Reinforced composite matting
DCFirst Claim
1. A reinforced composite matting for channel lining, comprising a fiber matrix held in place by a net reinforcement, said reinforcement having a bottom netting and a cuspated netting, said cuspated netting being three dimensional and defining the top and bottom of said matting, said fiber matrix being formed of a plurality of randomly oriented fibers, said fiber matrix being sandwiched between said bottom netting and said cuspated netting, said bottom netting being secured in spaced array through said fiber matrix to said cuspated netting.

Abstract
A reinforced composite matting is disclosed, to provide a foundation for the development of vegetation to stabilize the channel surface, as a cost effective and environmentally friendly alternative to rip rap or concrete channel lining. The reinforced composite matting is formed of a bottom netting, a cuspated netting having ridges and troughs extending across the width of the cuspated netting, with the troughs substantially adacent to the bottom netting, and a top netting substantially adacent to the ridges of the cuspated netting. A fiber matrix, preferably of strands of coconut fibers is disbursed between the bottom netting and the cuspated netting, and the bottom netting, fiber matrix, cuspated netting and top netting are secured together, preferably with thread, to form the reinforced composite matting of this invention.

20. A reinforced composite matting for channel lining, comprising a fiber matrix held in place by a net reinforcement, said reinforcement having a bottom netting defining a grid of apertures, a cuspated netting defining a grid of apertures, said cuspated netting apertures having a plurality of alternating ridges and troughs extending in substantially parallel relation, said fiber matrix being sandwiched between said bottom netting and said cuspated netting, said bottom netting being secured in spaced array through the fiber matrix in close proximity to said troughs to said cuspated netting, and a top netting defining a grid of apertures, said top netting being secured in spaced array to said ridges of said cuspated netting.

21. A three phase reinforced composite matting which traps sediment, mulch, leaves and thatch to expedite natural soil in-filling and plant root entanglement for improved erosion control as a channel lining, comprising a fiber matrix formed of a plurality of randomly oriented fibers held in place by a net reinforcement, said reinforcement having ultra-violet stabilized bottom netting defining a grid of apertures, and an ultra-violet stabilized cuspated netting, said cuspated netting having a plurality of alternating ridges and troughs extending in substantially parallel relation, said fiber matrix being sandwiched between said bottom netting and said cuspated netting, said bottom netting being secured in spaced array through the fiber matrix in close proximity to said troughs of said cuspated netting, wherein said bottom netting acts as a structural support in retention of said fiber matrix to eliminate fiber loss under high velocity channel flow, said cuspated netting forms a three dimensional structure in conjunction with said fiber matrix for trapping sediment and thatch and expediting natural soil in-filling and root reinforcement, said fiber matrix provides temporary and long term erosion control and mulch accumulation for the channel surface by retaining underlying soil, seed and moisture, said cuspated netting also contains in-filled soil leaves and thatch, ultimately forming a complete three dimensional structure providing a permanent matrix for plant root entanglement and reinforcement.
