Aramid Fiber Kevlar Phone Case for 3D Printing Prototype & Mass Production

Product Description

Aramid fiber (KEVLAR) :
Aramid fiber is a special continuous fiber based on aramid that can absorb energy and has high toughness. When laid in Onyx or other composite matrix, the manufactured impact-resistant parts will hardly fail catastrophically (break). This fiber is particularly suitable for applications in harsh environments or under repeated loads.

KEVLAR: It is the brand name of an aramid fiber material product developed by DuPont in the United States. The original name of the material is "poly(p-phenylene terephthalamide)", and the repeating unit of the chemical formula is -[-CO-C6H4-CONH-C6H4-NH-]-. The amide group attached to the benzene ring is a para structure.

Mechanical Properties:
Strength: 3.6 GPa
Elongation modulus: 131 GPa
Elongation at break: 2.8%
Thermal properties:  Long-term use temperature: 180ºC
Axial thermal expansion coefficient: -2 × 10 ^ (-6) / K
Thermal conductivity: 0.048 W(m·K)


Kevlar Fiber Characteristics:

1. Permanent heat resistance and flame retardancy, the limiting oxygen index Loi is greater than 28. It can maintain stable performance in high temperature environment.

2. Permanent antistatic property.

3. Permanent acid, alkali and organic solvent resistance.

4. High strength, high wear resistance and high tear resistance. The strength is 5 times that of steel of the same quality, but the density is only one-fifth of that of steel. And it has good toughness, is easier to bend than other fibers, and can withstand greater impact and stretching without breaking easily. It is 8 times higher than ABS in impact strength, and 15-20% lighter than other reinforcing fibers, making it an ideal material for 3D printing.

5. No droplets are produced when encountering fire, and no toxic gases are produced. Kevlar can withstand high temperatures without melting, withstanding temperatures up to 400°F (204°C) continuously, making it suitable for fire-resistant clothing and environments.

6. Easy processing and molding: Kevlar material is easy to process and mold, and can meet the needs of various complex shapes and structures.

Applications:
1. Personal Protective Equipment (PPE)
   - Kevlar is widely used in making bulletproof vests, helmets, and gloves, providing critical protection for law enforcement and personnel.

2. Automotive and Aerospace Industries
   - Its lightweight and strong characteristics make Kevlar a popular choice for reinforcing vehicle parts, aircraft components, and even racing tires.

3. Construction
   - Kevlar is utilized in construction materials for reinforcing concrete, providing added strength and durability to structures.

4. Sports Equipment
   - Many sports goods, such as tennis rackets and bicycles, utilize Kevlar for enhanced performance and reduced weight.

5. Industrial Applications
   - Kevlar is used in industrial applications ranging from conveyor belts to ropes and cable reinforcements, benefitting from its strength and durability.
