Samples were fully immersed in the mixture of GW (20:80) at 50°C, 70°C and 90°C for up to 80 days and periodically weighted. Results gathered revealed the occurrence of substantial changes especially for PA6 samples aged at 90°C. The long term ageing leads to the formation of ester species due to thermo-oxidation as pointed out by Infrared spectroscopy analysis. Moreover, dynamic mechanical analysis measurements showed that glycol water acted as an effective plasticizer in lowering the Tg of the polyamide 6. This plasticizer effect was confirmed by the gain of ductility at early stage of ageing for both materials (PA6 and PA6GF30). Nevertheless, after 80 days of ageing the effect of glycol water ageing is no longer physical in nature and an overall loss of mechanical properties was noticed. Indeed, an embrittlement of PA6 was measured that can be attributed to a decrease of the level of entanglements within the polymer. Nevertheless, for PA6GF30 material, the loss of strength and stiffness was the result of the interfacial debonding between the fibers and the matrix.","PeriodicalId":17446,"journal":{"name":"Journal of Thermoplastic Composite Materials","volume":null,"pages":null},"PeriodicalIF":3.3,"publicationDate":"2024-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142189649","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Increase in use of polymer has led to waste problems. From an environmental point of view, recycling (reprocessing) of polymers is one of the viable solutions to diminish waste issues. Thus, in this work, the effect of reprocessing for aged glass fiber reinforced polycarbonate/acrylonitrile-butadiene-styrene (PC/ABS) composites having different glass fiber content was determined on the mechanical properties (tensile, impact, flexural), melt flow index and morphology. Virgin glass fiber reinforced PC/ABS specimens were exposed to two environments, namely artificial accelerated ageing in a QUV chamber for up to 336 h and natural ageing in Gebze (Turkey) for up to 1 year between January 2018 and January 2019 to determine the influence of a long-term outdoor exposure on the properties. After these ageing steps, naturally and UV aged specimens were ground and the ground specimens were mixed with virgin glass fiber reinforced PC/ABS at ratios of 25%, 50% and 75% by weight. The mixed materials were re-molded to fabricate test specimens and then characterized. In brief, in current research, the mechanical, rheological, and morphological properties of virgin, aged in outdoors for 12 months, aged in UV chamber for 336 h and blends of virgin-aged glass fiber reinforced PC/ABS composites were studied. Because there is no research regarding natural and UV ageing of PC/ABS having different glass fiber content, this study represents an important contribution to determining behavior of these composites after ageing. From experimental study, in general, it was found that mechanical properties decreased with natural and UV ageing, but some retention in properties could be achieved with the incorporation of pure polymer.","PeriodicalId":17446,"journal":{"name":"Journal of Thermoplastic Composite Materials","volume":null,"pages":null},"PeriodicalIF":3.6,"publicationDate":"2024-08-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141925186","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper begins by constructing a finite element microscopic model for induction heating that incorporates the actual fiber structure and matrix. It systematically analyzes the heating mechanism, temperature field distribution, and surface temperature hysteresis of CF-PP with different fiber weave structures during the heating process. Based on the observed temperature distribution and variation patterns during material heating, an improved particle swarm Fuzzy PID control method is proposed, which effectively reduces temperature overshoot and enhances the system’s resistance to disturbances. Experimental validation demonstrates the effectiveness of this algorithm for controlling the temperature of CF-PP plates during the induction heating process.

Photosensitive materials and shrinkage-induced internal tensions seems to be its major constraint. Additionally, SLS 3D printing has improved composite materials' electrical, mechanical, and thermal properties. It has drawbacks including permeable structures and internal tensions. In FDM 3D printing, mechanical and electrical qualities are improved for piezoelectric sensor manufacture. Warping and nozzle blockage require additional study. DIW’s versatility in constructing complicated structures with increased features for energy harvesting and sensor development is also mentioned. We identify ink development and printer nozzle clogging issues. The review concludes that inkjet printing can provide a variety of materials for flexible electronics.

This work examines the effects of varying percentages of CdS spheres on the structural characteristics, mechanical properties, surface/volume energy loss functions, dielectric constants, and linear/non-linear optical properties of PVB nanocomposite films. The findings confirmed the successful synthesis of sphere-like CdS with a cubic structural phase. The stress-strain curves of PVB and its composites with nano CdS spheres were examined. The PVB has a direct/indirect energy gap of 5.1 eV (4.1 eV). With a CdS doping level of 2% and 4%, the values correspondingly decreased to 4.76 eV (3.36 eV) and 4.49 eV (2.45 eV). The E<jats:sub>U</jats:sub> values for PVB, PVB-2 wt.% CdS, and PVB-4 wt.% CdS nanocomposite are 15.3, 11.2, and 14.1 meV, respectively. CdS nanospheres decreased the volume and surface energy losses (VELF &amp; SELF) of PVB films. The research demonstrates that the mechanical properties and optical parameters of PVB/CdS nanocomposite films positively correlate with the concentration of CdS nanospheres.
