Vacuum Bagging of Thermosetting Composite Repairs

Scope:

This Aerospace Recommended Practice (ARP) describes methods of vacuum bagging, a process used to apply pressure in adhesive bonding and heat curing of thermosetting epoxy and polyester matrix fabrications for commercial aircraft composite parts. If this document is used for the vacuum bagging of other than thermosetting epoxy and polyester materials, the fitness for this purpose must be determined by the user.

The methods shall only be used when specified in an approved repair document or with the agreement of the Original Equipment Manufacturer (OEM) or regulatory authority.

The purpose of this ARP is to provide a set of standard methods for the bagging of thermosetting composite materials that may be referenced in repair documents produced by airlines or airframe and engine manufacturers. It is intended that this ARP be one of a number of ARPs that will cover other aspects of the techniques required to perform composite repairs.

Rationale:

CACRC AIRWORTHINESS TASK GROUP REQUESTED A REVIEW TO INCLUDE AN ADDITIONAL BAGGING PROCEDURE.THE DRAFT FORMAT WILL ALLOW US TO REVISE IT IF NECESSARY DURING CACRC MEETING
