Problems solved by technology

However, glass can be brittle and prone to cracking and failure (for example, when impacted along an edge)
Also, direct adhesion to glass substrates for polymer resins can be difficult
Additives, surface treatments and / or adhesives can be used in an effort to improve adhesion, however the interface between the glass and polymer resin can still be a weak point where separation can occur

Embodiment

[0113] A set of multi-span bending tests was performed to evaluate the effectiveness of the A-B-A structure. will consist of a single layer of 0.25mm TencateCETEX TC 925 FST outer layer (type 7581 E-glass fabric in a polycarbonate matrix with 50vol% loading, 0.24mm thick) and 0.50mm unreinforced LEXAN TM Thin-walled sandwich composites consisting of 8B35 core layers were laminated in a vacuum-assisted press. The total laminate thickness was 1.00mm and the center ply / outer ply thickness ratio was 0.50. The nominal bending size is 25mm×100mm. Samples were tested over four spans to eliminate geometric and shear related effects. Samples were also taken in three directions to test for anisotropy. Specifically, the bent samples were machined in directions corresponding to the "warp", "weft" and "bias" of the outer layer. TC 925 FST uses 7581E-glass fabric. This is an 8 warp satin with a relatively "balanced" construction. Orientational samples were prepared to aid in the unde...

Abstract

An article of manufacturing can comprise a mold insert comprising: a cap substrate having a first surface and a second surface; an adhesive coupled to a portion of the second surface of the cap substrate; a base substrate having a first surface and a second surface, wherein the first surface of the base substrate is coupled to the adhesive, wherein the adhesive is disposed between the second surface of the cap substrate and the first surface of the base substrate; and a polymeric resin attachment, wherein the polymeric resin attachment is coupled to a portion of the second surface of the base substrate, wherein the polymeric resin extends along an edge of the base substrate, and along an edge of the cap substrate.

Description

Background technique [0001] An electronic device may have a control panel where a user may interact with the device. The control panel may have layers that may include a display source, a touch-sensitive device, and / or a cover window disposed over the touch-sensitive device. The control panel can display information to the user and interpret the user's physical contact with the panel surface. A user can interact with the device by touching the surface of the cover window. Images can be projected from a display source through the panel. The cover window can include glass that can provide a transparent protective layer and can cover the touch sensitive device. Glass may be transparent and may be abrasion resistant, and thus may be suitable for use as a cover window. However, glass can be brittle and prone to cracking and failure (eg, when impacted along an edge). Additionally, direct adhesion to glass substrates can be difficult for polymeric resins. Additives, surface tre...
