16
Q

Known as finishing tape, applied after the fabric is installed

A

SURFACE TAPE

17
Q

Used to lace the fabric to the wing ribs. Must be strong and applied as directed to safely transfer in-flight loads from the fabric to the ribs

A

RIB LACING CORD

18
Q

Used on wing ribs before the fabric is installed. Applied spanwise and alternately wrapped around a top rib cap and then a bottom rib cap progressing from rib to rib until all are braced.

A

RIB BRACING TAPE

19
Q

Used to create reinforced drain holes in the aircraft fabric. Made of aluminum or plastic.

A

GROMMETS

20
Q

Provide a stable rim around an area of fabric that can be cut to allow viewing of the structure underneath

A

INSPECTION RINGS

21
Q

Final preparation procedure, a treatment that works with the adhesive and first coats of fabric sealant.

A

PRIMER

22
Q

Utilize special fabric cement to attach the fabric to the airframe. In addition to good adhesion qualities, flexibility, and long life, fabric cements must be compatible with the primer and the fabric sealer

A

FABRIC CEMENT

23
Q

Surrounds the fibers in the fabric with a protective coating to provide adhesion and keep out dirt and moisture

A

FABRIC SEALER

24
Q

Contains solid or chemicals that are included to block UV light

A

FILLER

25
Q

Give the aircraft its final appearance

A

TOPCOATS

26
Q

Tightens and stiffens fabric stretched over airframes, which renders them airtight and weatherproof

A

AIRCRAFT DOPE

27
Q

Used to bond fabric to the structure in much the same way as glue. Quite flammable
Bonds to the fibers of the fabric and to the structure better than butyrate dope.

A

NITRATE DOPE

28
Q

Most popular dope products used today. More difficult to ignite than nitrate and burns much more slowly.

A

BUTYRATE DOPE

29
Q

Accelerates a chemical reaction

A

CATALYSTS

30
Q

Solvent or mixture of solvents added to a product to give it the proper consistency for application

A

THINNER

31
Q

Multiple flat sections of fabric are trimmed and attached to the airframe

A
