Aromatic polyamide fibers, also known as aramid fibers, are heat-resistant and high-strength synthetic fibers. Alfa Chemistry offers a range of aromatic polyamide fiber products as your high-performance fiber solutions.
Aramid fibers have the following unique characteristics, which are due to their rigid polymer molecular structure with strong crystal orientation and tight interactions between polymer chains due to hydrogen bonding.
Materials | Strength to weight (KN.m/kg) | Ultimate Strength (MPa) | Density (g/cm3) |
---|---|---|---|
Aramid fiber | 2514 | 2757 | 1.44 |
Carbon Fiber | 2457 | 4137 | 1.75 |
E Glass Fiber | 1307 | 3450 | 2.57 |
S Glass Fiber | 1906 | 4710 | 2.47 |
Nylon | 69 | 75 | 1.15 |
Aramid fiber has excellent comprehensive properties and is widely used in the reinforcement of composite materials. Aramid fiber composites have the advantages of high impact and crack resistance, low density/low weight, abrasion resistance, and low dielectric constant of about 3.85 (10 GHz). For example, the impact resistance of aramid fiber composites can reach 5 times that of carbon fiber composites, and aramid fiber composites are about 20% lighter than carbon fiber composites.
