  • Process for joining elements in the manufacture of thermostructural composite material parts
    Patent number: 5310434
    Abstract: A structural connection is obtained between elements (21, 22) of the reinforcement texture to be assembled by using at least one blocking means (23). The latter is made of a fibrous texture that is compacted prior to being inserted in a corresponding lodging formed in at least one of the elements of the reinforcement texture in order to conform with the shape of the lodging. The blocking means (23) then locks itself into the lodging by relaxation of its fibrous texture, as a result of a removal of the prior compacting. The blocking means can be in the form of a dowel (23) inserted inside aligned lodgings formed in the elements (21, 22) of the reinforcement texture to be assembled, or may alternatively be part of one of the elements of reinforcement texture to be assembled.
