EFFECT OF ADDING NANO – POWDER ON COMPOSITE PIPES BEHAVIOR SUBJECTED TO MULTI STRESSES

الملخص

This paper presents numerical, analytical and experimental studies of composite system for the Nano composite pipe. Woven roving and roving (fiber glass and carbon) composite pipes with (2%) Carbon Nano powder /epoxy composite and (50%) volume fraction have been tested. The experimental work included manufacturing pipe specimens by two techniques; first was filament winding technique using roving materials and second was vacuum bag technique which used woven roving materials. Also filament device was designed and manufactured. Manufacturing of composite pipes has been done as a conventional pipe for inner diameter of (100mm) and wall thickness of (4mm). In numerical work: the ANSYS package version (11) with element shell (63) was applied to investigate the effect of internal pressure on composite pipes. Test rig was designed and perform to study the effects of internal pressure and bending load on composite pipes, as well as the tensile test was done for the specimens. In analytical solution expression was achieved to define the effects of combined stresses on composite pipes.
