| چکیده | ||
| در این تحقیق، تأثیر مقدار پرکننده و ماده جفت کننده MAPP بر ویژگی‌های فیزیکی و مکانیکی کامپوزیت پلی‌پروپیلن تقویت شده شده با آرد حاصل از ضایعات ناشی از هرس سالیانه برگ نخل خرما (رقم شاهانی) مورد مطالعه قرار گرفت. بدین منظور استفاده از سه سطح 30، 40 و 50 درصد آرد نخل خرما و دو سطح 4 و 6 درصد MAPP به عنوان عوامل متغییر در نظر گرفته شد. سپس خواص فیزیکی و مکانیکی نمونه‌های آزمونی شامل واکشیدگی ضخامت بعد از 2 و 24 ساعت غوطه وری در آب، مقاومت و مدول کششی، مقاومت و مدول خمشی و مقاومت به ضربه اندازه‌گیری شد. نتایج حاصل نشان داد که با افزایش آرد نخل خرما مقاومت خمشی، مقاومت کششی و مقاومت به ضربه کاهش و در مقابل واکشیدگی ضخامت، مدول خمشی، مدول کششی افزایش یافته‌اند. همچنین با بررسی اثر ماده جفت کننده مشخص گردید که با افزودن MAPP واکشیدگی ضخامت، مقاومت و مدول الاستیسیته کششی و خمشی کامپوزیت حاصل بهبود یافته است. این بدان معنی است که همراه با افزایش مصرف آرد نخل خرما، افزودن عامل جفت کننده منجر به بهبود کیفیت سطح مشترک شده و تغییرات قابل ملاحظه‌ای را خصوصا در پایداری ابعادی و مدول الاستیسیته حاصل کرده است. | ||

| چکیده [English] | ||
| In this research, the effect of the wood filler content and coupling agent (MAPP) on the physical and mechanical properties of Polypropylene reinforced with palm wood flour from the annual pruning of palm leaves (Shahani species) composite, were studied. For this purpose, the palm wood flour in three levels of 30%, 40%, 50% and two levels of Maleic anhydride grafted polypropylene 4% and 6% were used as variable factors. Then, the Physical and mechanical properties of samples, including thickness swelling after 2 and 24 hours of immersion in water, bending strength, bending modulus, tensile strength, tensile modulus and impact strength, were measured.The results showed that by increasing palm wood flour, the bending strength, tensile strength and impact strength were decreased but the thickness swelling, bending modulus, tensile modulus were increased. It was also found that by adding MAPP, thickness swelling, bending strength, bending modulus, tensile strength and tensile modulus were improved. The results revealed that at increased consumption of palm wood flour and adding coupling agent leads to improve quality of the interface and significant changes especially dimensional stability and MOE, are achieved. | ||
