При изготовлении заготовок из полимерных композиционных материалов (ПКМ) для последующего автоклавного или другого вида формования применяют такие технологии, как автоматизированные выкладки волокон (Automated Fiber Placement — AFP) и лент (Automated Tape Laying — ATL). В процессе выкладки могут образовываться дефекты, частота возникновения которых зависит от сложности детали и технологических параметров (ширины выкладываемых лент, скорости выкладки и простоя, температуры выкладки, отклонения от расчетной траектории и др.). В работе представлен обзор основных дефектов, анализ причин их появления и влияния на физико-механические свойства композиционных материалов. Показано, что дефекты меняют толщину и снижают прочность ПКМ при растяжении и сжатии. Кроме того, неточность размещения волокон при использовании AFP-технологии негативно влияет на качество материалов. Приведенные результаты могут быть использованы при дальнейшем исследовании влияния дефектов на свойства ПКМ и причин, их вызывающих, а также при разработке перспективной универсальной вычислительной программы, с помощью которой можно сократить число соответствующих экспериментальных испытаний.

Technologies of automated laying out of fibers (Automated Fiber Placement — AFP) and tapes (Automated Tape Laying — ATL) are used in the manufacture of blanks from polymer composite materials (PCM) for subsequent autoclave or other type of molding. The frequency of defect formation upon laying depends on the complexity of the certain part and the technological parameters (the tape width, speed of laying and idle time, temperature, deviations from the calculated trajectory, etc.). We present a review of the main defects thus formed along with the analysis of the reasons for their appearance and their effect on the physical and mechanical properties of composite materials. It is shown that the defects change the thickness and reduce the strength of the PCM under tension and compression. Moreover, the inaccuracy of fiber placement when using the AFP technology has a negative effect on the quality of the materials. The results presented can be used in the further study of the effect of defects on the PCM properties and reasons for defect formation, as well as in developing promising universal computational program that can provide reduction of the number of corresponding experimental tests.
