Les polibenzoxazines son una classe relativament nova de resines fenòliques termoestables que posseeixen interessants propietats per a la indústria electrònica, automobilística, aerospacial i d’adhesius. Les seves possibilitats superen a les dels sistemes fenòlics clàssics, novolaques i resols, principalment en que no necessiten catalitzador per portar a terme el seu curat i no alliberen volàtils de condensació durant el mateix.

Abstract:
<p> Carbon-fiber composites are increasingly employed in the Aerospace and Automotive industries owing to their lightweight and excellent mechanical properties. However, this class of material, when subjected to out-of-plane loads, is often susceptible to an internal damage in the form of delamination that can severely reduce its load bearing capacity. Several toughening methods including the implementation of thermoplastic materials are used to increase the damage tolerance of the polymer-matrix composites. In particular, non-woven thermoplastic veils, when used as interleaving materials betw

Abstract:
<p> New applications of polymers and their composites are arising and replacing traditional materials in the sectors of aerospace, automotive, and civil industries. Polymers and their composites are susceptible to oxidative degradation at high temperatures, especially when approaching but not quite reaching the glass transition temperature (<i>T<sub>g</sub></i>). Although the carbon fibers in these composites are stable at such temperatures, the matrix and especially the fiber-matrix interface can undergo degradation that affects the physical, chemical, and mechanical properties of the structu

Abstract:
<p>Understanding the curing kinetics of a thermoset resin has a significant importance in developing and optimizing curing cycles in various industrial manufacturing processes. This can assist in improving the quality of final product and minimizing the manufacturing-associated costs. One approach towards developing such an understanding is to formulate kinetic models that can be used to optimize curing time and temperature to reach a full cure state or to determine time to apply pressure in an autoclave process.

In the study, DP was modified into cyanate ester, DPCY, and blended with bifunctional benzoxazine, 4,4’-diaminodiphenyl ether-based benzoxazine(ODABz). The two resins co-reacted when being cured. The dielectric constants were decreased by adding DPCY in to the thermosets. The resulting materials achieved great thermal properties, thermal stability, and dielectric properties.

It was cured by two procedures. First, the benzoxazine was photo-cured by UV light, followed by the thermo-curing. The structures of monomer (1) and (2), including photosensitive group, were monitored by 1H NMR, 13C NMR and FTIR analysis. The monomer (2) could produce two different kinds of structures after thermo-curing and photo-curing. The monomer (2) has the great difference in mechanical, dimensional stability, a

In many literatures, we learned that the properties of polybenzoxazines can be tuned by inducing different functional groups into the molecular structure of benzoxazine. In this thesis, a new benzoxazine monomer, uracil based benzoxazine (UBZ), possessing multiple hydrogen bonding interaction sites was successfully prepared. By inducing UBZ to BZ, the s

The monomer was characterized by 1H NMR, Elemental Analysis (EA) and Fourier Transform Infrared (FTIR). DSC analysis of the monomer shows two peaks, one is an endothermic peak at 144 °C which corresponds to the melting point of the monomer and an exothermal peak at 240 °C which corresponds to the ring opening process of the benzoxazine ring.
