“…As already mentioned, in addition to UV radiation, temperature is among the factors resulting in the destruction of polymer structure [20,21]. This has not escaped the attention of researchers seeking to determine the relationship arising between exposure to a change in conditioning temperature and progression in degradation [22][23][24][25][26]. Deter-mining the impact of conditioning of polymer composites on dynamic properties is important for analysing the properties of new materials, especially for specialised applications such as aerospace components [27].…”

The aim of this study is to determine the effect of environmental factors in the form of UV radiation and temperature on the amplitude-frequency behaviour of polymer composites (prepregs) based on a framework of thermosetting epoxy resin reinforced with high-strength R-glass fibres. Two series of composites with different fibre arrangements were prepared. The series had fibres arranged at angles of 30°, 45°, and 60°, at symmetric and asymmetric orientations in relation to the central layer. The composites were subjected to conditioning which simulated a six-month period of use in the spring and summer in the temperate warm transitional climate of Central and Eastern Europe. An UV QUV/SPRAY/RP accelerated aging chamber manufactured by Q-Lab Corporation was used for this purpose, and UV-A 340 lamps were used to simulate daylight. In addition, varying loads caused by sudden temperature changes were simulated using the Thermal Shock Chamber T/60/V2 Weisstechnik. Conditioned samples were tested using a TIRAvib 50101 electromagnetic exciter in combination with an LMS Scadias III controller and Test. Lab software. The results of the tests, in the form of amplitude-frequency diagrams in resonance regions, indicated that certain changes occurred as a result of the conditioning, which is a new development in the area of material tests. The results shed light on the effects of environmental conditions on the stiffness characteristics of composites, causing dynamic nonlinearities when operating at resonant frequencies.

“…The highest strain is obtained at a combination of 5 mm fiber length and a temperature of 25 ° C. This is because at low temperatures the bond between the matrix and the reinforcement becomes weak. The reason is the water vapor permeating the fibers damaging the fibers causing delamination [19], [20]. Strain increases due to the resistance response of the composite to the received tensile load so that the composite experiences stress and strain occurs as an effect of internal shifting at the atomic level on the particles that make up the composite, so that the composite experiences an increase in length or stretching.…”

Research on material engineering is widely developed in the precursors, composition of the material, and technique to create a composite. The layering and vacuum infusion resin are the developing technology to create the composites with the new characteristics and properties. This experiment is intended to find out the characteristics of layering carbon fiber reinforced by resin and is molded with vacuum infusion technique. The specimens of this experiment is layered-carbon fiber composites determined in three, four, five, six, and seven layers. The precursors of 220 and 240 carbon fibers are the main material of the composites. The tests conducted to the specimens are bending and tensile tests. The both tests are treated to reveal the mechanical properties of the composites. The least layers of 220 and 240 carbon fiber result the highest value of bending test, but the most number of carbon fiber layers show the opposite value. The results are reverse in the tensile test. The highest value of the tensile test is achieved by the most layers of carbon fiber, while the lowest value is in the least layers. This result is almost the same with the strain-stress, but overall the graphic is similarly increase to the most layers. Deduction achieved in this experiment is that the number of layers in the carbon fiber composites is significantly influencing the mechanical properties of the composite.

Composite truss core sandwich structures have the significant advantage in astronautic and aeronautic applications owing to their high specific stiffness and strength. In recent years, different composite sandwich panels have been designed, tested, and analyzed. The mechanical properties of composite materials may suffer when the material is exposed to high temperature, high humidity environments. Glass fiber reinforced plastics composite is extensively used as a structural material for pools, oil pipes and tanks because it has good corrosion resistance properties. In this work, the effect of temperature on PVC/PVC sandwich plates having 0.95 Wt.% glass fiber blended with different types of adhesives (epoxy, polyester, and polyvinyl chloride) is studied. Different temperatures (35 oC, 45 oC, 55 oC, 65 oC and 75 oC) as well as three times of exposure (2 hrs.,4 hrs. and 6 hrs.) is adopted. The mechanical properties such as tensile strength, ultimate strength, modulus of elasticity, energy to fracture, impact energy and adhesion shear at different temperatures are studied. The activation energy of PVC /PVC sandwich plates having glass fiber as reinforced material blended different adhesives was studied It has been found that the mechanical properties of PVC /PVC sandwich plates having 0.95 Wt.% glass fiber blended with different types of adhesives the mechanical properties are affected by temperature. In addition, it has been found that the activation energy of PVC /PVC sandwich plates having glass fiber as a reinforced material blended with polyvinyl acetate is the largest compared with epoxy and polyester.
