Effect of Nature Materials Powders on Mechanical and Physical Properties of Glass Fiber / Epoxy Composite

Abstract

In the present study composites were prepared by Hand lay-up molding. The composites constituents were epoxy resin as the matrix, 6% volume fractions of Glass Fibers (G.F) as reinforcement and 3%, 6% of nature material (Rice Husk Ash, Carrot Powder, and Sawdust) as filler. Density, water absorption, hardness test, flexural strength, shear stress measurements and tests were conducted to reveal their values for each type of composite. True density results had shown an incremental increase with volume fraction increasing and water absorption, hardness, flexural strength and shear stress results had shown an incremental increase with volume fraction increasing with smaller particle size. ‫ﻣﺴﺎﺣﯿﻖ‬ ‫ﺗﺄﺛﯿﺮ‬ ‫طﺒﯿﻌﯿ‬ ‫ﻣﻮاد‬ ‫اﺳﺎﺳﮭﺎ‬ ‫ﺔ‬ ‫ﻋﻠﻰ‬ ‫اﻟﺨﻮاص‬ ‫و‬ ‫ﻣﯿﻜﺎﻧﯿﻜﯿﺔ‬ ‫ﻣﻦ‬ ‫ﻣﺮﻛﺒﺔ‬ ‫ﻟﻤﻮاد‬ ‫ﻓﯿﺰﯾﺎوﯾﺔ‬ ‫زﺟﺎج‬ ‫واﻟﯿﺎف‬ ‫اﯾﺒﻮﻛﺴﻲ‬ ‫اﻟﺨﻼﺻﺔ‬ ‫اﻟﯿﺪوﯾﺔ‬ ‫اﻟﻘﻮﻟﺒﺔ‬ ‫طﺮﯾﻘﺔ‬ ‫ﺑﻮاﺳﻄﺔ‬ ‫ﻣﺘﺮاﻛﺒﮫ‬ ‫ﻣﻮاد‬ ‫ﺗﺤﻀﯿﺮ‬ ‫اﻟﺒﺤﺚ‬ ‫ھﺬا‬ ‫ﻓﻲ‬ ‫ﺗﻢ‬. ‫راﺗﻨﺞ‬ ‫ﻣﻦ‬ ‫ﻣﻜﻮﻧﺔ‬ ‫اﻟﻤﺘﺮاﻛﺒﺔ‬ ‫اﻟﻤﻮاد‬ ‫ﺣﺠﻤﻲ‬ ‫ﺑﻜﺴﺮ‬ ‫اﻟﺰﺟﺎج‬ ‫وﺑﺄﻟﯿﺎف‬ ‫اﺳﺎس‬ ‫ﻛﻤﺎده‬ ‫اﻻﯾﺒﻮﻛﺴﻲ‬ 6% ‫وﻛﺬﻟﻚ‬ 3% ‫و‬ 6 % ‫اﻟﻄﺒﯿﻌﯿﺔ‬ ‫اﻟﻤﻮاد‬ ‫ﻣﻦ‬ ‫ﻛﺤﺸﻮة‬) ‫رﻣﺎد‬ ‫اﻻرز‬ ‫ﻗﺸﻮر‬ , ‫اﻟﺠﺰر‬ ‫ﻣﺴﺤﻮق‬ , ‫ﺟﺎوي‬ ‫ﺧﺸﺐ‬ ‫ﺑﻮدرة‬ (. ‫واﻣﺘﺼﺎﺻ‬ ‫اﻟﻜﺜﺎﻓﺔ‬ ‫وﻓﺤﻮﺻﺎت‬ ‫ﻗﯿﺎﺳﺎت‬ ‫اﺟﺮاء‬ ‫ﺗﻢ‬ ‫ﯿ‬ ‫اﻟﻤﺎء‬ ‫ﺔ‬ ‫اﻟﺼﻼدة‬ ‫وﻓﺤﺺ‬ , ‫اﻻﻧﺤﻨﺎء‬ ‫ﻣﻘﺎوﻣﺔ‬ , ‫اﻟﻤﺘﺮاﻛﺒﺔ‬ ‫اﻟﻤﻮاد‬ ‫ﻣﻦ‬ ‫ﻧﻮع‬ ‫ﻟﻜﻞ‬ ‫ﻗﯿﻤﮭﺎ‬ ‫ﻋﻦ‬ ‫ﻟﻠﻜﺸﻒ‬ ‫اﻟﻘﺺ‬ ‫اﺟﮭﺎد‬. ‫اﺟﺮاء‬ ‫ﻋﻨﺪ‬ ‫اﻟﻜﺜ‬ ‫اﺧﺘﺒﺎرات‬ ‫ﺎﻓﺔ‬ ‫اﻟﺠﺤﻤﻲ‬ ‫اﻟﻜﺴﺮ‬ ‫زﯾﺎدة‬ ‫ﻣﻊ‬ ‫ﺗﺰداد‬ ‫اﻟﻜﺜﺎﻓﺔ‬ ‫ﺑﺎن‬ ‫اظﮭﺮت‬ ‫اﻟﻨﺘﺎﺋﺞ‬ ‫ﻓﺎن‬ ‫اﻟﻤﺎء‬ ‫اﻣﺘﺼﺎﺻﯿﺔ‬ ‫ﺑﺎن‬ ‫اظﮭﺮت‬ ‫واﻟﻨﺘﺎﺋﺞ‬ ‫و‬ ‫اﻟﺼﻼدة‬ ‫ﺣﺒﯿﺒﻲ‬ ‫ﺣﺠﻢ‬ ‫اﺻﻐﺮ‬ ‫ﻣﻊ‬ ‫و‬ ‫اﻟﺠﺤﻤﻲ‬ ‫اﻟﻜﺴﺮ‬ ‫زﯾﺎد‬ ‫ﻣﻊ‬ ‫ﯾﺰداد‬ ‫ﻗﺺ‬ ‫اﺟﮭﺎد‬ ‫واﻗﺼﻰ‬ ‫اﻻﻧﺤﻨﺎء‬ ‫وﻣﻘﺎوﻣﺔ‬ .
