    Desenvolvimento de um aplicativo na Power Plataform para gestão de qualidade assegurada em uma indústria alimentícia: Matriz QA em ação
    (2023-09-15) Silva, Rafael Aldreem Alves da; Ghislandi, Marcos Gomes; http://lattes.cnpq.br/3409757365313853; http://lattes.cnpq.br/1915012203419619
    This study highlights the development and implementation of an application on the Power Platform, using SharePoint as a database, aimed at quality management in the food industry, emphasizing the QA Matrix. Considering the complexity and regulations of the food sector, ensuring quality is essential. The application developed centralizes information, optimizes the management of QA's history, reduces the dispersion of documents and strengthens the management and control of QA's. The QA Matrix is applied in a structured manner, facilitating the identification, prioritization, and mitigation of risks. The research highlights the effectiveness of the integration between Power Platform and SharePoint, bringing benefits such as the consolidation of databases and files, refined control over trends and errors in preparation, and an improved interface compared to previous methodologies. The transition from multiple files to a single application, combined with an intuitive interface and preventive adjustments, results in time savings and greater precision in the construction of the QA Matrix. The proactive approach adopted reinforces the commitment to excellence in quality in the food industry.

    ESTUDO COMPARATIVO DAS PROPRIEDADES TÉRMICAS, MORFOLÓGICAS E MECÂNICAS DE PA E PLA NA IMPRESSÃO 3D
    (2024-11-30) Silva, Rafael Aldreem Alves da; Ghislandi, Marcos Gomes; http://lattes.cnpq.br/3409757365313853; http://lattes.cnpq.br/1915012203419619
    This study conducted a comprehensive characterization of the thermal, morphological, and mechanical properties of poly(lactic acid) (PLA) and polyamide (PA) filaments used in 3D printing, including their carbon fiber (CF) and glass fiber (GF) reinforced variants, as well as specialized versions for high-strength (PRO) and high-temperature (PAHT) applications. Using Differential Scanning Calorimetry (DSC), tensile tests, and Scanning Electron Microscopy (SEM), the thermal behavior, mechanical strength, and internal morphology of the filaments were investigated. The results indicate that PAHT CF15, reinforced with 15% carbon fiber, exhibits the best thermal and mechanical resistance, making it suitable for high-temperature applications. PA6 GF30, with 30% glass fiber, offers a good balance between stiffness and strength. In contrast, PLA White and PLA Pro materials are more suited for moderate- temperature applications. The analysis of different infill patterns (40% and 100%) reveals that the choice of configuration depends on cost-effectiveness, considering the specific application and desired strength. The study suggests that improvements in matrix-fiber adhesion could optimize the performance of the composites, particularly for PAHT CF15.
