“…Firstly, the material was heated from room temperature (~25 °C) up to 315 °C at approximately 10 °C.min -1 , held in this temperature for 30 min under 1.2 MPa of pressure and then cooled down to room temperature. These parameters were stipulated according to the literature found on this subject 1,[3][4][5][6][7]19,20 and preliminary performed tests. In this work, three different cooling rates were applied in order to vary the final degree of crystallization, a fast rate of about 10 °C.min -1 , a slow rate of approximately 1°C.min -1 and an air cooling, obtained by leaving the press, die and laminate cool naturally in air.…”

The crystallization degree in semi-crystalline thermoplastics plays an important role in determining the final properties of structural composite material (e.g. toughness, stiffness and solvent resistance). The main purpose of this work is to study different induced degrees of crystallinity in carbon fiber (CF) reinforced polyphenylene sulfide (PPS) composites, by using three different cooling rates during hot compression molding processing (51%, 58% and 62% of crystallinity). In this study, the morphology, thermal and mechanical properties of the produced laminates were investigated and compared. The results showed an increase in the storage modulus (9.8%), Young's modulus (9.2%) and ILSS (14.2%) for the lower cooling rates. Evidences of fiber/interface improvement and crystallites nucleation on the fiber reinforcement surface were also identified.

“…In many applications, thermoplastic parts are coated with a thermosetting surface layer for decorative or protective purposes [16,17]. Frequently, thermoplastic parts are connected via thermosetting adhesives [18,19]. Furthermore, a thermoplastic can be used as a sizing agent for fibers to be embedded into an epoxy matrix [20,21].…”

“…[1][2][3][4][5][6][7][8][9] Due to these excellent virtues, the components manufactured with a mix of PPS and other materials are widely used in the construction of vehicles, electrotechnical engineering, and electronics and mechanical engineering. [9][10][11] In these fields, structural adhesives like epoxy are usually employed to bond components. 10 However, the untreated PPS, with poor surface wettability, usually exhibits a very low bonding strength.…”

Air dielectric barrier discharge (DBD) plasma was employed to treat the sanded polyphenylene sulfide (PPS) surface. The plasma-treated PPS samples were bonded with epoxy adhesive, and the adhesion strength was measured by the single lap-joint specimen test. Scanning electron microscopy (SEM), water contact angle analysis, and X-ray photoelectron spectroscopy (XPS) were applied to investigate the effect of the plasma treatment on the PPS surface property. A slight etching trace was detected after the plasma treatment according to the SEM images. XPS and water contact angle analysis indicated that the plasma treatment introduced sulfide oxides (S¼O and O¼S¼O) onto the PPS surface leading to a higher surface energy. A steady improvement of bonding shear strength was achieved with the increase of plasma treatment time or discharge power density, which was consistent with the failure mode study. According to the above analysis, the air DBD plasma treatment could effectively improve the adhesion property of PPS.
