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":"41 1","pages":""},"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}

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. This research offers an effective control strategy and research approach to enhance the accuracy of temperature control during the CF-PP induction heating process, contributing to improved outcomes in the field.","PeriodicalId":17446,"journal":{"name":"Journal of Thermoplastic Composite Materials","volume":"42 1","pages":""},"PeriodicalIF":3.3,"publicationDate":"2024-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141937562","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}

For this purpose, the response surface method (RSM) and desirability function technique (DFT) are applied to find the optimal values of the effective parameters of CNT content, printing speed and nozzle temperature.

The results of DSC and TGA analyses indicated that the addition of CNT into PLA enhanced the thermal stability of PLA/CNT composite.

The review highlights SLA-based 3D printing’s better ability to optimize material compositions, printing procedures, and post-processing methods to improve material characteristics. 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. Since it integrates the latest discoveries with technological developments, this study may help guide future research and promote innovation in the sector.

Consequently, the successful combination of refill FSSW and riveting resulted in a flared trumpet-shaped rivet, expanding the diameter of its tip significantly. Tensile shear tests exhibited both the stirred zone induced by refill FSSW and the flared rivet affected the fracture behavior. The cross-sectional observations revealed the existence of cracks at the boundary between the stirred zone and base material during tensile shear tests. Furthermore, a unique arrangement of the fiber caused by the stirring action was identified by observing the fracture surface using scanning electron microscopy.

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.

Chitosan and Chi-Gly solutions prepared via glyoxal crosslinking were incorporated into recycled pulp suspensions at varying dosages. Laboratory handsheets were fabricated, and their properties were systematically evaluated through mechanical testing, morphological analysis, wettability measurements, and antibacterial assays. The results demonstrated significant improvements in the tensile index, burst index, and bending resistance for the chitosan and Chi-Gly treated papers, with the Chi-Gly exhibiting superior reinforcement. Notably, the Chi-Gly treated paper exhibited a higher wet tensile index and lower water absorption capacity than the control. SEM analysis revealed a denser, more cohesive fiber network facilitated by chitosan and Chi-Gly, aiding the reinforcement. The treated papers exhibited reduced hydrophobicity and pronounced antibacterial activity against E. coli (a gram-negative bacterium) and S. aureus (a gram-positive bacterium), with the Chi-Gly treatment outperforming chitosan.
