Abstract
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.

A reinforcing and electrostatic dissipative (ESD) composite system (100) comprising:
- a. a fiber reinforced polymer (FRP) composite (110) for strengthening and structural reinforcement, said FRP composite comprising:
- i. a base coating (112) configured to be applied on a surface (15) of a structure (10);
- ii. a reinforcing ply stack (120) disposed on the base coating (112), wherein the ply stack (120) comprises one or more reinforcing fabric plies (122), each fabric ply (122) being layered atop another fabric ply (122) to form the ply stack (120), wherein each fabric ply (122) comprises a plurality of linear pockets (124) aligned in parallel, wherein each pocket (124) is stitched lengthwise to its neighboring pockets (124) at a pocket seam edge (125);
- and a fiber tow (126) comprising a plurality of filaments (128) collected into a bundle, wherein the fiber tow (126) is disposed lengthwise in each pocket (124);
- iii. a polymer resin composition (114) applied on the ply stack (120) and saturating each fabric ply (122);
- and
- iv. a top coating (116) disposed on the saturated ply stack (120);
- b. a conductive filler material (130) disposed in the top coating (116) of the FRP composite;
- c. a conductive network (140) of wires or tape juxtaposed between the saturated ply stack (120) and the top coating (116) with the conductive filler material (130);
- and
- d. a grounding component (160) connected to the conductive network (140) via a connection clip (150);
- wherein when the system (100) is disposed on the surface of structure, the FRP composite (110) is effective for strengthening and reinforcing the structure (10), wherein the conductive filler material (130) is effective for dissipating static from the structure (10) and the FRP composite (110) to the grounding component (160) via the conductive network (140), thereby reducing a risk of static ignition.
