The (brittle) behavior of concrete, although used in many fields, impedes its use some applications that require (flexible) behavior, wherefore several types fibers were utilized among them polypropylene fiber (PPF), enhances pre-crack tensile strength, toughness, ductility performance, impact resistance, flexural strength and failure mode. This paper submits a comprehensive review previous stu...

Low-pressure plasma etching of a recycled polyethylene terephthalate (PET) film is studied in comparison to virgin PET and polypropylene (PP) using capacitively coupled radio frequency (RF) reactor. Recycled polymers are distinguished by increased impurity content weakened mechanical properties, both affecting adhesion processes. Mild conditions have been selected maintain the material bulk pro...

Thermoformed products bear great potential for the application of recycled materials when using multilayer structures incorporating post-consumer recyclates. For this study, four different commercially available polypropylene recyclates are selected as possible core layers processing thermoformed with top virgin polypropylene. Tests performed on material level well product level. At level, exhi...
