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, perform better than any of its constituent parts. Also, in terms of design, with far fewer costs, a wider range of properties can be achieved.
Composites can be divided into three categories in a general classification:
1-polymer composite (PMC)
2-metal composite composites (MMC)
3-Ceramic Bed Composites (CMC)
The use of metal composite and ceramic substrate is most commonly used in automotive, framing and aerospace 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).
Alborz Petro Idea Toos, using the expertise of domestic experts and with the exclusive representation of PLT, in the field of composite materials (UV-Curing tape) and close scientific-experimental cooperation with that company, has been providing services in this field to the industries Country.
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.
