26.1.2-R15 PHOSPHORUS-CONTAINING FLAME RETARDANTS IN EPOXY RESINS. EFFICIENCY AND INFLUENCE ON MATERIAL PARAMETERS

C.SCHMIDT (FRAUNHOFER LBF), K.UTALOFF, M.DÖRING

Bridged phosphorus containing compounds are efficient flame-retardants in epoxy resins. Phosphonates are able to increase the glass transition temperature of the cured resin by crosslinking. We will present the flame-retardant efficiency and will discuss the influence on material properties.

26.1.2-R16 EXPERIMENTAL INVESTIGATION OF CYCLIC AXIAL STRESS-STRAIN RESPONSE OF CFRP-CONFINED CONCRETE

E.HANTOUCHE, N.HANY (AMERICAN UNIVERSITY OF BEIRUT), M.HARAJLI

An experimental investigation was performed to evaluate the stress-strain of carbon fiber reinforced polymer confined plain concrete columns under cyclic compressive loading. The characteristics of the confined specimens were identified and existing stress-strain models were compared with the experimental results.

26.1.3-R15 FLAME RETARDING IMPROVEMENT OF NYLON 6,6 COMPOSITES WITH ZEOLITE

P.THREEPOPNATKUL (SILPAKORN UNIVERSITY), R.MUKKAYADECHOCHAI, W.JARUNAVIN, W.KHAMKHLY, C.KULSETTHANCHALEE

Effects of types and contents of zeolite were investigated on flammability of Nylon6,6. LOI of Nylon6,6 composites with zeolite-5A was higher than Nylon6,6 composites with zeolite-3A and 4A. Testing UL94 of Nylon6,6 classified V-2 type while Nylon6,6 composites with 15%wt of zeolite 3A, 4A, 5A was classified as V-0 type.

26.1.3-R16 USE OF GLASS FIBER REINFORCED POLYMER EXTERNAL REINFORCEMENT IN CONSTRUCTION AND REPAIR OF REINFORCED CONCRETE LIQUID CONTAINMENT STRUCTURES

M.PAREDES GONZÁLEZ (UNIVERSIDADE DA CORUÑA), MF.HERRADOR, IV.RAÑA, I.GONZÁLEZ

The use of external GRFP reinforcement in concrete axisymmetric liquid retaining structures is analyzed. Direct tensile tests on strengthened RC specimens, permeability tests, concrete/GFRP bonding tests and a numerical analysis have been performed.

26.1.4-R15 RESIDUAL STRENGTH OF WOUND COMPOSITE PRESSURE VESSELS SUBJECTED TO FIRE EXPOSURE

V.ALEMANY, JP.BERRO, D.HALM (ENSMA), T.ROGAUME, M.ROPITAL

The influence of an exposure to a fire on the mechanical strength of hydrogen vessels is studied. A damage model is validated by simulating the mechanical behaviour of samples subjected to fire and the residual strength of the hydrogen storage.

26.1.4-R16 STUDY OF SISAL REINFORCED CASTOR OIL POLYURETHANE COMPOSITES FOR USE AS WALL PANEL

LK.SOUSA (UNIVERSIDADE FEDERAL DE UBERLÂNDIA), LA.CASTRO MOTTA

Composites using a castor oil polyurethane matrix reinforced with sisal fiber were produced and had the mechanical properties analyzed. These composites were compared with the composites traditionally used at Brazilian market and showed great potential to use as wall panel.

26.1.5-R15 FLAMMABILITY OF ORGANOCLAY/GFRP COMPOSITES

TQ.NGUYEN (UNIVERSITY OF MELBOURNE), T.NGO, P.MENDIS, P.TRAN

26.1.5-R16 STRUT-AND-TIE MODEL FOR A REINFORCED CONCRETE WALL STRENGTHENED WITH CARBON FIBER-REINFORCED POLYMERS

S.QAZI (CIIT WAH CAMPUS), L.MICHEL, E.FERRIER

A nonlinear truss modeling approach to depict the behavior of the RC wall strengthened with CFRP subjected to a lateral load. The proposed model depicted well both the shear strength and load response behavior of the test specimen.

26.1.6-R15 REPAIRING BEHAVIOR OF WEAL GELS HAVING DANGLING CHAINS

S.ARAYACHUKIAT (JAPAN ADVANCED INSTITUTE OF SCIENCE AND TECHNOLOGY), S.NOBUKAWA, M.YAMAGUCHI

A new type of self-healing materials was developed using physical interaction by molecular entanglements. It is found that a weak gel having a lot of dangling chains shows autonomic healing even at room temperature in a relatively short time.

26.1.6-R16 A FAST AND EFFICIENT GEOMETRICAL METHOD TO OPTIMIZE LRI PROCESSES

N.MONTES (UNIVERSIDAD CEU CARDENAL HERRERA), F.SANCHEZ, A.FALCÓ, F.CHINESTA, E.CUETO et al.

This paper presents a computational strategy for Real-Time control systems based on a Level set representation as a configuration space. the level surface mesh is modified with the reference flow fronts. As a result, They are represented as a plane.

26.1.7-R15 EVALUATION OF MODE Ⅰ, Ⅱ INTERLAMINAR FRACTURE TOUGHNESS FOR A FILAMENT WOUND CARBON/EPOXY COMPOSITE UNDER LOW AND HIGH TEMPERATURE

J.IM (HANBAT NATIONAL UNIVERSITY), K.SHIN, T.HWANG

This study was conducted to evaluate the temperature effect of Mode Ⅰ, Ⅱ interlaminar fracture toughness for filament wound Carbon/Epoxy composite applied to pressure vessel. The interlaminar fracture toughness of Mode Ⅰ and II were high value in low temperature.

26.1.7-R16 DESCRIBING ELASTICITY IN CONCENTRATED SUSPENSIONS OF CNT INVOLVING AGGREGATES

M.PEREZ (ECOLE CENTRALE DE NANTES), E.ABISSET-CHAVANNE, F.CHINESTA

CNTs suspensions present different behaviours depending on their concentrations. As this concentration increases, fiber-fiber interactions occur and richer microstructures can be observed. This work establishes a micro-mechanical approach taking into account the aggregates elastic effects in CNTs concentrated suspensions.
