Abstract
This paper addresses three separate composite repair issues currently being investigated at the Defence Research Establishment Pacific (DREP) in support of Canada's CF-18 aircraft. First, the problem of skin/core debonding that can occur during elevated temperature bonded repairs of honeycomb sandwich structure is discussed and results of tests which help to quantify the role played by bondline degradation are presented. Next, the final development phase of an on-going effort to establish a reliable and effective means of repairing delamination damage is reported. In particular, the design of a resin injection device and a series of tests to evaluate its performance are described. Finally, a battle damage repair issue, namely the advantages and disadvantages of cleaning up the damaged composite material found around entry and exit holes created by live fire, is discussed. Test data is presented which compares the different consequences under tensile and compression loading.
