KevlarŽ & Aramid - Ultra strong reinforcementAramid is a material formed by combining para-phenylenediamine and terephthaloyl chloride. This produces aromatic polyamide threads which are further refined to produce fibres. These fibres are woven into a very light, very strong cloth. When this cloth is combined with resin it produces a composite material which is 20 times stronger than steel with excellent torque and tensile strength, and excellent impact-resistant properties too.
Kevlar® is the well-known brand of aramid produced by the DuPont company, and is widely used in the aerospace and defence industries.
Key features of Aramid/Kevlar® include:
High Tensile Strength: Kevlar®/Aramid fibres are incredibly strong and have high tensile strength. Tensile strength refers to the ability of a material to withstand a pulling force without breaking.
Heat Resistance: Kevlar®/Aramid exhibits excellent heat resistance. It can withstand high temperatures without degrading, making it suitable for applications where exposure to heat is a concern.
Low Stretch: Kevlar®/ Aramid has a very low elongation to break, meaning it doesn't stretch much under load. More advantageous in applications where minimal stretching is crucial.
Lightweight: Despite its strength, Kevlar®/Aramid is a very lightweight fabric, which is beneficial in applications where weight is a critical factor.
Abrasion Resistance: Kevlar®/Aramid's resistance to abrasion makes it durable and long-lasting in applications where wear and tear are common such as skid pads on canoes.
Some of the many applications of Kevlar®/Aramid include:
Industrial Applications: Kevlar®/Aramid materials are used in various industrial and military applications, including the manufacturing of protective gear, such as body armor and helmets.
Aerospace: In the aerospace industry, Kevlar®/Aramid can be used in the construction of lightweight yet strong components for aircraft.
Composites: Kevlar®/Aramid cloth’s are often used to reinforce composite materials, such as in the construction of lightweight and high-strength structures.
Automotive/Leisure: Kevlar®/Aramid cloth and tape can be employed in the automotive and leisure industries for many applications.
It's important to note that the specific characteristics of Kevlar® tape can depend on varying factors such as different weave patterns, thicknesses, and any additional coatings or treatments applied during or after the manufacturing process.
