Hybrid Laminate

Because of their high specific stiffness and strength, fiber reinforced plastics (FRP) are preferred lightweight materials. Recent developments show a growing industrial interest in the integration of thermoplastic FRP in complex structures for high volumes. However, there are still shortcomings for these materials concerning the insufficient energy absorption in case of failure and the limited opportunities available for the assembly with other components. Improvements in the crash performance can be achieved for instance with the selective reinforcement of the FRP structure with ductile metallic inserts. The present study shows the interlaminar shear strength and scanning electron microscope (SEM) samples of a novel load optimized hybrid composite consisting of a continuous fiber-reinforced thermoplastic matrix, in which a metal core is integrated.

Determining Factor

Studies and experimental data on the microstructure of the surface of samples of epoxy сarbon-fiber-reinforced plastics that have undergone long-term (up to 5 years) climatic aging in different climatic zones of Russia have been conducted: under conditions of the industrial zone of temperate climate (Moscow, MTsKI); temperate warm climate (Gelendzhik, GTsKI); a warm humid climate (Sochi, GNIP RAS). It is established that the determining factor for aging of carbon plastics is the duration of the complex effect of climatic factors: the longer the period of climatic aging, the more significant changes occur in the microstructure of the surface of the materials. The intensity of the aging process and the degree of microstructural changes in the surface of carbon plastics are affected by the features of the climatic zone. general regularities and features of the destruction of the surface of carbon plastics after a long-term exposure to climatic factors have been established on the basis of the analysis and systematization of the results of microstructural studies.
