PRODUCTION DETAILS

Characteristics of steel structure:

1. High strength, used to build a structure with a large span and heavy load. Good plasticity, the structure will not suddenly break due to overload under normal conditions. Good toughness, suitable for working under dynamic load.

2. Easy to make and easy to connect. Easy installation and a short construction period

Features of aluminum alloy:

The aluminum alloy is made of pure aluminum added with some alloying elements, such as aluminum-manganese alloy, aluminum-copper alloy, aluminum-copper-magnesium hard aluminum alloy, aluminum-zinc-magnesium-copper superhard aluminum alloy. Aluminum alloy has better physical and mechanical properties than pure aluminum: easy processing, high durability, wide application range, good decorative effect, and rich color. Aluminum alloys are classified into rust-proof aluminum, hard aluminum, and super-hard aluminum. Each category has its own range of use and has its own code for users to choose. Its material properties are light, easy to process, and have a maximum force range, unlike carbon fiber in terms of strength. What does it mean? That is to say, carbon fiber has a strong ability to be applied in a certain fiber direction because of its fiber characteristics, but it is inferior in other directions. Several layers of carbon fiber may be used in the manufacture of a relatively large part, and the part will become layer by layer like shortbread when it exceeds the force. After the aluminum alloy has withstood a certain amount of force, it will slowly deform and damage.

Carbon fiber features:

Carbon fiber is a reinforcing material for advanced composite materials. It has a series of advantages such as lightweight, high strength, high modulus, chemical resistance, and small thermal expansion coefficient. It is summarized as follows:

1. The density of carbon fiber is the cubic meter, and the tensile strength of carbon fiber is above. Therefore, it has high specific strength and specific modulus, which is more than 7 times higher than the specific strength of most metals, and the specific modulus is more than 5 times that of the metal. Due to this advantage, the composite material can be widely used in aerospace, automobile industry, sports equipment and the like.

2. Good chemical resistance

As can be seen from the composition of carbon fiber, it is almost pure carbon, and carbon is one of the most stable elements. It is stable to acid, alkali and organic chemicals except for strong oxidizing acid.

1. Good wear resistance

When carbon fiber and metal are ground, they are rarely worn. Carbon fiber is used to replace the advanced friction material made of asbestos, which has been used as brake pad material for aircraft and automobiles.

2. Fatigue strength High carbon fiber structure is stable, the composite material produced, after stress experiments with millions of cycles of stress fatigue, its strength retention is still 60% and steel is 40%, aluminum mining is 30%, and glass just Only 20%-25%, so the safety factor of the design product, the carbon fiber composite is the lowest.
