    摘要： A single piece co-cured composite wing is disclosed. The wing has a flying surface and structural members. In one embodiment the structural members may be a plurality of spars. The spars may have various shapes to increase the buckling strength. The spars may be wave shaped, such as a sinusoidal shape. The flying surface and the structural members are co-cured in order to form a single piece, integral wing structure. A process for manufacturing a single piece co-cured wing is also disclosed. The process may include laying out composite sheets for the flying surface of the wing. Then, the composite material of the spars is arranged around a plurality of pressurizable forms. Finally, the composite material is cured in a clamshell frame.

    摘要： Method of retarding age embrittlement of polyester comprising heat treating the polyester after preparation by cooling below 90 °C and then heating at 90 °C to 160 °C within 24 hours of preparation, and a polyester composition in which ageing is substantially retarded compared to the non-heat treated polyester. The invention encompasses the polyester composition which has been subjected to the method.

    摘要： A method of making a dilatation balloon with a high percentage of the maximum tensile strength of the balloon material from a thin wall parison of a biaxially orientable polymer, such as polyethylene terephthalate (PET). A reverse temperature gradient (decreasing going from the inner to outer diameters) in applied across the sidewall of the parison by flowing a heated fluid through the parison and then sealing one end of the parison and expanding with a heated expansion fluid. Decreases in wall thickness and/or increases in burst strength across the wall can be achieved.
