Preparation of CF/Ceramic Composite Using 2.5-dimensionally (Quintuple) Wove CF Cloth

buckling of viscoelastic composite plates using the finite strip method

در سال های اخیر، تقاضای استفاده از تئوری خطی ویسکوالاستیسیته بیشتر شده است. با افزایش استفاده از کامپوزیت های پیشرفته در صنایع هوایی و همچنین استفاده روزافزون از مواد پلیمری، اهمیت روش های دقیق طراحی و تحلیل چنین ساختارهایی بیشتر شده است. این مواد جدید از خودشان رفتارهای مکانیکی ارائه می دهند که با تئوری های الاستیسیته و ویسکوزیته، نمی توان آن ها را توصیف کرد. این مواد، خواص ویسکوالاستیک دارند....

Preparation of new composite membranes for water desalination using electrodialysis

The use of polyethersulfone (PES), an excellent but highly hydrophobic thermoplastic, as a matrix material for ionexchange membranes was investigated. To make PES ion-exchangeable, sulfonate groups were introduced to the polymer chains by sulfonation reaction with chlorosulfonic acid. The degree of sulfonation of sPES was estimated to be 21%. Preliminary experiments investigated the effect of p...

Preparation and assessment of Dimensionally Stable Anodes (DSAs) Summary: Dimensionally Stable Anodes are used in non-ferrous extractive electrometallurgy

1. Preparation and assessment of Dimensionally Stable Anodes (DSAs) Summary: Dimensionally Stable Anodes are used in non-ferrous extractive electrometallurgy (copper, zinc...) and in water electrolysis for the oxygen evolution. They substitute in electrometallurgy lead alloys electrodes subject in normal industrial operating conditions to creep. The objective of this work is to continue what wa...

Mixed-mode I/II Interlaminar Fracture of CF/PEI Composite Material

Failures in composite materials occur mainly due to interlaminar fracture, also called delamination, between laminates. This indicates that characterizing interlaminar fracture toughness is the most effective factor in the fracture of composite materials. This study reports investigation on mixed-mode interlaminar fracture behaviour in woven carbon fibre/polyetherimide (CF/PEI) thermoplastic co...
