Composites: Composites can be considered as a physical mixture of two or more different materials which, according to certain criteria such as mechanical resistance or resistance to corrosive chemical agents, are better than any of their constituent parts. he does. Also, in terms of design, with far fewer costs, a broader range of properties can be achieved. The composites can be broken down into three subdivisions in the same division: 1. Composite with substrate Polymer Matrix Composite (PMC) 2 – Metal Matrix Composite Composites 3 – Ceramic Matrix Composite Composite Applications Metal and composite composite materials are used mainly in automotive and design industries. And the construction of frames and air-space industries.
Today, the most used composites are dedicated to polymer-based composites, which can be of high strength, impact resistance and high surface hardness, flexibility, excellent resistance to corrosive and chemical agents, lightness and manufacturing. Easy and fast to produce complex geometric shapes.
One of the most widely used applications (PMCs) is to reinforce metal or concrete structures against various loading and corrosivity and erosion factors, which in turn leads to the use of (PMCs) for reinforcing pipelines in cases such as corrosion Internal or external, change in line pressure or any changes in external loading on pipelines.
(PMCs) or polymer composite composites from a polymer such as vinyl ester or epoxy polyurethane, in the matrix phase (and using fibers such as glass fiber, carbon or Kevlar as a reinforcing phase).
It should be noted that the implementation methods and calculations are in accordance with the ASME PCC-2 and ISO / TS 24817 standards, and in particular cases, the Abaqus software is used.
