Method of electrically characterizing a composite material for manufacturing an aircraft

摘要

In the method of electrically characterizing a composite material for manufacturing an aircraft, the following steps are performed: compressing two spacers against at least one test piece made of a composite material; determining an electrical resistance value for the assembly formed by the spacers and the test piece; and deducing from said value a value for the electrical resistance of the composite material.

1. A method of electrically characterizing a composite material for manufacturing an aircraft, the method comprising:
compressing first and second spacers against a first test piece made of the composite material to be electrically characterized to form: (i) a first assembly; and (ii) an interference fit between at least one of the first and second spacers and an orifice in the first test piece established by insertion of the at least one of the first and second spacers into the orifice; successively compressing, while a location of one of the first and second spacers is unchanged, the first and second spacers against a second test piece to form: (i) a second assembly; and (ii) an interference fit between at least one of the first and second spacers and an orifice in the second test piece established by insertion of the at least one of the first and second spacers into the orifice, the first and second test pieces made of the same composite material, the unchanged location shared by the first and second test pieces; determining an electrical resistance value of each of the first and second assemblies; and deducing from the electrical resistance values of the first and second assemblies an electrical resistance value of the composite material of the first and second test pieces.
