Titre : Optical NDI methods for composite structures Type de document : texte imprimé Auteurs : R. B. Heslehurst, Auteur Année de publication : 2007 Article en page(s) : p. 7-14 Note générale : Bibliogr. Langues : Américain (ame) Index. décimale : 668.4 Plastiques, vinyles Résumé : The application of composite materials into high load bearing structures has required a better understanding of the impact non-conformities, defects and damage has on the structure integrity. Traditional NDI methods are only really successful in identifying the existence of the non-conformity or damage. Traditional NDI methods do not provide any assessment of the effect of the non-conformity on the structural performance of the composite structure. The optical NDI methods allow for non-contact, full-field interrogation of the component to visually reveal the impact on composite structural integrity of the non-conformity under representative load states. In this paper the five principal optical NDI methods are briefly reviewed and, using holographic interferometry, illustrated against the typical in-service damage found in composite structures. Each NDI methods is further compared to show there relative range of capabilities against a variety pf composite defects. Note de contenu : - Aim

Titre : Water dispersible core technology for the manufacturing of hollow-structure parts Type de document : texte imprimé Auteurs : Li Ma, Auteur ; Peter Mitschang, Auteur ; Amol Ogale, Auteur ; Alois K. Schlard, Auteur Année de publication : 2007 Article en page(s) : p. 24-33 Note générale : Bibliogr. Langues : Américain (ame) Index. décimale : 668.4 Plastiques, vinyles Résumé : For manufacturing parts of composite material, metal molds are normally used. However, metal molds are very heavy and expensive. In addition, for some complex geometry parts, such as hollow structures, metal cores are not suitable. In this situation, water dispersible cores can be well utilized instead of metal. In this paper the properties of water dispersible tooling material have been studied, including physical properties and mechanical properties. The washout capability and process challenges have been analyzed. Moreover, a hollow-structure prototype and a T-shape beam, made of carbon fiber reinforced polymer (CFRP), are manufactured by using Vacuum-Assisted Resin Transfer Molding (VARTM) process. Furthermore, mean roughness of the prototype was investigated. Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=23357

Titre : Test methods for thin carbon-carbon composite laminates Type de document : texte imprimé Auteurs : Erin C. Dreyer, Auteur ; Michael Rooney, Auteur Année de publication : 2007 Article en page(s) : p. 54-60 Note générale : Bibliogr. Langues : Américain (ame) Index. décimale : 668.4 Plastiques, vinyles Résumé : The Solar Probe spacecraft, currently under development by the Johns Hopkins University Applied Physics Laboratory (JHU/APL), will include a large 2.7m diameter by 5.1m long carbon-carbon (C/C) conical Thermal Protection System (TPS) which protects the spacecraft bus and instruments during the solar encounter. Operational temperatures of up to 1600°C along with system thermal, mass, ans stiffness requirements dictate the the TPS structure be fabricated from a high modulus C/C composite material. A development program was conducted by JHU/APL to measure the physical and mechanical properties of candidate C/C do not exist, American Society for Testing and Materials (ASTM) methods for advanced ceramics, plastics and composite materials have guided successful testing of similar but thicker C/C materials. Since the carbonization process in thickness dependant, it was critical that test coupons be of the same thickness as those of the actual structure. Special test configurations had to be developed to properly measure the properties of these thin laminates. Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=23409
