Abstract:
A modular fiber reinforced polymer (FRP) module that interlocks with other similarly designed modules. Specifically, each FRP module has a female, receiver, end and a male, inserter, end such that the inserter of a first FRP module interlocks with, or “snaps into” or “slids into,” a receiver of an adjacent second FRP module. Once interlocked, the two connected FRP modules are further secured by either adhesive and/or thermal connections. An FRP module is made of multiple layers of multi-axial fiber reinforcement and a resin matrix, the layers being continuous throughout the entire shape of the module. An overlay may be placed over the top face of one or more FRP modules joined together to provide a uniform surface. In addition, one or more exterior FRP composite laminates, grids, plates or fabrics may be bonded continuously to the top face. In certain embodiments, one or more of the internal spaces of a FRP module may be filled with a filler for thermal insulation, noise reduction insulation, or a strength and stability enhancement of the FRP module.
