摘要：A system is provided for filling a gap between adjoining coplanar first andsecond sheet members mounted on an outer surface of a common substrate and havingjuxtaposed first and second edge surfaces. A permanent gap filler member of

predetermined shape and size intended for eventual permanent reception in the gap isemployed for partially filling the gap. A temporary gap filler tool which includes asubstitute gap filler element having substantially the same predetermined size andshape of the permanent gap filler member, has an abutting surface for contiguousengagement with the first edge surface of the first sheet member when advanced to anattached position before the permanent gap filler member is mounted in the gap, aminor gap surface facing opposite said abutting surface, and means for releasablyattaching the temporary gap filler tool to the first sheet member. A minor gap is therebydefined between the temporary gap filler element and the second edge surface of thesecond sheet member. Fairing material is initially laid down as an epoxy resin slurry in aminor gap resulting between the substitute gap filler element and the second edgesurface of the second sheet member, then cured to hardened form having a substitutesecond edge surface contiguous with the minor gap surface of the substitute gap filler

element. Thereafter, the temporary gap filler is removed from the gap and the

permanent gap filler member is inserted and bonded to the common substrate resultingin the entire gap being filled.
