The relationship between the imide structures and morphology are discussed in order to develop heat resistant polyimides having excellent processability toughness. Addition-type oligomers consisting of asymmetric 2,3,3′,4′-biphenyltetracarboxylic dianhydride (a-BPDA) 3,4′-oxydianiline (3,4′-ODA) and/or 4,4′-oxydianiline (4,4′-ODA) with 4-phenylethynyl phthalic anhydride (PEPA) were synthesized characterized. derived from 3,4′-ODA; 4,4′-ODA (50:50) comonomer molecular weights 5240 g mol −1...
Irradiation of phenanthrene in the presence various amines and carbon dioxide dimethyl sulphoxide or dimethylformamide solution yields 9,10-di-hydrophenanthrene-9-carboxylic acid with conversions up to 55%.
This paper presents experimental results for the processing and mechanical properties of carbon fiber reinforced composites a newly developed amorphous, asymmetric, addition type polyimide (Triple-A PI). The imide oligomers were synthesized from reaction 2,3,3′,4′-biphenyltetracarboxylic dianhydride (a-BPDA), 4,4′-oxydiaminine (ODA), phenylethynyl phthalic anhydride (PEPA). Because amorphous structure, melting point melt viscosities polymer are relatively lower as compared with similar...

As part of our product development effort for PETI-330, an investigation to determine the effect a thermal cure cycle and postcure treatment on laminate properties was conducted. Laminates PETI-330/T650-35 carbon fabric (un-sized) were fabricated by resin transfer molding (RTM) using high temperature injector. The degassed at 525-550 °F (274-288 °C) subsequently injected into Invar tool cured 1 h 700 °F(371 °C). laminates characterized quality ultrasonic inspection acid digestion, dry glass...
Influence of isothermal dipping in hot distilled water for 200 ks on the mass gain carbon fiber reinforced polyimide (CFRP) was investigated. Dipping raised gain. Based kinetics equation, both reaction index (n) and kinetic constant (k) were obtained. Since n value is approximately 0.6 from 333 to 373 K, mode independent absorption temperature. results discussion, probably directional transport through fiber/polyimide cylindrical interface. On other hand, Arrhenius linear relationship...
