ملخص المقالة :
مواد مرکب بسیار پرشده از دو جزء ماتریس پلیمری و پرکننده‌های مختلف با کسر وزنی بیشتر از %30 تشکیل شده است و کاربرد فراوانی در سامانه های دفاعی و موتورهای هوا فضایی دارند. هریک از پودرهای فلزی باتوجه به خواص، نوع دانه‌بندی، نوع اندازه ذرات، مورفولوژی می‌توانند بر رفتار جریان ماده مرکب بسیار پرشده تاثیرگذار باشند. بررسی سه نوع پودر فلزی، آلومینیوم، منیزیم و بور که بیشترین کاربرد را در ماده مرکب بسیار پرشده دارند، در این مطالعه انجام شده است. نتایج حاصل از بررسی رفتار جریان نشان داد که با افزایش اندازه ذرات جامد، محتوای پودرهای فلزی و هم چنین عامل شبکه کننده، گرانروی و تنش تسلیم دوغاب مواد مرکب افزایش می یابد و موجب می شود که خواص جریان یافتن دوغاب بدتر گردد و عمرکاربری آن کوتاه¬تر شود. افزایش گرانروی به علت ذرات جامد ریزتر و افزایش وزن مولکولی و تشکیل اتصالات عرضی در ساختار پیش‌پلیمر می‌باشد. گرانروی دوغاب مواد مرکب با افزایش سرعت برشی کاهش می یابد و رفتارغیرنیوتنی شبه پلاستیک را از خود نشان می¬دهد و مقدار آن به سرعت و زمان نیروی برشی اعمال‌شده بستگی دارد. ترکیب پودر فلزی بور با پودر منیزیم و یا آلومینیوم می¬تواند تا حد زیادی رفتار جریان ماده مرکب بسیار پر شده را بهبود بخشد.
