摘要:
The invention relates to a Method for manufacturing an optical article comprising the following steps: a. Providing a first substrate (14) with a main surface, b. Depositing a second substrate (16) on said main surface by means of an adhesive layer (15) so that the space between the first substrate (14) and second substrate (16) is filled by said adhesive layer (15), c. Curing the adhesive layer (15) to induce a polymerization of the adhesive layer (15), Wherein a tension step takes place after steps a. and b., and before step c., said tension step consisting in applying symmetrically a tension, preferentially with a central symmetry, preferentially a radial isotropic tension or an ortho-distributed symmetrical tension, on the edges of the second substrate (16) sensibly in a tension plan parallel to a plan representative of the main surface.

A stretch laminate having a first substrate is adhesively attached to an elastic film. The adhesive is applied in a continuous manner to the substrate in a first tack down region which is disposed proximate to an end of the stretch laminate. The adhesive is applied as a plurality of adhesive stripes in an activation region which is interior of the first tack down region. The adhesive stripes have a width and a distance between adjacent adhesive stripes. The ratio of stripe width to distance between the adhesive stripes is in the range of less than about 1 or greater than about 0.33.

To acquire a stretchable sheet having air permeability due to the presence of through-holes, with no hole formed through outer layers. There are provided: interposing a resilient film (30) that stretches and contracts, in a stretched state between a first sheet layer (21) having no elasticity and a second sheet layer (22) having no elasticity; and joining the first sheet layer (21) and the second sheet layer (22) together with a number of joints directly or through the resilient film 30 by melting the resilient film (30) with ultrasonic fusion energy applied by a thermal fusion device from the outside of the first sheet layer (21) and the outside of the second sheet layer (22) to a number of joint regions with intervals, during the interposing. A through-hole (31) is formed through at least a boundary portion in a direction of the stretching between the resilient film (30) and each of joints (40), with the first sheet layer (21) and the second sheet layer (22) retained, no hole being formed over the entirety of each of the joint regions.

A method of producing an insulated corrugated fiber cement sheet (1) is described. The method comprises providing a cured corrugated fiber cement sheet, shrinking the cured corrugated fiber cement sheet and adhering a thermal insulation panel (2) having recesses (3) such that these engage with the undulations (4) of the fiber cement sheet (7) while leaving openings (5) for acclimatization. Disclosed is also an insulated corrugated fiber cement sheet (1), a thermal insulation panel (2) for producing such an insulated corrugated fiber cement sheet, and a kit of parts comprising the fiber cement sheet (7) and the thermal insulation panel (2).
摘要:
Aspects of the present invention relate to systems and methods of integrating dynamic materials into articles for adjustable physical characteristics (e.g., aesthetic, functional). For example, in response to a human's body heat, a dynamic material may change shape to allow additional permeability in an article of clothing. Similarly, in response to the presence of moisture, an article of clothing may close a vent to prevent the introduction of rain into an internal portion of the article. The shape changing material may change shape that merely affects a feature formed by the shape changing material. Additionally, it is contemplated that the shape changing material may change shape that affects a geometric structure of the article as a whole (e.g., protrusions, dimples, vents, etc.).
摘要:
System for forming a micro-truss reinforced structural member (10, 12) which includes a first collimated light source (14) and a reservoir (20) containing a volume of photo-monomer resin (18) wherein the first collimated light source (14) is positioned spaced apart from the photo-monomer resin (18). The system further includes a first face sheet structure (24) defining at least one bore (26) which extends through the first face sheet structure (24) wherein a portion of the first face sheet structure is positioned under a surface of the volume of photo-monomer resin such that photo-monomer resin (18) is positioned within the bore (26).
