ACTIVATED THREAD CURING OF LIQUID ADHESIVES

摘要

Structures and methods for providing a liquid adhesive between substrates of a composite structure are described. Methods include providing a liquid adhesive having a thread disposed therein between two substrates of a composite structure. In some embodiments, the thread has a fixed diameter which acts to provide a consistent gap between the two substrates. In some embodiments, the thread is configured to be activated during the assembly process to facilitate curing of the liquid adhesive. In some embodiments the thread is configured to be activated after the composite structure is formed to facilitate separation of the two substrates and disassembly of the composite structure. The thread can be made of a conductive or non-conductive material. In some embodiments, the thread is activated by passing a voltage through the thread to heat the thread. In some embodiments, the thread is activated by passing ultraviolet light through the thread.

1. A method of forming a composite structure having a first substrate and a second substrate, comprising:
dispensing a liquid adhesive conglomerate comprising a compressible liquid adhesive portion and a rigid thread structure incorporated therein onto a portion of a first surface of the first substrate, the rigid thread structure having a diameter that remains fixed, the rigid thread structure configured to be activated to cure a liquid adhesive; aligning a second surface of the second substrate with respect to the portion of the first surface; forming a gap between the first and second substrates by applying a pressure to press the first and second surfaces together, the gap between the first and second substrates having a distance in accordance with the diameter of the rigid thread structure; and during the pressing, curing the liquid adhesive by activating the rigid thread structure, wherein the gap remains in accordance with the diameter of the rigid thread structure after the liquid adhesive is cured.
