Abstract Composite materials undergo intricate damage processes, which are accentuated when these materials are exposed to impact loading conditions. In this context, this work aims to study the behavior of fiber reinforced polymer composites submitted to high strain rate in compression. A composite laminate plate was obtained using a plain weave carbon fiber fabric and an epoxy resin as matrix. The Split Hopkinson Pressure Bar (SHPB) technique was used to apply compressive loads at three differ...

Abstract After the advances of microscopic techniques, the literature shows an increasing number of fractographic studies of fiber reinforced polymer composites. However, the fractographic aspects of compressive failures remain slightly explored and poorly enlightened. In this context, the purpose of this work is to present some of the main mechanisms responsible for the fracture energy absorption in the case of fiber reinforced polymer composites submitted to compressive loads. To do so, this s...

Abstract The fractographic aspects of compression failures remain inadequately explored, mainly due to the damages that the compressive load promotes on the fracture surfaces, which difficult the identification of fracture aspects. In addition, despite the large quantity of studies on the literature, there is no consensus concerning the existing compressive failure modes. Aiming to contribute in this research field, this paper has the objective of proposing a novel classification for the compres...

This study aims to contribute to sustainability by proposing the reuse of composite prepreg scrap as an added value from discards. The research evaluates the microstructure and mechanical properties of laminates processed by the reuse of uncured carbon fibre/F155-epoxy resin prepreg scraps, waste from the ply cutting area of an aeronautical industry. The composite scraps were used as collected and were randomly positioned to produce laminates to be cured at an autoclave. The mechanical character...

Abstract This paper is part of a series of fractographic studies on fiber-reinforced polymer composites submitted to compression, which attempts to fill the gap in the composite failure analysis. Here, the effect of the hygrothermal conditioning is assessed for composite laminates manufactured from a carbon fiber/epoxy resin prepregs, which used plain weave fiber arrangement. The laminate was trimmed into compression test specimens, according to the ASTM D3410 standard. After the test, the aspec...

The increasing use of composite in the aircraft industry has raised the interest for a better understanding of the failure process in these materials, which can be also influenced by the manufacturing process of the laminate. Some materials used in vacuum assisted resin transfer molding process have been studied in the open literature but very few data have been published for resin transfer molding-6 epoxy based laminates, in particular studies showing the influence of the temperature on the int...

The accelerated aging effects on mechanical properties of carbon fiber-reinforced polyetherketoneketone (PEKK) thermoplastic composites are reported. Ultraviolet (UV) radiation and moisture absorption may induce property changes that weaken the polymeric matrix and/or deteriorate the matrix fiber interface by debonding or microcracking. The aim of the present work is to correlate the influence of the accelerated aging effects on compression and shear properties of carbon fiber-reinforced PEKK th...
