Mechanical analysis of fiber-reinforced plastics using an elastoplastic-damage constitutive equation considering asymmetric material behavior

Der globale Bedarf an faserverstärkten Kunststoffen (CFK) wächst aufgrund seiner herausragenden Eigenschaften gegenüber konventionellen Leichtbauwerkstoffen in der Automobil- sowie Luft- und Raumfahrtbranche stetig an. Für deren Endbearbeitung kommen überwiegend Fräsprozesse zum Einsatz, welche Verschnitt in Form von Faserbündeln im Mikrobereich erzeugen. Ein vielversprechender Ansatz die Ressourceneffizienz zu erhöhen, ist der Einsatz der Fräspartikel als Füllmaterial in Thermoplasten.   Due to the outstanding material properties of fiber reinforced plastics towards conventional lightweight materials, its global demand in the automotive and the aeronautical sector is growing steadily. For the machining of final contours, milling processes are mainly utilized, which create chips in form of fiber bundles in the micro range. A promising approach to increase the resource efficiency is the use of the milling particles as filler material in thermoplastic materials.

Materials Used

Glass fiber reinforced plastics (GFRP) is an immensely versatile material which combines lightweight with inherent strength. For the properties of sustainability, energy efficiency and reduction of CO2 of GFRP, they can be used in green building as a kind of the energy-efficient and environment-friendly material instead of the conventional materials. Based on the less elastic modulus and lower wave-transparent properties of glass fiber reinforced plastics for unsaturated polyester resin (UPR-FRP), a new kind of glass fiber reinforced plastics based modified unsaturated polyester (MUPR-FRP) was put forward. This paper presents material behavior and technical process of the new MUPR-FRP. For the modified property, the MUPR-FRP members may have the well superiority compare with the steel and the concrete materials used in strengthening engineering and special loading resistance.

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.
