Abstract:
A modular fiber reinforced polymer (FRP) composite deck module, comprising:one or more composite hexagonal component, each hexagonal component being a hexagonal cell having a hexagonal space, made of two or more layers of multi-axial fiber reinforced fabric adhered together by a resin matrix, said layers of fabric being continuous throughout the entire shape of said hexagonal cell; one or more composite double trapezoidal components, each said composite double trapezoidal component comprising a top side; a bottom side; a first trapezoid having a first top and a first bottom; and a second trapezoid having a second top and a second bottom; wherein said first trapezoid is inverted such that said first top of said first trapezoid is adjacent to and integrated with said second top of said second trapezoid, thereby creating a center seam and an extensive bonding surface, said top side of said double trapezoidal component is integrated with said first bottom of said first trapezoid and extends beyond said first bottom of said first trapezoid, said bottom side of the double trapezoidal component is integrated with said second bottom of said second trapezoid, and made of two or more layers of multi-axial fiber reinforced fabric adhered together by a resin matrix, said layers of fabric being continuous throughout the entire shape of said composite double trapezoidal component; and a means for interlocking one said composite hexagonal component and one said composite double trapezoidal component, wherein said composite hexagonal component fits within said extensive bonding surface of said composite double trapezoidal component and under a portion of said top side of said composite double trapezoidal component that extends beyond said first bottom of said first trapezoid.
