Abstract

The effect of various storage conditions on the properties of the carbon fiber prepreg VKU-74 based on a heat-resistant melt bismaleimide binder and equal-strength carbon fabric was studied. The assessment of the physical and mechanical characteristics of carbon fiber VKU-74 samples made from prepreg after storage under various conditions. Based on the results of the conducted research, the warranty period for storing prepreg in a room at a temperature of 20±5 °С, in a refrigerator at 0÷5 °С, and in a freezer at –18±5 °С has been established.

Keywords
