ABSTRACT:The oxidative stability of the carbon fiber-reinforced composite of polyimide was examined, in real time, using the evolved gas analysis techniques. Off-gas degradation products suggested the onset temperature for chain scissions to be fairly low at about 190 -220°C. Based on the off-gas products present and the trend of their release, the composite degradation mechanism appeared to be similar between 190 and 371°C, thereby marking 371°C to be the highest accelerated aging temperature for its longterm lifetime prediction. Beyond 371°C, different degradation mechanisms would apply.

“…CO 2 (670, 2300–2400 cm −1 ) was apparently detected mainly due to the cleavage of carbonyl groups of the maleimide ring, and H 2 O (3500–4000 cm −1 ) was the by-product of etherification condensation of DABPA phenolic hydroxyl groups. CH 4 (2930–2980 cm −1 ) was a decomposed product of DABPA aliphatic chains [ 43 ]. C=O (1710 cm −1 ), NO x (1373, 1509 cm −1 ), and C-N (1179 cm −1 ) were probably the fragments of the maleimide rings of BDM [ 44 ], while SO 2 (1264 cm −1 ) was the fragment of the broken PES chains [ 45 , 46 ].…”

Thermal behavior and fire reaction properties of aerial glass fiber (GF)/bismaleimide (BMI) composites were tested using thermogravimetric analysis (TGA), thermogravimetric coupled with Fourier transform infrared spectroscopy (TG-FTIR), cone calorimeter, limiting oxygen index, and smoke density chamber. The results showed that the pyrolysis process was one stage in a nitrogen atmosphere with the prominent volatile components of CO2, H2O, CH4, NOx, and SO2. The release of heat and smoke increased with the increase in heat flux, while the time required to reach hazardous conditions decreased. The limiting oxygen index decreased monotonically from 47.8% to 39.0% with increasing experimental temperature. The maximum specific optical density within 20 min in the non-flaming mode was greater than that in the flaming mode. According to the four kinds of fire hazard assessment indicators, the greater the heat flux, the higher the fire hazard, for the contribution of more decomposed components. The calculations of two indices confirmed that the smoke release in the early stage of fire was more negative under flaming mode. This work can provide a comprehensive understanding of the thermal and fire characteristics of GF/BMI composites used for aircraft.

In present time, BMI are widely used as a modifying agent in epoxy resins and developed epoxy-BMI hybrid resins and composites 2,7,8 and characterizetheir mechanical properties RESEARCH ARTICLE like tensile strength, flexibility, tensile modulus, impact strength, toughness and other many mechanical analysis4. However the brittle and high temperature resistance behavior of epoxy resins, limits their many useful mechanical and physical properties, hence their utility for high performance applications are limited 9,10 .…”

The new bismaleimide monomer N,N'-bis(maleimide)benzenesulfonamide [BMBS], homopolymer N,N'-bis(maleimide)benzenesulfonamide[HBMBS] and copolymers-N,N'-bis(maleimide)benzenesulfonamide-vinyl acetate [CBMBS-A] and N,N'-bis(maleimide)benzene sulfonamide-ethyl vinyl acetate [CBMBS-B] were formed by addition reaction followed by dehydration -cum-cyclization of 4-amino sulfonamide and maleic anhydride. Polymerization process was accompanied by AIBN-THF free radical initiator-solvent selected by trying of many initiatorsolvent system. Melting points were determined by open capillaries method and compounds structures were confirmed from FT-IR spectra (KBr) spectrophotometer. 1 H NMR spectra of all compounds were recorded, using TMS as internal reference. Antifungal activity were examined by various fungus-strain of Candida albicans, Alternaria soloni and Aspergillus niger and results were compared with Griseofulvin as standard reference anti-fungal drug.
