Abstract

The article is devoted to the study of the effect of the storage time of lined and uncured polymer composite material made of carbon fiber based on a bundle filler, unidirectional carbon fabric and equal-strength carbon fabric before autoclave forming on the occurrence of the warping process of flat monolithic elements. It was found that prolonged (more than five days) storage of the prepreg after laying out before molding negatively affects the warping of the panel. The development of technological recommendations in accordance with the results obtained will ensure a reduction in the share of defective finished products.
