Abstract
Aramid fibers are synthetic aromatic polyamide fibers that are currently used in demanding composite applications, such as tires, hoses, bulletproof vests and helmets. They are manufactured by solution spinning from sulphuric acid solution. Due to the manufacturing method and the chemical nature of aramid, the fiber surface is very smooth and inert, which affects the adhesion properties of the fibers negatively. Several surface treatment methods are used to increase the adhesion between the fibers and matrix materials in composite products. Some of these methods have major drawbacks, creating pressure to develop new surface treatment methods for the industry. In this article a surface treatment method that uses microwave irradiation combined with reactive chemicals is used to increase the adhesion between the aramid fibers and a rubber matrix. The method increased the adhesion by a factor of~ 3.5 when …
