Systems and methods of forming fiber reinforced polymer (FRP) composites with electrostatic dissipative properties are described herein. The FRP composite is bonded to a surface and integrates a grounding system to dissipate electro-static energy, thus eliminating the potential risk of explosion. The system can be used for structures that require reinforcement and that are susceptible to electro-static explosions.

Structurally enhanced preformed layers of multiple rigid unidirectional rods are constructed and arranged for use in fabricating load-bearing support structures and reinforcements in a variety of composite components, e.g. wind turbine blades. Individual preform layers include multiple elongate unidirectional strength elements or rods arranged in a single layer along a longitudinal axis of the preform layer. Individual rods include aligned unidirectional structural fibers embedded within a matrix resin such that the rods have a substantially uniform distribution of fibers and high degree of fiber collimation. The relative straightness of the fibers and fiber collimation provide rods and the preform layers with high rigidity and significant compression strength. A plurality of rods are loosely attached, e.g. knitted, together with a coupling that allows for each rod to be axially displaced, e.g. slideable, relative to another rod.
