EFFECT OF MECHANICAL ALLOYING ON THE PROPERTIES OF AA6005A/TIB MMC
Victoria Utrilla (Universidad Rey Juan Carlos) N. Abuwarda (Universidad Rey Juan Carlos) M. Dolores Escalera (Universidad Rey Juan Carlos) Enrique Otero (Universidad Rey Juan Carlos) M. Dolores López (Universidad Rey Juan Carlos)
An A6005 aluminium alloy composite reinforced with 5% titanium boride particles have been produced by P/M processing. After 8 hours of mechanical alloying, the best size distribution and good mechanical properties were obtained.
EFFECTS OF HIGH TEMPERATURES ON ALUMINA CERAMIC FIBERS
Teresa Go (RWTH Aachen University) Davide Pico (RWTH Aachen Univeristy) Alexander Lüking (RWTH Aachen University) Thomas Gries (RWTH Aachen University) Gunnar Seide (RWTH Aachen University)
Commercial oxide ceramic fibers are exposed to different high temperatures (up to 1000 °C). After that, the structure is detected with wide angle x-ray diffraction.
MECHANICAL CHARACTERIZATION AND DAMAGE EVOLUTION OF A CU-SIC – INTERPENETRATING METAL MATRIX COMPOSITE MANUFACTURED BY A SQUEEZE-CAST INFILTRATION METHOD
Andreas Reeb (Karlsruhe Institute of Technology) Alexander Wanner (Karlsruhe Institute of Technology) Kay Weidenmann (Karlsruhe Institute of Technology)
A first mechanical characterization of a Cu/SiC-composite with interpenetrating network structure manufactured by high temperature squeeze casting of SiC- preforms was performed by means of Ultrasonic Phase Spectropy and in situ compression tests.

For cryogenic application, M40-level braiding fabric/epoxy composites were prepared via a RTM process. The mechanical properties of M40-level braiding fabric/epoxy composite at 80℃, RT and -196℃ were examined. The effects of cryogenic temperature on the mechanical properties of the composite were studied.
THE CRYSTALLINITY DEGREE INFLUENCE ON THE WEATHER RESISTANCE OF CF/PPS COMPOSITES
Natassia Batista (UNESP) Mirabel Rezende (UNIFESP) Edson Botelho (UNESP)
The influence of the polymer crystalliny on the weather resistance of CF/PPS composites exposed to hygrothermal, salt spray and UV radiation chambers were evaluated. The weathering showed to affect the crystallinity and mechanical properties.
NON-LINEAR RESPONSE OF ENVIRONMENTALLY AGED POLYMER COMPOSITES: A PHYSICOCHEMICAL AND MECHANICAL STUDY
Sotirios Grammatikos (Chalmers University of Technology) Mark Evernden (University of Bath) Richard Ball (University of Bath)
In this paper, the anomalous behaviour of polymer composites subjected to hygrothermal aging is discussed in reference to the results of a characterization study on polyester matrix fibre reinforced polymer (FRP) composites.
THERMAL PERFORMANCE EVALUATION OF ENERGY EFFICIENT PARAFFINIC PCMS/EXPANDED VERMICULITE AND PERLITE COMPOSITES FOR ENERGY SAVING
Su-Gwang Jeong (Soongsil University) Seong Jin Chang (Soongsil University) Seunghwan Wi (Soongsil University) Yujin Kang (Soongsil University) Sumin Kim (Soongsil University)
This paper deals with the preparation, characterization, thermal properties and thermal reliability of form-stable composite phase change materials (PCMs), composed of n-octadecane, expanded vermiculite, and perlite for thermal energy storage.
LONG-TERM THERMAL STABILITIES OF POLYIMIDE RESIN TRIA-X AND CARBON FIBER/TRIA-X COMPOSITE MATERIAL

Toshio Ogasawara (Tokyo University of Agriculture and Technology) Takuya Aoki (Japan Aerospace Exploration Agency)
Long-term thermal stability of polyimide resin “TriA-X” and carbon fiber reinforced TriA-X was evaluated. Although the weight loss of the resin at 270°C was significant because of oxidation, the composite material maintained compression strength.
FIRE RETARDANT ZEIN-BASED MATERIALS
