    Abstract: In blown film installations, it is known to provide longitudinal stretching of the produced double layer film strip downstream of the draw-off, more precisely downstream of the reversing unit and upstream of the winder. It is also known to stretch the down-drawn film, wherein the film must then be preheated owing to the long cooling path from the draw-off. According to a first feature, the present invention specifies warming the film above the draw-off and then treating it mechanically. The film can thereby be brought with only little energy from a first level of warmth to a temperature level at which it can easily be worked. According to a second feature, the invention specifies providing a tractive force breakdown brake.

    Abstract: A method and apparatus for fabricating a composite part, such as a fuselage or internal stiffener, with a shape memory polymer (SMP) apparatus usable as both a rigid lay-up tool and a bladder. The SMP apparatus may be heated until malleable, shaped, and then cooled in a desired rigid tool configuration. For example, cavities may be formed into the SMP apparatus for nesting components therein to co-bond or co-cure with the composite part. Next, composite material may be applied onto the SMP apparatus and then placed into a rigid external tool and heated to composite cure temperatures at which the SMP apparatus is malleable. A pressure differential may be induced which urges the SMP apparatus to compress the composite material against the rigid external tool. When the composite material is cured, the SMP apparatus may be urged away from the cured composite material and removed from within the composite part.

  • Patent number: 8945455
    Abstract: A support apparatus and method for providing structural support to a shape memory polymer (SMP) apparatus during fabrication of composite parts. The support apparatus may comprise an adjustable, rigid structural member and a plurality of SMP support components transitionable between a rigid and malleable state and fixed to an outer surface of the rigid structural member. The rigid structural member may extend in at least one cross-sectional dimension toward the SMP apparatus, pressing the SMP support components, in their malleable state, against the SMP apparatus. The SMP support components may thereby conform to a first surface of the SMP apparatus, then return to their rigid state while pressed against the SMP apparatus, thus providing a rigid load path between the SMP apparatus and the rigid structural member. Then composite material may be applied to a second surface of the SMP apparatus, opposite of the first surface.

  • Publication number: 20140318591
    Abstract: Self-corrugating laminates useful in the manufacture of thermoelectric devices are disclosed. The laminates include an upper and a lower shrinkable film layer and a non-shrinkable core with a thermoelectric pattern formed thereon bonded between said upper and lower shrinkable film along bond lines arranged parallel, substantially parallel, radially, or annularly. The bond lines that bond the upper shrinkable film layer to top surface of the nonshrinkable core are staggered relative to the bond lines that bond the lower shrinkable film layer to the bottom surface of the non-shrinkable core such that upon shrinkage of the shrinkable film layers, structural corrugations are formed in the non-shrinkable core. Thermoelectric modules or devices and methods for forming them from the self-corrugating laminates are also described.

  • Publication number: 20140303287
    Abstract: A composition comprising thermoset polymer, shape memory polymer to facilitate macro scale damage closure, and a means for molecular scale healing is disclosed; the composition has the ability to resolve structural defects by a bio-mimetic close-then heal process. In use, the shape memory polymer serves to bring surfaces of a structural defect into approximation, whereafter use of the means for molecular scale healing allowed for movement of the healing means into the defect and thus obtain molecular scale healing. The means for molecular scale healing can be a thermoplastic such as fibers, particles or spheres which are used by heating to a level at or above the thermoplastic's melting point, then cooling of the composition below the melting temperature of the thermoplastic. Compositions of the invention have the ability to not only close macroscopic defects, but also to do so repeatedly even if another wound/damage occurs in a previously healed/repaired area.

  • Publication number: 20140110880
    Abstract: A thermoplastic elastomer compound is disclosed having a high strain recovery rate and a high strain fixity rate to provide shape memory, preferably manageable shape memory. One type of thermoplastic elastomer compound is comprises a maleated styrenic block copolymer and polycaprolactone to achieve the shape memory. A second type of thermoplastic elastomer compound comprises styrene-ethylene/butylene-styrene and a paraffin wax having less than about 0.5% oil content. Shape modes of articles made from the thermoplastic elastomer compound can be altered by at least one thermo-mechanical event to cause deformation of the compound from a first shape to a second shape with retention of the compound in the second shape for any reasonable time interval.

  • Publication number: 20140035192
    Abstract: Tubular casting processes, such as dip-coating, may be used to form substrates from polymeric solutions which may be used to fabricate implantable devices such as stents. The polymeric substrates may have multiple layers which retain the inherent properties of their starting materials and which are sufficiently ductile to prevent brittle fracture. Parameters such as the number of times the mandrel is immersed, the duration of time of each immersion within the solution, as well as the delay time between each immersion or the drying or curing time between dips and withdrawal rates of the mandrel from the solution may each be controlled to result in the desired mechanical characteristics. Additional post-processing may also be utilized to further increase strength of the substrate or to alter its shape.

  • Patent number: 8641951
    Abstract: The invention relates to a method for producing a programmed shape memory polymer, which assumes a first temporary shape and at least two additional stored thermally activatable shapes, namely at least one second temporary shape and a permanent shape, with the steps of: (a) providing a shape memory polymer which has at least two switching segments (A, B), which through phase segregation each form a switching phase having each a corresponding transition temperature (TtransA, TtransB), (b) deforming the shape memory polymer into a shape corresponding to the first temporary shape at a temperature above the upper transition temperature (TtransA), and (c) cooling to a temperature below the lower transition temperature (TtransB) by fixing the first temporary shape. The method of the invention provides a one-step programming method for a triple-shape plastic material.
