a manual developed BY THE COMPONENT manufacturer and frequently adopted by the FAA. Blanket approval comes through the AMM and SRM.
Component Maintenance Manual (CMM)
31
defined in FAA AC 4-214. A combination of two or more materials (reinforcing elements, fillers, and composite matrix binder), identities that do not dissolve or otherwise merge completely into one identified and exhibit an interface between one another.
Composite
32
The resistance to resist the crushing force.
Compressive Strength
33
an impurity of foreign substance present in the materials or environment that affects one or more properties of the materials, particularly adhesion.
Contaminant
34
a compression damage of the core.
Core Crush
35
to change the physical properties of the material by chemical reaction, by the application of catalyst, heat and pressure, alone or in combination.
Cure
36
individual fibers woven together to produce cloth.
Fabric
37
single strands of materials used reinforcement because of its high strength and stiffness.
Fiber
38

Illustrated Parts Catalog-
39
one fabric resin layer that is bonded to adjacent layers in the curing process.
Laminate
40
persons performing a repair or alteration under parts 121 and 135. Or repair stations certificated under part 145. As used in this AC, this term includes Maintenance Repair Organization (MRO), certificated repair stations (CRS) and operators’ maintenance facilities.
Maintenance Organization (MO)
41
the alignment of the fibers to the baseline set by the manufacturer for the perpendicular component.
Orientation
42
the length of time that the resin, mixed with catalyst will be in a workable state.
Pot-Life
42
a manual which was developed by the manufacturer to cover all items not listed as minor maintenance, including instructions for structural repair, major component removal, installation and adjustment set up.
Structural Repair Manual
43
the cumulative length of time a material may be out of freezer storage,prior to curing, and still maintain the required processability characteristics and mechanical properties. Also known as a limit on the amount of accumulated out time before further action needs to be taken to ensure the raw material is still usable (also known as work life).
Out Life
43
the life span that a product will remain useful, and in FAA AC 43-214 define shelf life as the length of time a raw material may be in storage under specific conditions and still meet the requirements of the applicable material specification, also known as storage life.

ADVANTAGE OF ARAMID
- Aramid is an ideal material for use in aircraft parts that are subject to high stress and vibration. - Another important advantage is its strength-to-weight ratio; it is very light compared to other composite materials. - Flexible
61
Composite structures manufactured in this manner are sometimes referred to as ____?
sandwich construction.
61
DISADVANTAGE OF ARAMID
- The high strength of these materials can cause a problem when Aramid structures are subjected to repair. - Although it exhibits a great tensile strength , it does not have as much compressive strength eat tensile strength , it does not have as much compressive strength
62
Manufacturers construct honeycomb from the ff:
Aluminum Kevlar Carbon Fiberglass Paper Steel
63
Two most common types of core materials utilized in sandwich construction:
Honeycomb AND Nomex
64
Is a direction in which the honeycomb can be pulled apart. Pulling one side of the honeycomb that is perpendicular to the ribbon direction separates it, revealing the ribbon direction. If the pull is parallel to the ribbon, it is nearly impossible to tear the honeycomb.
