3.2 LEAN AREAS

.....

 Areas where the epoxy/glass matrix is incomplete because of 

inadequate wetting of the cloth with epoxy (lean areas) are speckled 

whitish in appearance. The fully wetted laminate will have a 

consistent transparent greenish appearance. Epoxy lean areas are 

acceptable, as long as the white speckled area is less than 10% of 

the surface area. White to green ratios greater than 10% require 

rejection or repair as shown in paragraph 4.

3.3 RICH AREAS.

.....

 Resin richness primarily adds weight to the laminate. While 

some degradation of physical properties does occur, a overly wet 

(rich) layup is not grounds for rejection.

3.4 INCLUSIONS

.....

 Bristle paint brushes are used throughout the layup process. As 

a brush begins to deteriorate it will shed some bristles into the 

laminate. The bristle inclusions, up to 20 bristles per square foot, 

are not cause for rejection. Occasional inclusion of small wood chips 

or other small foreign objects is not grounds for rejection.

3.5 FIBER DISRUPTION

.....

 In all instances, it is good practice to have the glass fibers 

lying flat and without wrinkles. Major wrinkles or bumps along more 

than 2 inches of chord are cause for rejection in the wings, canard, 

and vertical fin, particularly on the upper surfaces (compression 

side). Disruptions greater than 2 inches require repairs per 

paragraph 4. 

3.6 FINISHING DAMAGE

.....

 Damage to the external structure by sanding in preparation for 

surface fill and paint can occur. Occasional sanding through the 

weave of the first skin ply is not grounds for rejection. Sanding 

through areas greater than 2 inches in diameter completely through 

the first ply or any damage to interior plies must be repaired in 

accordance with paragraph 4. A damp rag passed over the sanded 

surface will make the plies show up to determine how many plies have 

been sanded away.

3.7 SERVICE DAMAGE

.....

 Damage to the glass structure will be evidenced by cracked 

paint, or "brooming" of glass fibers. Both of these indicators are 

clearly visible. If either type of indication is present, the paint 

and filler should be sanded away, bare laminate inspected, and 

repairs made per paragraph 4 as required. Where surface damage has 

occurred it is also likely that local foam crushing has been 

inflicted. 

3.8 DELAMINATIONS

....

 Delamination of glass/epoxy lap joints is evidenced by physical 

separation of plies. These defects are easily visible and easily
