PERFORMANCE SPECIFICATION
PREPREG, UNIDIRECTIONAL TAPE, CARBON (GRAPHITE) FIBER HIGH TEMPERATURE RESIN
IMPREGNATED, 316°C (600°F)
This specification is approved for use by all Departments and Agencies of the
Department of Defense.
1.
SCOPE
1.1
Scope.
This specification establishes the requirements for carbon
fiber/high temperature resin prepreg in the form of unidirectional tape suitable
for the fabrication of structural laminates intended for use at temperatures up
to and including 316°C (600°F) (see 6.1).
1.2
Classification of material.
1.2.1
High temperature resin.
An organic resin either thermoset or
thermoplastic which can withstand temperatures up to and including 316°C (600°F)
while still retaining required mechanical, chemical and physical properties.
1.2.2 Prepreg. The carbon (graphite) fiber high temperature resin impregnated
unidirectional tape conforming to this specification is termed a "prepreg"
material (preimpregnated).
The unidirectional prepreg tape described in this
specification is a composite material in which the polyimide resin is partially
cured and the carbon fiber reinforcement is oriented in one direction
(unidirectional).
