Mechanical Properties

A 40% weight reduction with six-fold increase
 in stiffness is possible when compared to
 conventional epoxy-glass composites.

Typical for a 10 ounce graphite cloth composite:

Tensile modulus............9.5x10E6psi
Flexural modulus...........9.4x10E6psi
Compressive Modulus........9.1x10E6psi
Tensile strength..........85.0x10E3psi
Flexural strength........110.0x10E3psi
Density..................0.055 lb/in^3

* Mounting bolt interface consists of four stainless steel inserts.

** Special surface tolerances up to 1/2 the standard are available on order.
