1. A method for fabrication of a wind turbine blade comprising:
forming a composite wind turbine blade structure within a mold, wherein forming includes
dispensing a resin throughout at least a first portion of the composite wind turbine blade structure;
applying a surface treatment to at least the first portion of the composite wind turbine blade structure, the surface treatment includes abrasion resulting in particles of various sizes and increasing the surface area of the first portion of the composite wind turbine blade;
providing a Fourier Transform Infrared (FTIR) spectrometer;
irradiating at least the first portion of the composite wind turbine blade structure with infrared light, wherein the irradiation is applied to the particles of various sizes and the first portion of the composite wind turbine blade; and
determining an amount of the infrared light absorbed in at least the first portion of the composite wind turbine blade structure to measure the chemical bond of the composite wind turbine blade structure.
