Thermal expanding is the important property that defines the stress–strain condition of GRP structures exploited under heating and having limited thermal resistance. So, the GRPs’ thermal expanding prediction is the actual requirement of such structures design. The experimental accurate dilatometric study resulted in the non-linearity of thermosetting polymers and plastics thermal expanding under heating. The polymers and plastics thermal expanding coefficient (CTE) is non-linearly increasing under heating before glassing temperature (Tg). Using the previous polymers and GRPs modelling experience and experimental dilatometric results, the non-linear adequate prediction models of their CTE were proposed and proved. The new compensative wave model of polymers’ CTE and multi-layer model of GRPs’ CTE were proposed and successfully tested. A prediction of the temperature dependences of the thermal expansion coefficients of various thermoset polymer binders and data on the reinforcement structure was performed based on the experimentally obtained temperature dependences of the CTEs of GRPs. The prediction was performed using the finite-element homogenization method in the Material Designer module of the academic version of the Ansys package. A satisfactory concurrence of the numerical results of the prognosis and the experiment for all considered cases is observed in the temperature range from 50 to 100 °C, after glass transition temperature best coincidence of numerical values of CTE is obtained for glass-reinforced plastics on epoxy resin, which were not subjected to thermal aging.

Many alloys and aluminum composites have been produced in recent years for improved material performance. Al 6061 is now an aluminum alloy with a wide range of uses owing to its excellent microstructure. For the manufacture of aluminum matrix composites (AMC), it is a wise option for the matrix. The in-situ process produces Al 6061 aluminum alloy matrix composites, according to this research. It investigates the mechanical properties of Al 6061 composites, modern in-situ fabrication, processing conditions, and multiple reinforcements employed. Numerous researches have shown that the latest in-situ process is commonly used and ideal for designing Al-6061 Alloy composites reinforcing TiC, TiB2, Al2O3, SiC, and other inorganic, biological elements, hybrid, and nanomaterials. A variety of researchers indicated that higher reinforcement material increased the composites' mechanical and tribological properties. Moreover, hybrid composites outperformed single-reinforcement composites in terms of material properties. Industrial and agricultural residues are also recorded to be used in hybrid composites. Scientific investigations should concentrate on in-situ processing and material characterization of Al 6061 nanocomposites, which have a lot of promise as exotic technologies.
