Determination of Some Mechanical Properties of Unsaturated Polyester Reinforced with Glass Fiber and Plam Fiber

Abstract

In this work a composite materials is prepared containing matrix of polymer (unsaturated polyester) reinforced with different reinforcing materials (glass fiber + plate fiber) in different values of volume fraction %. All samples for to mechanical tests were prepared by hand layup process. The mechanical tests can be classified into: bending, tensile strength, tensile strength at break, elongation at break and hardness. The study of mechanical test shows that the mechanical properties increase with the increase in volume fraction. Keywords: unsaturated polyester, glass fiber, palm fiber, polyester mechanical properties ‫ﺑﺎﻟﯿﺎف‬ ‫اﻟﻤﺪﻋﻢ‬ ‫ﻣﺸﺒﻊ‬ ‫اﻟﻐﯿﺮ‬ ‫اﺳﺘﺮ‬ ‫ﻟﻠﺒﻮﻟﻲ‬ ‫اﻟﻤﯿﻜﺎﻧﯿﻜﯿﺔ‬ ‫اﻟﺨﺼﺎﺋﺺ‬ ‫دراﺳﺔ‬ ‫اﻟﺰﺟﺎج‬ ‫واﻟﯿﺎف‬ ‫اﻟﻨﺨﯿﻞ‬ ‫اﻟﺨﻼﺻـــــــﺔ‬ ‫ﺗﻢ‬ ‫اﻟﺤﺎﻟﻲ‬ ‫اﻟﺒﺤﺚ‬ ‫ﻓﻲ‬ ‫ﺟﺪﯾﺪة‬ ‫ﻣﺮﻛﺒﺔ‬ ‫ﻣﻮاد‬ ‫ﺗﺤﻀﯿﺮ‬ ‫ﻦ‬ ‫ﻣ‬ ‫ﻮن‬ ‫ﯾﺘﻜ‬ ، ‫ﻮﻟﯿﻤﺮي‬ ‫ﺑ‬ ‫ﻮط‬ ‫ﻣﺨﻠ‬ ‫ﻦ‬ ‫ﻋ‬ ‫ﺎرة‬ ‫ﻋﺒ‬ ‫ﻲ‬ ‫ھ‬ ‫اﻟﺘﻲ‬ ‫ﻮﻟﻲ‬ ‫ﺑ‬ ‫ﻣﺰج‬ ‫ﺒﻊ‬ ‫ﻣﺸ‬ ‫ﺮ‬ ‫ﻏﯿ‬ ‫ﺘﺮ‬ ‫اﺳ‬ ‫ﺎﻓﺔ‬ ‫اﺿ‬ ‫ﻊ‬ ‫ﻣ‬ ‫ﺐ‬ ‫ﻧﺴ‬ ‫ﮫ‬ ‫ﺣﺠﻤﯿ‬ ‫ﺔ‬ ‫ﻣﺨﺘﻠﻔ‬ ‫ﻦ‬ ‫ﻣ‬ ‫واﻟﯿ‬ ‫ﻞ‬ ‫اﻟﻨﺨﯿ‬ ‫ﺎف‬ ‫اﻟﯿ‬ ‫ﻰ‬ ‫ﻋﻠ‬ ‫ﺎج‬ ‫اﻟﺰﺟ‬ ‫ﺎف‬ ‫اﻟﺘﻮاﻟﻲ‬. ‫اﻟﻤﯿﻜﺎﻧﯿﻜﯿﺔ‬ ‫اﻻﺧﺘﺒﺎرات‬ ‫ﻓﻲ‬ ‫اﻟﻤﺴﺘﺨﺪﻣﺔ‬ ‫اﻟﻌﯿﻨﺎت‬ ‫ﺗﺤﻀﯿﺮ‬ ‫ﻓﻲ‬ ‫اﻟﯿﺪوﯾﺔ‬ ‫اﻟﻘﻮﻟﺒﺔ‬ ‫ﻃﺮﯾﻘﺔ‬ ‫اﺳﺘﺨﺪام‬ ‫ﺗﻢ‬. ‫ﺎء‬ ‫اﻻﻧﺤﻨ‬ ‫ﺎرات‬ ‫اﻻﺧﺘﺒ‬ ‫ﻤﻨﺖ‬ ‫ﺗﻀ‬ ‫ﻲ‬ ‫واﻟﺘ‬ ‫ﺔ‬ ‫اﻟﻤﯿﻜﺎﻧﯿﻜﯿ‬ ‫ﺎرات‬ ‫اﻻﺧﺘﺒ‬ , ‫ﺪ‬ ‫اﻟﺸ‬ ‫ﮫ‬ ‫ﻣﻘﺎوﻣ‬ , ‫ﻼدة‬ ‫اﻟﺼ‬ , ‫ﺎﺋﺞ‬ ‫ﻧﺘ‬ ‫ﺖ‬ ‫وﻛﺎﻧ‬ ‫اﻟﻤﯿﻜﺎﻧﯿﻜﯿﺔ‬ ‫اﻻﺧﺘﺒﺎرات‬ ‫ا‬ ‫اﻟﺤﺠﻤﯿﮫ‬ ‫اﻟﻨﺴﺐ‬ ‫ﺑﺰﯾﺎدة‬ ‫ﺗﺰداد‬ ‫اﻟﻨﺨﯿﻞ‬ ‫واﻟﯿﺎف‬ ‫ازﺟﺎج‬ ‫اﻟﯿﺎف‬ ‫ﻣﻦ‬ ‫ﻟﻤﻀﺎﻓﮫ‬ .
