Influência da incorporação de negro de fumo e carbonato de cálcio micro e nanoparticulado nas propriedades reológicas, colorimétricas e mecânicas de filmes de polietileno de baixa densidade
(Universidade Federal de São Carlos, 2021-06-30)
In this work, the influence of incorporation of Carbon Black (CB) and CaCO3, both with different particle sizes, on the rheological, colorimetric and mechanical properties of LDPE films were studied. Three different types ...
Monitoramento in/on-line da malaxagem na extrusão: hidrólise e extensão de cadeia do poli(tereftalato de etileno) e fusão do polipropileno
(Universidade Federal de São Carlos, 2020-08-14)
During twin-screw extrusion, understanding and quantifying the behaviour of molten polymers under different conditions is limited by the complex configuration of the equipment. Due to this fact, real-time extrusion monitoring ...
Computational modeling of rubber multiaxial pressing applied to ceramic materials
(Universidade Federal de São Carlos, 2021-04-07)
Uniaxial and isostatic powder pressing are well known processes. However, disadvantages such as the production of heterogeneous parts or low productivity, respectively, are intrinsic drawbacks. Rubber Multiaxial Pressing ...
Desenvolvimento de vitrocerâmicos transparentes resistentes ao impacto
(Universidade Federal de São Carlos, 2021-11-11)
Transparent glass-ceramics (GCs) can replace glasses traditionally used as ballistic windows and electronic displays due to their better mechanical properties. This improvement is obtained by the crystallization of phases ...
