Summary

  • Adhesives (with good bonding) are a light weight material enabler

    • Allow reduced gauges and reduced # of welds or rivets – reduced costs

    • Adhesives are critical technology for composites, Mg, AHSS where brittleness is a limit

    • Adhesives provide corrosion barrier in dissimilar metal structures

  • Dec. 2007-Dec. 2008: Tasks 1-9 completed on time; Tasks 10 -15 will be completed by the end of this FY. Passed Gates 1 and 2. Gate 3 will be decided by end of FY. FY09 Milestones 1 and 2 are complete, Milestone 3 is well underway.

    • Demonstrated that strength (when adhesion is good) can be predicted quantitatively from NDE bond width and thickness measurements

    • Demonstration of NDE performance using commercial technology on steel and aluminum flat coupons

    • Demonstration of NDE performance on production bodies-in-white

    • Completed all bodies-in-white inspections

    • Demonstration of weak bond sample preparation

    • Demonstration of weak bond detection; quantification activities are underway

  • Technology transfer is well in hand

    • Commercial vendors involved in development

    • Engaged in production and related USAMP Mg and composite problems

  • Plans for Next Year - N/A, program is in final year
