11513262 · 2022-11-29 · ·

A method is for manufacturing a structure obtained by stacking a substrate that is a first member as a base material, and lens arrays that are second members that are opposed to the substrate, are formed of a resin material different from the substrate, and have a shape on a surface. The method includes a surface activation step of performing an activation treatment to cause an activation state of at least one of a surface of the substrate or a surface of the lens arrays, and a bonding step of pressurizing the lens arrays at least at a temperature that is equal to or higher than a reference temperature obtained by subtracting 30° C. from a load deflection temperature of a resin material of the lens arrays, and is equal to or lower than a glass transition temperature, to closely bond to the substrate.

WEDGE-SHAPED MULTI-LAYER INTERLAYER WITH OUTER SKIN LAYERS OF VARYING THICKNESS

Multiple layer interlayers having enhanced optical and acoustic properties are provided, along with methods of making and using the same. Interlayers as described herein may include at least two outer skin layers and an inner core layer, with one of the outer skin layers having a different thickness than the other at one or more locations along the interlayer. The multi-layer interlayer may also exhibit acoustic properties and, in some cases, may have an overall wedged thickness profile. Additionally, in some aspects, interlayers and laminates formed therefrom may also provide reduced infrared energy transmission, without sacrificing acoustic and/or optical performance.
