The present work is aimed at assessing the feasibility of integrating thermoplastic polypropylene nanocomposite matrices into conventional fiber-reinforced composites based on hybrid textiles that incorporate both the matrix and glass-fiber yarns, in order ...
The effect of different curing temperatures (from 20 to 40 °C) on the compressive strength and hydration of Ultra-High Performance Fibre Reinforced Concrete (UHPFRC) have been investigated between 3 and 28 days, using the loss on ignition test (LOI) and th ...
The potential of pulp fiberreinforced thermoplastics is currently not fully explored in composites. One of the main reasons is that pulp fibers are extracted for the use in papermaking and are thus not optimized for use as reinforcements in thermoplastics ...
Mechanical and fracture behaviors of wood are defined by the morphology and mechanical properties of wood fibers and their bonding medium. Parallel orientation of wood fibers makes them the most influential microstructural elements from the mechanical poin ...
A probabilistic method for the strength prediction of adhesively bonded double lap joints composed of pultruded GFRP adherends subjected to quasi-static axial tensile loading is presented. The prediction method is based on the experimentally determined mat ...
Electrical resistance in carbon-fiber reinforced polymers has been shown experimentally to be a sensitive measure of internal damage. To quantify the dependence of electrical resistance on mechanical fiber damage at the micromechanical level, a numerical e ...
Stress changes in hydrogenated phosphorous-doped fibers after Bragg grating inscription have been measured. Fibers with three different drawing tensions have been investigated. The core stress was found to increase independently of the initial stress state ...
The reinforcement potential of pulp fibres is presently not fully explored in thermoplastic composites. One of the reasons is that currently used processing methods comprise several severe thermomechanical steps inducing premature degradation of the fibres ...
The forced compression behavior of random 3D and 2D pulp fiber networks is investigated. Existing theories are found to describe well the evolution of packing stress with fiber volume fraction for the pulp networks. It was, moreover, found that the packing ...
A Green's function method (GFM) for simulating fiber damage evolution and tensile strength in fiber-reinforced composites is compared in detail to the predictions of the standard shear-lag model (SLM) widely used in the literature. The GFM extracts the in- ...
