Detachable Fastener Installation (patent pending)

Fasteners used in aircraft manufacture to attach parts and install wire and cables are bonded using epoxy adhesives to avoid stress concentration and material fatigue of structural parts.

Aerospace grade thermoset adhesives require a long curing time with full adhesive cure at room temperature takes 3 to 4 days. Epoxy adhesive is difficult to remove while making repairs. Bonding preparation on a large composite based structural component can be risky work if the structure is accidentally damaged during prep work.

Kubota Research has developed a high speed fastener attaching and detaching method for manufacture and repair, using MemBond™ adhesive and P-Wave™ radiation processing. The process time to attach and detach a MemBond™ fastener is less than 30 seconds and can be done without concern of damage to the substrate.
