Multifunctional Structural Electrolyte with Glass FiberReinforced Polyvinyl Alc...
Niazi, M; Paiva, D; Danzi, F; Lopes, T; Mendes, A; Camanho, PP<jats:p>A novel multifunctional structural electrolyte is developed using plainweave glass fiber reinforced with a composite polymer matrix for loadbearing energystorage applications such as structural batteries. The composite matrix comprises polyvinyl alcohol (PVA) blended with epoxy, LiTFSI salt, and Al<jats:sub>2</jats:sub>O<jats:sub>3</jats:sub> at optimized ratios. A set of techniques is used to evaluate ...
Effect of the level of anisotropy on the macroscopic failure of notched thin-pl...
Mitrou, A; Arteiro, A; Reinoso, J; Camanho, PPThis work presents a detailed experimental study conducted for a range of different lay-ups using thin-ply carbon fiber reinforced polymer (CFRP) laminates. The selection of the laminates was performed relying on their level of anisotropy. The laminates vary from a quasi-isotropic (QI) laminate, which is weakly anisotropic, to a cross-ply (CP) laminate, which is strongly anisotropic. The laminates were tested i...
Micro-mechanical analysis of composite materials using Phase-Field models of br...
Macías, J; Arteiro, A; Otero, F; Camanho, PP; Reinoso, JFailure in fiber-reinforced composites is a complex phenomenon where different damage mechanisms interact and evolve through various scales. Micro-mechanical analysis using the finite element method has become an important alternative to study such failure phenomena and their interactions, by modeling explicitly the fiber, matrix, and fiber-matrix interface. In this work, the predictive capabilities of the fini...
Modeling fracture of multidirectional thin-ply laminates using an anisotropic p...
Mitrou, A; Arteiro, A; Reinoso, J; Camanho, PPAn equivalent single layer approach to model fracture events of multidirectional balanced thin-ply laminates via the use of the Phase Field method is explored. The inherent anisotropic nature of a multidirectional laminate is taken into account through the use of a structural tensor, defined from scaled directional vectors, which can account for the variation in fracture toughness of the laminates in varying di...
