#CMT# #/CMT# The method involves replacing a portion of one of external shell by a new portion (6). A rigid key form (8) is set on a new portion and around the new portion. The key form is supported on the structure in composite material and the new portion is hardened. Other shell (3) is pierced till an inner core (1) and air contained in the core is drained before hardening. #CMT#USE : #/CMT# Used for repairing a composite material structure in an apparatus e.g. transport equipment, rail equipment, maritime equipment, or aeronautic equipment, on shell of boats or on fairing, leading edge of aerofoil, aileron and radome of aircraft. #CMT#ADVANTAGE : #/CMT# The shell is pierced till the inner core and the air contained in the core is drained before hardening, thus permitting to guaranty the sealing to the new portion on an internal core in an efficient manner, and hence improving the appearance of the structure, while preserving the radioelectric transparency during painting and ensuring rapid repairing. The surface on the new portion is made up of polytetrafluoroethylene so as to ensure easy demolding after hardening. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a composite material structure repairing method. 1 : Inner core 3 : Outer shell 6 : New portion 8 : Rigid key form 11 : Vacuum pump #CMT#POLYMERS : #/CMT# The surface on the new portion is made up of polytetrafluoroethylene. |
