چکیده

توسعه صنعت هوافضا مستلزم تلاش دائم برای طراحی و ساخت سازه‌های سبک‌تر و کارآمدتر است. سازه‌های کامپوزیتی شبکه‌ای، کاربرد نوین و فناورانه از کامپوزیت‌ها برای کاهش وزن سازه‌های هوافضایی است. استفاده از روش‌های کارآمد و پیشرفته مانند بافت دورانی در ساخت سازه‌های استوانه‌ای کامپوزیتی شبکه‌ای مورد نیاز است. در این مقاله یک سازه استوانه‌ای شبکه‌ای کامپوزیتی تقویت شده با الیاف کربن بافته شده با کاربرد هوافضایی مورد مطالعه قرار گرفته‌ است. یک روش برای تعیین پارامترهای ساختاری پیش‌سازه، یک فرآیند جدید برای تولید سازه شبکه‌ای و همچنین یک روش برای تعیین پارامترهای تکنولوژیکی دستگاه بافت دورانی به منظور تولید پیش‌سازه توسعه داده شده‌ است. یک سازه نمونه ساخته‌ شده و مورد آزمایش قرار گرفته ‌است. مطالعات نرم افزاری و تجربی نمونه‌های سازه شبکه‌ای به منظور صحت سنجی روش‌های تعیین پارامترهای مکانیکی، سازه‌ای و تکنولوژیکی انجام شده است.

چکیده [English]

Development in the aerospace industry is linked to the continuous pursuit of lightweight designs. Open-architecture composite structures are a new and novel use of composites for minimal-weight component design. It is reasonable to use efficient and advanced techniques such as radial braiding in the manufacturing of composite lattice tubular structures. In this article, an aerospace composite lattice tubular structure with a braided reinforcement system is studied. A method is developed to determine the parameters of the preform reinforcement. A new process has been created for the manufacture of lattice structures with a braided reinforcement system. A methodology has been developed for determining the technological parameters of radial braiding. A sample structure is manufactured and tested. Experimental studies of lattice structure samples were carried out in order to verify the methods for determining mechanical, structural, and technological parameters.
