Aramid/Kevlar fibers can be used as reinforcement alone, but also combined with other fibers. This way the properties of the composing fibers are enhanced by synergy. Synergy is the interaction of multiple elements in a system to produce an effect different from or greater than the sum of their individual effects [definition from wikipedia]. In other words, when two or more fibers are combined, the resulting material has a tendency to keep the «good» properties and drop the «bad» ones. For this reason, hybrid fabrics woven in many styles are usually a favorite choice of many composites manufacturers and are used extensively. Aramid fibers can be woven to hybrid fabrics with:

Carbon fiber
 Examples
  - In plain weave (CK170P)

  - In twill weave (CK210T2)

Fiberglass
 Examples
  - In plain weave (KG251P)

  - In twill weave (KG250T2)

  - In multi-axials (KG376X)

Vectran fiber (V200T2)

Polyester-Diolen fiber (KP185P)

Other more complex combinations (CKPG251P)
