A complete database of the mechanical properties an epoxy polymer reinforced with uni-weave carbon fibre non-crimp fabric (NCF) is established. In-plane and through-the-thickness tests were performed on unidirectional laminates under normal loading shear loading. The response cyclic was also measured. material has been characterised in terms stiffness, strength, failure features for different cases. critical energy release rates associated modes measured from interlaminar translaminar...
The present work is dedicated to the experimental and numerical study of buckling behaviour under pure compression carbon–epoxy adhesively-bonded scarf repairs, with angles varying from 2 45°. results were used validate a methodology using Finite Element Method mixed-mode cohesive damage model implemented in ABAQUS® software. adhesive layer was simulated elements trapezoidal traction–separation laws modes I II account for ductility used. determined Double Cantilever Beam End-Notched Flexure...
A safe design of composite tanks for liquid hydrogen is one the strongest challenges in coming years. This paper describes an approach to characterize influence cryogenic temperature on mechanical properties a thin-ply carbon/epoxy material manufactured by wet filament winding. The aim obtain required lightweight suitable layup future use as cylindrical tube linerless tank storage at and interior pressure. methodology presented determining ply input parameters analytical models describing...
In this work, a repair technique with adhesively bonded carbon-epoxy patches is proposed for wood members damaged by horizontal shear and under bending loads. This damage characterized crack growth near the neutral plane of beam, normally originating from checks shakes. The consists on vertical side faces beam at cracked region to block sliding between arms. An experimental numerical parametric analysis was performed patch length. used finite element method (FEM) cohesive zone models (CZMs),...
The behavior of a repaired sandwich beam subjected to four-point bending is investigated numerically using the ABAQUS ® software and specially developed interface elements including cohesive mixed-mode damage model based on indirect use fracture mechanics. two major repair configurations for structures, namely overlap scarf repair, are studied. elements, placed at middle adhesive, parent laminate/adhesive adhesive/patch interfaces, allow obtain stress distributions these locations as well...
The interlaminar fracture toughness in pure mode II (GIIc) of a Carbon-Fibre Reinforced Plastic (CFRP) composite is characterized experimentally and numerically this work, using the End-Notched Flexure (ENF) characterization test. value GIIc was extracted by new data reduction scheme avoiding crack length measurement, named Compliance-Based Beam Method (CBBM). This method eliminates measurement errors, which can be non-negligible, reflect on accuracy energy calculations. Moreover, it...
This work reports on the experimental and numerical study of bending behaviour two-dimensional adhesively-bonded scarf repairs carbon-epoxy laminates, bonded with ductile adhesive Araldite 2015®. Scarf angles varying from 2 to 45º were tested. The performed was used validate a Finite Element analysis using ABAQUS® methodology developed by authors predict strength assemblies. consists replacing layer cohesive elements, including mixed-mode criteria deal usually observed in structures....
