S GLASS
S Glass uses a unique chemical fommulation which results in a stronger, tougher, and stiffer fabric than E Glass. S Glass is approximately 25% stronger than E Glass. One ply of S Glass can replace several plys of E Glass resulting in a considerably lighter wing or fuselage structure.
1.4 Oz. / Sq. Yd. Plain Weave
The lightest weight S Glass available. The high strength to weight ratio makes this fabric an ideal candidate for reinforcement of hand launch gliders and aircraft with light wing loading.
3.7 Oz. / Sq. Yd. Satin Weave
Can be used to make wing skins for large aircraft and fuselage bodies.
Kevlar®
Kevlar® is a high strength, high stiffness, light weight Aramid fiber material. Kevlar® can offer both a significant weight savings and improved stiffness in comparison with fiberglass. It addition, it offers superior abrasion and impact resistance. Since polyester resin does not bond well with Kevlar®, we recommend laminating with EZ-Lam Epoxy Resin which has excellent wetting characteristics.
1.7 Oz. / Sq. Yd. Plain or Satin Weave
The 1.7 Oz. Kevlar® can be used to replace 3 Oz. or 4 Oz. glass for foam wing skins. It can also be used to build tougher and stiffer fuselages or boat hulls.
4.8 0z./ Sq.Yd.
This satin weave Kevlar® is a high strength woven fabric used on 1/4 scale fuselages and wing skins.
GRAPHITE
Woven graphite fabric is a high performance structural material with three times the strength, five times the stiffness of fiberglass, and a very low density. ACP offers the following selection of bidirectional woven graphite fabrics:
2.9 0z./Sq.Yd.
Consists of 1K carbon strand (tow) woven in a 12 1/2 x 12 1/2 strands per inch count yielding a somewhat open plain weave fabric. The lightest woven carbon fiber fabric available. Can be used for wing skins when vacuum bagging wings where weight is a concern.
3.5 Oz./Sq.Yd.
Consists of 1K carbon strand (tow) woven in a 24 x 24 strands per inch count yielding a tighter plain weave fabric than the 2.9 Oz. listed above. Can be used for the manufacture of tail booms and lightweight fuselages.
5.6 Oz./Sq.Yd.
Consist of 3 K carbon strands woven in a 12 1/2 x 12 1/2 strands per inch count yielding a tight plain weave fabric. Generally used as a reinforcement of large scale aircraft fuselages and wing wheel well areas.
GRAPHITE/Kevlar® 5.4 Oz. / Sq. Yd.
The Graphite/Kevlar® hybrid offers the stiffness of graphite and the impact resistance of Kevlar® in one material. It can be used for boat hulls and aircraft fuselages.
GRAPHITE/S GLASS 6.0 Oz. / Sq. Yd.
Graphite/S Glass was originally developed for the surf board market. It is easier to cut than the Graphite/Kevlar® and less expensive. Otherwise, it is used for many of the same applications as the Graphite/Kevlar®.
80/20 GRAPHITE / S GLASS 4.7 Oz. / Sq. Yd.
A woven semi-unidirectional fabric that has 80% 3K carbon tow positioned lengthwise and 20% S Glass fibers woven across it. It is one of the most economical reinforcement materials avail- able. Can be used under a lightweight glass when vacuum bagging to produce a very stiff foam wing.
