Enhance and Characterize the Mechanical Properties of PVC In Terms of Creep and Fatigue by Conducting Dry and Wet Carbon Fibers

Abstract

This research is aiming to enhance an characterize the mechanical properties of PVC by conducting two kinds of mechanical tests.  creep and fatigue are considered to implemented to investigate the resistance on dry and wet carbon fibers. Sheets of  PVC have been employed to perform the test .furthermore,  dry and wet carbon fibers  are also used to formulated with the PVC sheets  and resin agglutinant (80EF) is used as a matrix. A number  (2,4,6,8,10) layers of wet and dry carbon fiber mat have been placed  between two outer sheets of PVC and using agglutinant  type(EF 80) to bind the layers.  A load (20 kgf) for (24hours) has been used in order  to complete solidification process of agglutinant . later, electric saw  has been used to cut samples by using  standard specimen for the creep and fatigue test. To perform testing process, the device (UK Norwood)  with digital reading unit type (SONY 1,1) was used to measure durability of samples to creep  and device of fatigue . After the comparison between (creep and fatigue) for samples with polymer basis of PVC and reinforcement by wet and dry carbon fibers ,it has been found that composite material   reinforced with dry fibers are the lighter and best in terms of properties of creep and fatigue since the number of  fatigue courses reinforced with dry fibers have increased about (500000-1250000) courses compared to its equivalents for reinforced  sample with wet fibers .As that resistance of reinforced sample with wet fibers for creep was the best.
