WHAT IS ANNEALING
ANNEALING IS A THERMAL TREATMENT USED TO SOFTEN ALUMINUM ALLOYS, REMOVING THE EFFECTS OF PREVIOUS HEAT TREATMENTS AND STRAIN HARDENING TO DEVELOP MAXIMUM FORMABILITY AND MAKE THE MATERIAL EASIER TO FORM WITHOUT CRACKING.

TYPES OF DAMAGES TO COMPOSITE MATERIALS
IMPACT: COLLISIONS FROM FOREIGN OBJECTS (TOOLBOX, MAINTENANCE STANDS, BOX TRUCKS). (01-1A-21, 3-2a)
DENTS: LARGE DIVETS IN PANELS OFTEN CAUSING CRUSHED CORE IN HONEYCOMB COMPENENTS. (01-1A-21, 3-2b)
PENETRATION: VISIBLE BY BROKEN FIBERS, MATRIX CRACKS, & DELAMINATIONS.(01-1A-21, 3-2c)
AIRSTREAM STRIPPING DAMAGE: CAUSED BY PENETRATIONS DURING FLIGHT RESULTING IN MORE DAMAGE TO OCCUR DURING FLIGHT DUE TO AIRFLOW ENTERING SMALL CRACKS AND PENETRATIONS. (01-1A-21, 3-2d)
EDGE AND CORNER: DAMAGE THAT RESULTS IN DELAMINATION OR MISSING PIECES.(01-1A-21, 3-2e)
PARTIAL THICKNESS: MOSTLY GOUGING RESULTING IN OUTER PLY SPLINTERING, BROKEN/MISSING FIBERS, AND DELAMINATIONS.(01-1A-21, 3-2f)
RESIN DAMAGE: DAMAGE TO THE MATRIX CAUSED BY HEAT, CHEMICAL ATTACK, OR EXPOSURE TO UV. (01-1A-21, 3-2g)
DISBOND: WHEN LAYERS OF COMPOSITE SEPERATE FROM EACH OTHER. (01-1A-21, 3-2h)
FLUID INTRUSION: CAUSE BY A PATHWAY IN WHICH WATER CAN GO INBETWEEN LAYERS OF COMPOSITE OR INTO THE ONEYCOMB STRUCTURE. (01-1A-21, 3-2i)
FASTENER HOLE: USUALLY GOUGING AROUND FASTENER HOLES AS CAN BE DELAMINATIONS DUE TO OVER TORQUING FASTENERS. (01-1A-21, 3-2j)

CORROSION PREVENTION PHILOSOPHY & THE BIG TAKE AWAY
***BONUS***
WHAT KIND OF DISCEREPENCY REPORT
To maximize equipment service life, it is crucial to proactively manage environmental corrosion, which is always occurring, by understanding equipment failure and utilizing control technologies.
400
HOW ARE FATIGUE CRACKS FORMED
Due to the accumulation of repeated operational stresses over time, fatigue cracks initiate and grow in aircraft structures, typically originating from points of high stress concentration like rivets and fasteners.

WHAT EFFECTS DOES NICKEL HAVE WHEN ITS ADDED TO COPPER
higher strength without loss of ductility & excellent corrosion resistance

WHAT IS THE DIFFERENCE BETWEEN PREPREG AND A STANDARD WET LAYUP
PREPREG: CONSISTS OF FIBERS THAT ARE PREIMPREGENATED WITH A PARTIALLY CURED (B-STAGED). THAT ARE CUT TO SIZED AND STACKED TOGETHER TO THEIR RESPECTIVE ORIENTATION THEN CURED IN AN AUTOCLAVE USING HEAT & PRESSURE. (01-1a-21, 2-2)
STANDARD WET LAYUP: CONSISTS OF DRY WOVEN STACKED ONTO EACH OTHER IN THE RESPECTIVE ORIENTATION CLOTH IMPREGEGNATED WITH LIQUID ADHESIVE (MATRIX) THEN CURED. (01-1A-21, 6-7e)

THE DIFFERENCE BETWEEN BONDED AND BOLTED REPAIRS.
BONDED REPAIRS: MOST COMMON REPAIR WE USE WHERE A PATCH IS BONDED TO THE DAMAGE OF A PANEL. CAN STRENGTHEN SKIN WHILE REDUCING THE INTRODUCTION OF STRESS FROM DRILLING FASTENER HOLES. DISADVANTAGES ARE MATERIALS REQUIRING SPECIAL STORAGE, HANDLING, & CURING PROCEDURES, AND A RISK OF MOISTURE EXPOSURE DURING THE CURING PROCESS. (01-1A-21, 4-3c)
BOLTED REPAIRS: QUICKER AND EASIER THAN BONDED REPAIRS BUT ARE HEAVIER, NORMALLY USED ON SKINS THICKER THAN 0.125 INCH TO ENSURE PROPER LOAD TRANSFER. PROHIBITED ON HONEYCOMB PANELS DUE TO POTENTIAL MOISTURE EXPOSURE. (01-1A-21 4-3c).

WHAT IS A SM&R CODE AND WHAT DOES EACH POSITION MEAN
A SERIES OF LETTERS IN A 6 CODE FORMAT THAT DETERMINES THE SOURCE OF THE PART, MAINENANCE ACTIONS FOR IT, RECOVERABILITY, AND SERVICE OPTION.
