    摘要： A drill template includes a vacuum housing with a skirt having a CAD-formed contact surface formed to an exact fit with a mold line surface of a structure. The drill template includes at least one drill guide bushing extending through the vacuum housing from a top surface to an interior surface of the vacuum housing; a vacuum port integral to the vacuum housing; and at least one index hole for positioning and aligning the vacuum housing on the structure. Index holes extend from the top surface through to the CAD-formed contact surface of the vacuum housing. A CAD-formed edge of part locator is formed according to a CAD solid model of the aircraft fuselage and fits to a precise location of the structure for precisely positioning the template on the structure. A vacuum port provides vacuum to the interior of the vacuum housing for removing drilling debris and dust.

    摘要： The laminar article of the invention comprises a mixture of a polyolefin matrix with a barrier resin of polyethylene-vinyl alcohol copolymer and a compatibilizer selected from an ethylene-ethylenically unsaturated carboxylic acid copolymer such as ethylene methacrylic acid or ethylene acrylic acid, ethylene vinyl acetate, polyethylene vinyl alcohol or mixtures thereof. A process is also claimed for preparing a laminar article with multiple thin, overlapping layers, comprising preparing a melted heterogeneous blend of a polyolefin, an ethylene-vinyl alcohol copolymer, and the above compatibilizer; extending the body of the melt; and cooling the extended body to below the melting point of the polyolefin.
