination was based on conductive dry films’ electrical properties analysis, in order to develop highly sensitive sensors. A novel laboratory equipment was designed and produced for yarn coating to ensure effective and equally distributed coating of electroconductive polymer without distortion of textile properties. The electromechanical properties of the textile fibrous sensors confirmed their suitability for in situ structural damages detection of textile reinforced thermoplastic composites in real time.

“…However, it should be emphasized here that it is very difficult to operate in a completely air‐free environment for atmospheric pressure in‐line processing; in practice, there is always a non‐negligible quantity of air/oxygen entrained to the reactor. Recognition of this operational consequence is essential, particularly when considering plasma deposition techniques that require the discharge atmosphere to be carefully adjusted . An additional problem is that plasma deposition techniques typically require steady, diffuse plasmas; reliable control of such homogeneous discharges is generally agreed to be difficult at atmospheric pressure except under very specific operating conditions and limited gas compositions.…”

This paper reflects on the future of low-temperature plasma science in relation to the manufacturing and novel uses of glass. The text summarizes the current state of the art on the major topics discussed, such as glass processing, optics and photonics, healthcare issues, building and fenestration applications. It also identifies several challenges that are driven by applications, and which are compatible with roadmaps for their respective industries. The frontiers of plasma science are discussed, for example, in relation to the use of plasmas as an active optical element in fast-response adaptive optics systems, optical metamaterials, and the development of next-generation nanolithography. Future demand for the successful implementation of plasma-based technologies in the glass, optics, and photonic industries will depend on further progress in plasma science. Hence, some needs and recommendations concerning both fundamental and applied plasma research are summarized.

“…Mechanical and chemical treatments had been usually carried out to activate the surfaces of different types of polymers to improve their adhesion strength with other materials. These methods are environmentally harmful, so recently, the attention of researchers as well as the industry sectors has dedicated to environment-friendly physical procedures such as low-pressure plasma (LPP) 2 –8 atmospheric pressure plasma (APP), 7 –13 gas-phase fluorination, 3,14 ultraviolet/ozone treatment, 15,16 flame impingement and Pyrosil ® technology, 17 –19 and corona treatment. 20 –23 This work had focused on the LPP technique.…”

“…These aforementioned techniques have shown different adhesion mechanisms, which were also dependent on the type of plastics. 1 –42 Acheriner et al 2,14 have reported that the oxyfluorination of some plastics such as polyethylene (PE), POM, polybutylene terephthalate (PBT), and polyamide 6 (PA6) resulted in an increase in their surface free energy where the polar component increased while the dispersive component decreased. Similar findings were highlighted by Acheriner 14 when performing LPP treatment.…”

The effect of surface treatment of polyoxymethylene (POM) using low-pressure plasma (LPP) on its adhesive bonding was investigated. Three different types of adhesives were used. Examinations of single lap shear, scanning electron microscopy, contact angle measurements, and energy dispersive X-ray analysis were carried out. The results showed that the adhesion strength was apparently enhanced when treating surfaces by LPP using argon or oxygen plasma which increased with the treatment time. This increase was also dependent on the adhesive type. Moreover, glass fiber–reinforced POM showed better adhesion strength compared to that of unreinforced POM. An increase in the surface free energy exceeding 50 mN/m was observed after 600-s treatment time compared to untreated samples (39 mN/m), where the increase in polar component was more predominant. Surface topography observations showed a significant increase in the surface roughness with increasing the treatment time, mainly when using oxygen plasma. Finally, an increase in polarity and wettability due to changes in the chemical composition of the surface was also reported.
