Abstract
The test method employed uses a cylindrical solid aluminum pin having a first stem portion and a threaded second portion separated by a middle necked down portion. The test pin threaded portion is inserted into a flowable adhesive such as an epoxy inside a joining pin located in a hole through abutting honeycomb panels and the epoxy is allowed to cure. A force is exerted on the first portion of the test pin until either the test pin separates at the necked down portion or the test pin is dislodged from the joining pin. In the latter case, the test indicates an improper mixture or a poor curing of the adhesive.
