Abstract:
Cyanate ester thermosetting resins are a novel family of materials for high technology and aerospace applications. The high glass transition temperatures available from cured cyanate ester networks and subsequently, their resistances to corrosive materials make these resins attractive for harsh environmental applications. These features of cyanate ester resins presented a threefold opportunity for investigation, namely: 1) establish a characterization technique for the long term mechanical properties of the cured resins, 2) develop a method for determining the effect of physical and chemical

The objective of this investigation was to characterize two cyanate ester resins and a eight harness satin (8HS) graphite fabric for use in resin film infusion (RFI) processing. Two cyanate ester resin systems were characterized to determine their cure-kinetics, and viscosities during cure. A 8HS graphite fabric was tested in compaction and through the thickness permeability. A one-dimensional, through the thickness, flow and cure computer simulation was run. <p> The resin cure-kinetics models predicted the curing behavior of the resins as functions of time, temperature, and degree of cu

碩士<br>國立中央大學<br>化學工程研究所<br>87<br>Abstract Epoxy/PPO blends were cured with multifunctional cyanate ester resin . The effects of PPO content on cure behavior and thermal stability in the cyanate ester cured epoxy were investigated with FTIR,NMR and TMA . Cure reaction in the epoxy/PPO blends is faster than that of the neat epoxy system . FTIR and NMR analysis reveal that the functional group reactions are accelerated by adding PPO and indicate that several coreactions occured , such as cyanate-hydroxyl addition , epoxy-cyanate addition and epoxy-amine addition . This may be caused by

Abstract:
Several problems must be solved in the construction, design, and operation of a nuclear fusion reactor. One of the chief problems in the manufacture of high-powered copper/polymer composite magnets is the difficulty to precisely control the fiber volume fraction. In this thesis, the effect of variations in fiber volume fraction on thermal stresses in copper/cyanate ester composite cylinders is investigated. The cylinder is a composite that uses copper wires that run longitudinally in a cyanate ester resin specifically developed by Composite Technology Development, Inc. This composite cylinde

Σκοπός της παρούσας πτυχιακής εργασίας ήταν η μελέτη της περιβαλλοντικής γήρανσης ινωδών συνθέτων υλικών με κυανεστερική μήτρα σε ακραίες θερμοοξειδωτικές ή/και υγροθερμικές συνθήκες. Επίσης, ο θερμομηχανικός χαρακτηρισμός και η αρχική μελέτη των μηχανισμών υποβάθμισης. Για το σκοπό αυτό παρασκευάστηκαν πέντε τύποι πολύστρωτων πλακών οι τρείς εκ των οποίων έφεραν ως ενίσχυση οχτώ στρώσεις προεμποτισμένου πανιού ινών γυαλιού (GFRPs) τριών διαφορετικών κυανεστερικών μητρών (PN901-G201-45{GRT},HTM143,MTM110) και πλέξης 2*2 twill.

Abstract:
Das dreistufige Flüssigsilicierverfahren (LSI) stellt eine Methode dar, siliciumcarbidbasierte faserverstärkte Keramiken herzustellen. Ausgangspunkt ist ein faserverstärkter Kunststoff, der über Pyrolyse (Konvertierung des Matrixpolymers in Kohlenstoff) und Silicierung (Siliciuminfiltration und Reaktion zu Siliciumcarbid) keramisiert wird. In der vorliegenden Arbeit werden die Matrix mittels der verwendeten Matrixpolymere (Matrixdesign) und das Faser/Matrix-Interface durch das Aufbringen von Faserbeschichtungen (Interfacedesign) definiert gestaltet. Die in der Arbeit eingesetzten Matrixpolymer
