    Abstract: This invention is concerned with means for detecting potential fracturing, such as stress fractures, or damage to, a fibre based structure, by incorporating either hollow fibres containing coloured fluids, or solid fibres, or hollow fibres containing coloured fluids or fluids, which are capable of changing their visual appearance when exposed to external forces, and/or by incorporating fibres within the structure which can change a property such as electrical resistance, capacitance or inductance so that there is an indication whenever and wherever and the extent when a fracture occurs. Where coloured fluids are used, detection is by leakage of the fluid around the fracture. Where colour changing fluids are employed, detection is by observation of change of colour of the fluid. Different fluids can be used for different levels in the strata of tubes in the structure and where these are embedded within the structure, they can be observed where the fibres emanate from the body of the structure. Where fibres are incorporated into the structure that rely on electrical properties to sense a fracture, these fibres may be solid and formed from electrically conductive material and may be coated with such material. Alternatively, though used together with solid fibres, hollow fibres may be used where those hollow fibres contain and/or are coated with electrically conductive material. Appropriate detector means are associated with these fibres to detect the occurrence of a fracture.

    Abstract: A method of calibrating pressure sensitive paint is provided comprising the steps of: illuminating the paint under a range of pressures and temperatures; measuring the intensity of light emitted by the paint following each illumination thereby measuring decay curves; and performing a curve fit of the decay curves to determine characteristic constants. These constants can then be used to generate a model of decay curves and a polynomial relating pressures and temperatures for ratios of intensities over gated areas of the model decay curves can be calculated. Pressure determination at the calibrated paint can then be performed by illuminating the paint, measuring the intensity of light emitted by the paint over two of the gated areas, determining the , ratio of the gated area intensities and finally determining the pressure and/or temperature from the polynomial using the determined ratio of the gated area intensities.
