Investigation of Tensile and Impact of Composite Materials Reinforced with Natural Materials

Abstract

This work focuses on studying the effect of Data Seeds (DS) and Olive Seeds (OS) particles on tensile and impact properties of epoxy resin. Olive and dates seeds powder were added to epoxy matrix at weight fraction (0, 8, 13, &18 wt %) with grain size (300, 450 & 600µm). The composite specimens were prepared by Hand-Lay-up technique and cut according to standard test. It's found the higher value of modulus of elasticity and tensile strength happened at (=18 wt %) and grain size (300µm) for specimens reinforced with olive seeds powder, but obtained the lower percentage of elongation at break, impact strength and fracture toughness at this value. Also the mathematical model results show that the weight fraction of powder have higher effect than grain size on properties. ‫والصدمة‬ ‫الشد‬ ‫عن‬ ‫التقصي‬ ‫طبيعية‬ ‫بمواد‬ ‫المقواة‬ ‫المتراكبة‬ ‫للمواد‬ ‫الخالصة‬ ‫يتركز‬ ‫تأثير‬ ‫دراسة‬ ‫على‬ ‫العمل‬ ‫ھذا‬ ‫مسحوق‬ ‫خواص‬ ‫على‬ ‫والتمر‬ ‫الزيتون‬ ‫نوى‬ ‫الشد‬ ‫والصدمة‬ ‫لمادة‬ .‫االيبوكسي‬ ‫من‬ ‫كل‬ ‫أضافة‬ ‫تم‬ ‫مسحوق‬ ‫االيبوكسي‬ ‫االساس‬ ‫مادة‬ ‫الى‬ ‫والتمر‬ ‫الزيتون‬ ‫نوى‬ ‫بال‬ ‫كسور‬ ‫التالية‬ ‫الوزنية‬) 0, 8, 13 &18 wt% ‫حبيبي‬ ‫حجم‬ ‫مع‬ (300, 450 & 650µm) ‫الخلط‬ ‫بطريقة‬ ‫المتراكبة‬ ‫العينات‬ ‫حضرت‬ .(‫ت‬ ‫اجراء‬ ‫تم‬ ‫ثم‬ ‫اليدوي‬ ‫لمعامل‬ ‫قيم‬ ‫اعلى‬ ‫بإن‬ ‫النتائج‬ ‫بينت‬ .‫فحص‬ ‫لكل‬ ‫القياسية‬ ‫المواصفة‬ ‫حسب‬ ‫للعينات‬ ‫قطيع‬ ,‫المرونة‬ ‫و‬ ‫عند‬ ‫حدثت‬ ‫شد‬ ‫اجھاد‬ ‫وزني‬ ‫كسر‬ (=18 wt%) ‫حبيبي‬ ‫وحجم‬ (300µm) ‫ب‬ ‫التقوية‬ ‫عند‬ ‫مسحوق‬ ‫نوى‬ ‫قيمة‬ ‫أقل‬ ‫لكن‬ ‫الزيتون‬ ‫لأل‬ ‫ستطالة‬ ‫ال‬ ‫ومقاومة‬ ‫نسبية‬ ‫ال‬ ‫ومتانة‬ ‫صدمة‬ ‫ال‬ .‫النسبة‬ ‫ھذه‬ ‫عند‬ ‫حدثت‬ ‫كسر‬ ‫ك‬ ‫ذلك‬ ‫بينت‬ ‫نتائج‬ ‫الموديل‬ ‫ال‬ ‫ا‬ ‫بإن‬ ‫رياضي‬ ‫لكسرالوزني‬ .‫الخواص‬ ‫على‬ ‫الحبيبي‬ ‫الحجم‬ ‫من‬ ‫أكثر‬ ‫تأثير‬ ‫ذو‬ ‫كانت‬ ‫التقوية‬ ‫لمادة‬ INTRODUCTION composite material is a macroscopic combination of two or more distinct materials, having a recognizable interface between them. Composites are used not only for their structural properties, but also for electrical, thermal,
