The recovery and reuse of glass fibres from manufacturing waste and end-of-life composites in an environmentally-friendly, cost-effective manner is one of the most important challenges facing the thermosetting polymer composites industry. A number of processes for recycling fibres from such materials are available or under development. However, nearly all options deliver recycled glass fibres t...

Carbon fibre reinforced polymers (CFRP) were introduced to the aerospace, automobile and civil engineering industries for their high strength and low weight. A key feature of CFRP is the polymer sizing - a coating applied to the surface of the carbon fibres to assist handling, improve the interfacial adhesion between fibre and polymer matrix and allow this matrix to wet-out the carbon fibres. I...

A novel and facile approach to prepare hybrid nanoparticle embedded polymer nanofibers using pressurised gyration is presented. Silver nanoparticles and nylon polymer were used in this work. The polymer solution's physical properties, rotating speed and the working pressure had a significant influence on the fibre diameter and the morphology. Fibres in the range of 60-500nm were spun using 10wt...

یک سری از مواد رنگزای مونو آزو اسیدی بر پایه نفتالیمید با بکاربردن 4-آمینو –n- متیل بوتیل -8,1- نفتالیمید بعنوان جز دی آزوته شونده و شفرز اسید h-اسید و j- اسید اجزا جفت شوند سنتز شدند. مشتقات مختلف 4-آمینو نفتالیمید به وسیله فرایندهای استاندارد از آسنفتین بعنوان ماده شروع کننده تهیه شدند. ابتدا آسفتین تحت واکنش نیترودار کردن قرار گرفت و 5-نیترواسسنفتین بدست آمد. این ماده اکسید شد تا 4-نیترو -1,...

Nanocarbon-based conducting fibres have been produced using solution- or dry-spinning techniques. Highly conductive polymer-composite fibres containing large amounts of conducting nanomaterials have not been produced without dispersants, however, because of the severe aggregation of conducting materials in high-concentration colloidal solutions. Here we show that highly conductive (electrical c...
