• Abstract

  Fiber/matrix adhesion controls the macroscopic properties and affects the damage initiation and progression in polymer matrix composites (PMC). This SPRINT proposal aims to understand the effect of micro- nano-scale cellulose interfacial coupling agents on the strength of fiber/matrix interface and the influence of the modified interface on damage mechanisms in glass fiber (GF)/carbon fib…

• Abstract

  The use of microfibrillated cellulose (MFC) as hierarchical substructure in multilayer polymer composite laminates is proposed, in which MFC will play dual roles: (i) as a toughening agent when dispersed in the epoxy resin matrix, and (ii) as an interfacial agent between the toughened polymer matrix and the continuous neat reinforcing glass fibers. The project contemplates the design, man…

• Abstract

  The improvement of composite interfaces has motivated research in different fields, with theobjective of reducing costs and processing time in addition to optimizing its physicochemicalproperties. Microfibrillated cellulose (MFC) has recently been developed as a hierarchicalstructure in the form of an interface agent between epoxy resin and fibrous reinforcements(glass and carbon) raw and…

• Abstract

  Because of their unique and advantageous properties, the use of high performance structural thermoplastic composite laminates of continuous fiber-reinforced polymer-matrix in aeronautics, aerospace, automotive, wind energy, oil & gas, and petrochemical industries is not only considered desirable but also as vital for the full development of these key areas for economic and social prosperi…

• Abstract

  In recent years there has been a great deal of scientific community focus on thermoplastic polymers exhibiting intrinsic self-healing behavior, which, after suffering damage they repair themselves as a result of macromolecular rearrangements mechanisms triggered by the apportion of energy in the damage event (e.g., impact, punching, scratching), or via an external source supplying a suffi…

• Abstract

  Continuous fiber-reinforced polymer composites are widely used in high performance and high demanding structures because of their high strength and stiffness / weight ratios, as well as their versatility on manufacturing large size and complex geometry constructions. Typically, damage monitoring of in-service polymer matrix composite structures makes use of foil strain-gage sensors, so th…

• Abstract

  In recent years there has been a strong interest in thermoplastic polymers with self-healing behavior, which after suffering mechanically-induced damage they self-repair via macromolecular rearrangements enabled by the energy generated in the damage process itself, or, alternativelly, via activation energy provided by an external source. The use of film-shaped self-regenerating polymers i…

• Abstract

  Nuclear Magnetic Resonance (NMR) provides non-invasive imaging by using the endogenous contrast of materials, regardless of their optical opacity. This technique has been widely used to ascertain physical parameters such as diffusion and flow in porous materials and biological tissues, probing length scales from nanometres to meters (Blümich et al., 2008). More recently this potential non…
