“…When these items reach the end of their useful service life, they must be disposed of or demolished. [19]. The reclamation and recycling of discarded rubber have significant consequences for environmental preservation, energy conservation, re-use with or in place of virgin rubber, cost savings, and a change in the processing behavior of rubber compounds.…”

In this article, waste fibres from the recycling tire process with a different percentage of addition (0, 2.5, 5, 7.5, 10, 12.5) were mixed to increase their tensile strength, tear resistance, and bending resistance with natural rubber NR. The effect of short fiber on composite mechanical properties was investigated. Despite substantial research on the mechanical characteristics of rubber products reinforced with fiber waste, the experimental work focused on identifying precursory physical mechanisms that are responsible for fracture behavior during tests and structural monitoring. The findings reveal that milling and vulcanization conditions have a significant role in enhancing mechanical characteristics. The waste fibres and natural rubber provide strong interfacial adhesion during two rolls of milling and vulcanization at 140°C. Waste fiber may boost the tensile strength of a composite material by up to 7.5% of waste fiber, with a slight decrease at 10% and 12.5%. The flexing test findings showed that adding fiber to the recipe improved it by up to 7.5% before gradually degrading, and it is obvious that the recipes' tear resistance improves in comparison to the basic recipe. The discoveries have the potential to increase the tensile strength, tear resistance, and flexing resistance of industrially manufactured rubber conveyor belts, which are important physical properties in engineering applications.

“…Writing a FEM code in MATLAB and computing the failure load for each lamina in composite laminate using a number of different of failure criteria, including the maximum strain and stress failure criterion and the Tsai-Hill, Tsai-Wu, and Hoffman failure theories [12,13]. Other studies discussed the effect of some additives on the mechanical behaviour of some types of polymers such as synthetic and natural rubber [14][15][16]. The strength of fiber-reinforced composite laminates that have been subjected to three different forms of loading: shear load, compression load, tension load.…”

During this work, the roof of the car was used as an engineering application to study and monitor the occurrence of failures under the influence of various loads. The shells are made of multilayer composite materials using epoxy resin reinforced with carbon fiber and aluminium oxide granules as reinforcing materials to increase the impact resistance that vehicles may be exposed to while driving, in addition to other loads and conditions such as vibration and constant exposure to moisture and sunlight. The simulation program was used the finite elements method through software Abaqus program in addition to the program MATLAB v.2020a to process the data obtained from the method that used in this study. The results showed that the specified failure criteria work well for predicting the overall structural response such as strain, stress, maximum force and displacement. The losses of energy of impact collision increase as an increase in impact velocity. The dissipation of energy which depend on the stress and strain distribution during elastic deformations. The effect of thickness of the lamina plays an important role in health monitoring the structure.
