An aerial work platform assembly is provided, comprising a platform shaft retaining assembly; a mounting bracket connected to the platform shaft retaining assembly; and a platform connected to the mounting bracket; wherein the platform shaft retaining assembly, mounting bracket, and platform are constructed from the same or differing composite materials comprising a fabric-reinforced resin. Optionally, the fabric-reinforced resin includes a preform fabric having a conformable three-dimensional weave, and the resin is a dielectric resin selected from either epoxy, epoxy vinyl ester, vinyl ester, polyester, or phenolic.

We claim: 1. An aerial work platform assembly, comprising: a) a platform shaft retaining assembly; b) a mounting bracket connected to said platform shaft retaining assembly; and c) a platform connected to said mounting bracket; wherein said platform shaft retaining assembly includes two concentric apertures for installation of a pivot shaft therein; the mounting bracket having an upper gusset member and a center gusset member that are bonded together and that include horizontal portions to which the pivot shaft is bonded; upper and lower platform pins; a valve bracket; a platform bracket; and upper platform pins that provide for pivoting on a lower platform pin and tilting down of the platform thereby, and wherein the platform shaft assembly, the mounting bracket, the upper and lower platform pins, the valve bracket, and the mounting bracket are constructed in a redesigned manner and are non-conductive and constructed from a three-dimensional integrally and unitarily formed orthogonal woven, multiaxial, or braided preform infused with resin to form a composite material that resists delamination comprising a first fabric-reinforced resin, and wherein the aerial platform assembly is insulated and non-conductive and includes substantially no metal components, wherein the preform is unitarily and integrally constructed by three (3) independent, interlacing, non-crimped yarn systems, the preform providing for no delamination of the composite formed therefrom. 2. The assembly of claim 1, wherein said mounting bracket is non-conductive and is constructed from a second fabric-reinforced resin. 3. The assembly of claim 1, wherein said platform is non-conductive and is constructed from a third fabric-reinforced resin. 4. The assembly of claim 1, wherein said fabric-reinforced resin includes a preform fabric having a conformable three-dimensional weave. 5. The assembly of claim 1, wherein said resin is a dielectric resin selected from the group consisting of epoxy, epoxy vinyl ester, vinyl ester, polyester, and phenolic. 6. An aerial work platform assembly, comprising: a) a platform shaft retaining assembly that includes two concentric apertures for installation of a pivot shaft therein; b) a mounting bracket connected to said platform shaft retaining assembly; and c) a platform connected to said mounting bracket; wherein the mounting bracket further includes an upper gusset member and a center gusset member that are bonded together and that include horizontal portions to which the pivot shaft is bonded; upper and lower platform pins; a valve bracket; a platform bracket; and upper platform pins that provide for pivoting on a lower platform pin and tilting down of the platform thereby, and wherein the platform shaft assembly, the mounting bracket, the upper and lower platform pins, the valve bracket, and the mounting bracket are constructed in a redesigned manner, and are non-conductive and constructed from a composite material comprising a first fabric-reinforced resin and include substantially no metal components, and wherein the aerial work platform assembly is completely insulated and non-conductive, the first fabric-reinforced resin including a preform fabric that is unitarily and integrally constructed by three (3) independent, interlacing, non-crimped yarn systems that provide for no delamination of the composite formed therefrom. 7. The assembly of claim 6, wherein said mounting bracket is non-conductive and is constructed from a second fabric-reinforced resin. 8. The assembly of claim 6, wherein said platform is non-conductive and is constructed from a third fabric-reinforced resin. 9. The assembly of claim 6, wherein said resin is a dielectric resin selected from the group consisting of epoxy, epoxy vinyl ester, vinyl ester, polyester, and phenolic. 10. An aerial work platform assembly, comprising: a) a platform shaft retaining assembly; b) a mounting bracket connected to said platform shaft retaining assembly; and c) a platform connected to said mounting bracket; wherein said platform shaft retaining assembly is non-conductive and includes substantially no metal components and is constructed from a composite material formed from a non-random fiber matrix that resists delamination, the composite material comprising a first fabric-reinforced resin, and wherein the aerial work platform assembly is completely insulated and non-conductive; the fabric-reinforced resin having a conformable three-dimensional construction, wherein the preform fabric is unitarily and integrally constructed by three (3) independent, interlacing, non-crimped yarn systems, the preform providing for no delamination of the composite formed therefrom. 11. The assembly of claim 10, wherein said platform shaft retaining assembly is non-conductive and is constructed from a second fabric-reinforced resin. 12. The assembly of claim 10, wherein said mounting bracket is non-conductive and is constructed from a third fabric-reinforced resin. 13. The assembly of claim 10, wherein said resin is a dielectric resin selected from the group consisting of epoxy, epoxy vinyl ester, vinyl ester, polyester, and phenolic. 14. An aerial work platform assembly including composite components for providing a lightweight, strong structure that is non-conductive, the composite components consisting essentially of: a platform shaft retaining assembly including two concentric apertures for installation of a pivot shaft therefrom; a platform mounting bracket having an upper gusset member and a center gusset member that are bonded together and that include horizontal portions to which the pivot shaft is bonded; upper and lower platform pins; a valve bracket; and upper platform pins that provide for pivoting on the lower platform pin and tilting down of the platform thereby, wherein these components are formed of non-conductive composite materials, including 3-D woven preforms that are unitarily and integrally formed and later infused with resin to form the composite materials, wherein the preform are unitarily and integrally constructed by three (3) independent, interlacing, non-crimped yarn systems, the preform providing for no delamination of the composite formed therefrom, and wherein these components do not include metal or conductive material.
