Titre : Carbon foam tooling for aerospace composites manufacturing Type de document : texte imprimé Auteurs : Mihnea S. Anghelescu, Auteur ; M. Khairul Alam, Auteur Année de publication : 2008 Article en page(s) : p. 6-13 Note générale : Bibliogr. Langues : Américain (ame) Index. décimale : 668.4 Plastiques, vinyles Résumé : Carbon foam is now being investigated for use as a composite tooling material since it can be tailored to be a low cost, durable, light-weight material with low CTE, and has cure process compatibility with aerospace composites. These foams have received increased attention in the aerospace industry because they can now be produced with a wide range of thermo-mechanical properties, including low CTE, and higher service temperatures than polymer foam. This paper is an analytical study of the processing for a simple composite part on a carbon foam tooling. The curing of the composite part is simulated by using a combination of thermal and mechanical modeling. The curing is accompanied by development of residual stresses. The deformation due to these stresses is then simulated by the model. Note de contenu : - Component materials

Titre : Mold design and manufacturing using nanocomposite materials Type de document : texte imprimé Auteurs : Ken Han, Auteur ; Brian Rice, Auteur Année de publication : 2008 Article en page(s) : p. 20-27 Note générale : Bibliogr. Langues : Américain (ame) Index. décimale : 668.4 Plastiques, vinyles Résumé : Composite mold is usually used as a low cost tool in molding processes. The nano-composite molds have many advantages over the traditional low cost composite molds. The nano-composites with 1-inch and 2-inch thickness were made. As the properties of nano-composite materials are quite different from metals, the injection mold design and analysis were carried out based on CAE (computer aided engineer) tool and experiments at UDRI. Major issues in nano-composite mold design were listed and studied. Gate, runner, cooling channel locations and arrangements as well as the nano-composite mold mechanical and thermal performances were analyzed. Note de contenu : - Injection mold design

Titre : High temperature properties of state-change tooling materials Type de document : texte imprimé Auteurs : Brendan O'Toole, Auteur ; Shahidur Rahman, Auteur ; Julio Malpica, Auteur ; Jagadeep Thota, Auteur ; Stacy Raagas, Auteur ; George Calvert, Auteur ; Kevin Cao, Auteur ; Linda Clements, Auteur Année de publication : 2008 Article en page(s) : p. 42-52 Note générale : Bibliogr. Langues : Américain (ame) Index. décimale : 668.4 Plastiques, vinyles Résumé : A porous state-change material has been developed as part of a reconfigurable tooling system. The primary form of this material consists of hollow glass microspheres suspended in a water based blinder. The material is hardened by applying vacuum and elevated temperatures to the liquid slurry, leaving a thin binder layer between microspheres that holds them together. Mechanical and thermal characterization data for this material has been previously reported for relatively low temperature applications. There is interest in using this tooling system for the fabrication of the polymer composite structures that require processing temperatures in the range of 400°C (750°F). The material must withstand the thermal-mechanical loading experienced during the fabrication process, including the thermal cycling. Compression and flexural mechanical properties and coefficient of thermal expansion are determined at temperatures up to 400°C (750°F). Room temperature properties of the material are also determined after thermal cycling up to the same temperature. Note de contenu : - Density and porosity

Titre : Rapid prototyping and tooling techniques for pultrusion development Type de document : texte imprimé Auteurs : John J. Lesko, Auteur ; Daniel M. Peairs, Auteur ; Aixi Zhou, Auteur ; Ronald D. Moffitt, Auteur ; Bhyrav Mutnuri, Auteur ; Wei Zhang, Auteur Année de publication : 2008 Article en page(s) : p. 65-68 Note générale : Bibliogr. Langues : Américain (ame) Index. décimale : 668.4 Plastiques, vinyles Résumé : The speed of moving a composite part from concept to fabrication is a critical requirement of commercial composites design and manufacturing. Rapid prototyping (RPT) techniques such as selective laser sintering (SLS) can be used to produce parts for design assessment and evaluation from resin powders, and tooling forms from resin-coated stainless steel powders with subsequent bronze-infusion post-processing. Rapid tooling (RT) techniques, which have been used successfully in injection molding, can also be used to reduce tooling fabrication times and pultruded part development from months to days. Furthermore, rapid tooling techniques permit the construction of complex preform and die cross-sections which may be used to pultrude interlocking, fastenerless joint designs, for example. The advancement of snap joining from pultrusions accelerated through SLS and similar RPT and RT techniques presents greater strategic and cost effective opportunities for the development future constant cross section structural civilian and military systems (e.g. ISO marine compatible tactical shelters, Naval deck house structures, vehicle components).
