Última Approche experimentale du comportement d'une plaque composite sous effet d'un choc perforant ArchiMer Paris, P; Genin, D; Hamelin, P. Our purpose in this paper is to study the behaviour of composite materials reinforced by glass satin weave 8 fabric under the impact of a projectile. The first part of this paper deals with experimental tests carried out using a servo-hydraulic machine. The hydraulic ram can be programmed to impact the specimen at any desired velocity between a few tenths of a millimetre per minute and 20 m/s. In the second part, these experimental results are compared with the numerical results of bidimensional finite difference code AUTODYN. This program allows the numerical simulation of the penetration of composite plates by projectiles.

Ano: 1992 URL: http://archimer.ifremer.fr/doc/1992/acte-1045.pdf Correlation essais-calcul pour materiaux composites en application marine ArchiMer Choqueuse, Dominique; Davies, Peter; Bigourdan, Benoit. The use of finite element calculations is valuable in the design of composite structures, but few examples of correlations between measured behaviour and finite element calculations are currently available. After definition of a representative type of structure (a stiffened sandwich boat hull), and construction of a test set-up allowing the loading of such panels (uniform pressure loading of 1 m by 2 m panels), modelling was performed in four laboratories using different finite element codes. The results obtained (deflections and strains) have been correlated with test results. A satisfactory correlation is obtained for deflections (differences around 20% for the central deflection) but the correlation between measured and calculated strains is less...

Ano: 1992 URL: http://archimer.ifremer.fr/doc/1992/acte-1046.pdf Dégradation de matériaux composites dans un environment marin: Nouveaux materiaux et methodes d'essais ArchiMer Pomies, F; Carlsson, L; Choqueuse, Dominique; Davies, Peter. The change in composite material properties when these are exposed to a marine environment is of considerable importance to both designers and users of these materials. In this paper new materials are first studied, composites composed of a glass fibre reinforced thermoplastic PPS matrix. It is shown that their poor interfacial resistance to moisture ingress compromises severely the advantage of using a matrix which does not absorb moisture. In the second part of the paper the application of two non-destructive test techniques for following damage development, based on ultrasonic wave propagation and vibration (modal) analysis, are described. These are complemented by first results from a study using fracture mechanics tests to characterise delamination...

Ano: 1992 URL: http://archimer.ifremer.fr/doc/1992/acte-1064.pdf Essai de caractérisation sous pression de panneaux en composites pour structures marines ArchiMer Reichard, R. Traditional testing of FRP sandwich panels using uniaxial loading provides useful data for structural designers, but these tests do not work well for multiaxially reinforced laminates or for sandwich laminates. Sandwich laminates are generally used to increase the flexural properties of a panel. Flexural testing of sandwich beams does not address panel membrane effects, which can be significant. As a result, a number of different methods have been developed for testing panels. Experiments with multiaxial FRP sandwich panels have been conducted to evaluate the behavior of panel laminates with various fiber orientations and core materials under both static pressure loading and hydrodynamic shock loading. The test apparatus and methods are described, and the...

Ano: 1992 URL: http://archimer.ifremer.fr/doc/1992/acte-1086.pdf La qualite du controle par ultra-sons des materiaux composites utilises en construction navale ArchiMer Lehire, J; Cancre, F. Ultrasonic non-destructive testing is frequently used for composite materials. Concerning shipbuilding materials, the observation of the echograms reveals significant acoustic noise which impairs the detection of defects. The usual practice of analysing individual echograms is therefore inadequate. A method based on the intercorrelation function has therefore been developed and tested. The results should allow a classification of materials based on a criterion of the quality expected for each material.

Ano: 1992 URL: http://archimer.ifremer.fr/doc/1992/acte-1055.pdf Les essais mécaniques a la DCN, de l'eprouvette aux structures ArchiMer Hoarau, P. In order to correctly dimension surface ship hulls made of organic matrix composites, the DCN carries out different kinds of mechanical testing: Quasi-static and dynamic. Sample size varies from small scale (for material selection) to large scale (for the choice of assembling technology between deck and hull). As often as possible, the DCN performs correlation studies between its experiments and existing numerical tools, in order to improve the accuracy of computer modelling.

This communication presents a research programme concerned with the behaviour of composite materials used in marine structures, including properties, calculation methods, fire behaviour, and fabrication. Conclusions from this project will be presented in the form of recommendation cards which will help French manufacturers to obtain gains in productivity, competitiveness and quality.

Ano: 1992 URL: http://archimer.ifremer.fr/doc/1992/acte-1048.pdf Materiaux composites courants: Tenue au feu ArchiMer Croquette, Jean; Baudin, M. In the national naval composites project, several series of fire tests have been carried out on epoxy glass pipes and different structural materials commonly used in naval construction. This paper describes the materials tested and the procedures chosen to evaluate the fire reaction properties: flammability (M classification), smoke emission (F classification), and the fire resistance (IMO A 517(13)). The conclusions are given for both the testing procedures and the performance of the composite materials.

Ano: 1992 URL: http://archimer.ifremer.fr/doc/1992/acte-1047.pdf MatrigelBD, A Biocompatible Scaffold that Improves Gingival Mesenchymal Stem Cells Proliferation International Journal of Morphology Brizuela,Claudia; SaintJean,Nicole; Garchitorena,Nicolas; Rodriguez,Ismael; Inostroza,Carolina. MatrigelBD is a hydrogel scaffold with three-dimensional intercrossed networks of hydrophilic polymers with high water content. Human gingival tissue might represent a better source of MSCs, allowing these cells to be easily obtained in a relatively non-invasive way. The objective of this study was to evaluate the biocompatibility of MatrigelBD with GMSCs in vitro. Gingival connective tissue samples were obtained from healthy donors. Fresh tissue was minced and cultured during two weeks, after which cells at passage fourth were analyzed for their immune phenotype by flow cytometry. Differentiation into osteogenic, chondrogenic, and adipogenic lineages was induced and evaluated by culture staining. The "construct" was made of MatrigelBD with GMSC. To assess...

Ano: 2016 URL: http://www.scielo.cl/scielo.php?script=sci_arttext&pid=S0717-95022016000200043 Testing the effectiveness of tough resin systems for improving structural performance of joints in GRP ships. ArchiMer Norwood, L; Caulier, C. A major concern in any composite structure is its ability to resist peel and shear loading; this becomes a more difficult problem where long delays in laminating have occurred or when dissimilar materials are joined together. In the case of mine countermeasure vessels, adhesion between stiffener and hull becomes critical when the ship is subjected to underwater shock loading. In order to reduce costs and improve the hull-stiffener bond, tough resin systems based on urethane acrylates have been developed to replace the mechanical crack-stopping system currently employed. This paper describes the benefits of urethane acrylates in the frame-hull application discussing the level of improvement over the mechanical system.
