However, beyond the cost issues, the major obstacle that preventing the extended use of GFRP materials in civil engineering especially grating is lack of information and uncertainty associated with the due to no consensus guidelines for the design of GFRP grating comparable to the traditional construction materials.
It is a continuous, semi-automated process for manufacturing composite materials.
