Advanced Composite Industries (ACI) has engineered a composite material form described as a
COMPOSITE DISC that replaces STEEL and ALUMINUM discs in STATIC and DYNAMIC industrial
machine applications.
A 42 inch Diameter Basic
Composite Disc.
Composite Disc's are used in a wide range of industrial applications. To meet
these varied needs Composite Disc's are manufactured using several foams.
Reinforced Foam - Polyurethane (PU)
foam reinforced with glass-cloth.
Used in the manufacture of Webbed
Composite Disc's.
2 lb/ft^3 Unreinforced Foam -
Polyisocynurate (PU) foam. Used in
the manufacture of Basic, Ribbed and
Special Composite Disc's

Basic Composite Disc - BCD
Special Composite Disc - SCD
Ribbed Composite Disc - RCD
Webbed Composite Disc - WCD
Composite disc material's are produced from a Composite Sandwich structure.
The sandwich structure is a staple product in Aircraft composite construction.
Composite Disc materials for industrial products are designed using high
performance carbon fiber skins separated by a closed rigid cell foam.
Basic Composite Disc's for structures
that are subjected to low loads.
This Webbed Composite Disc provides
high shear stiffness.
Ribbed Composite Disc's provide
high flexural and shear stiffness
structures.
Special Composite Disc's are used
primerly for structures that require
machining..

The Composite Disc strength and stiffness is provided by a Carbon Fiber Radial Laminate.
The Carbon Fiber Radial Laminate is built from layers. The number of layers dictated by the
Composite Disc application and laminate balance. Shown in the table are Composite Disc's
with Radial Laminates with up to six layers. Depending on the application more layers can be
added to the laminate to increase stiiffness and strength.
Composite Disc Surface Skin
The Composite Disc Radial Laminate
is protected by a Carbon Fiber Hybrid
Surface Skin. Surface Skin material
and coating options are available.
