ASTM D 5528 Document Information:
Title
Standard Test Method for Mode I Interlaminar Fracture Toughness of Unidirectional Fiber-Reinforced Polymer Matrix Composites
ASTM International
Publication Date:
Nov 10, 2001
Scope:
This test method describes the determination of the opening Mode
I interlaminar fracture toughness, GIc, of
continuous fiber-reinforced composite materials using the double
cantilever beam (DCB) specimen (Fig. 1).
This test method is limited to use with composites consisting of
unidirectional carbon fiber and glass fiber tape laminates with
brittle and tough single-phase polymer matrices. This limited scope
reflects the experience gained in round-robin testing. This test
method may prove useful for other types and classes of composite
materials; however, certain interferences have been noted (see
6.5).
The values stated in SI units are to be regarded as the
standard. The values given in parentheses are for information
only.
This standard may involve hazardous materials, operations, and
equipment.
This standard does not purport to address all of the safety
concerns, if any, associated with its use. It is the responsibility
of the user of this standard to establish appropriate safety and
health practices and determine the applicability of regulatory
limitations prior to use.
