Committee D30 on Composite Materials
Committee D30 formed in 1964 (with heritage to
the early ‘50s) out of Committee D20 on Plastics
Current (2009) D30 Scope
“The Committee will develop standard test methods, practices,
terminology, and guides; sponsor symposia; stimulate research;
and exchange technical information pertaining to composite
materials (primarily those with fibrous reinforcement), as well as
to reinforcing fibers with a Young's modulus greater than 20
GPa (3 Msi).
This Committee will not develop standard specifications.”
D30 Objective
A complete, effective, and coordinated suite
of testing standards for composites

ASTM International Balloting Process
COMMITTEE ON
STANDARDS (COS)
MAIN COMMITTEE
SUBCOMMITTEE
TASK
GROUP
4) As a final check, a standing committee
(COS) of the ASTM Board of Directors
reviews the process by which each standard
is developed or revised, to ensure compliance
with ASTM regulations.
3) After S/C approval the Main Committee votes. If
approved it is presented to the Committee on
Standards for final review. Otherwise it returns to
the Task Group for re-work & balloting is repeated.
2) A completed draft is voted on by the
Subcommittee. If approved, it moves to a
Main Committee vote. If not, it returns to the
Task Group for re-drafting.
1) Starting Point. Documents are drafted,
and continually revised, in the Task Group
by a few members who specialize in the
subject matter. This is where the bulk of
the activity occurs.

C393: core shear stiffness and strength by long beam flexure (test method)
– 3-point loading configuration is standard; alternative configurations retained for
historical continuity.
– Includes guidelines for specimen design to promote core shear failure.
D7249: facing stiffness and strength by long beam flexure (test method)
– 4-point loading configuration is standard.

Recent Efforts:
Civil Infrastructure Standards

D30.05 subcommittee working with ACI Committee 440 to publish civil
infrastructure composite test methods.
– TG consists of about 20 D30 and ACI subject matter experts.
– Key contacts are Drs. Abdul Zureick and Russell Gentry (Georgia Tech).
– D30 met jointly with ACI in March 2009 (San Antonio, TX).


17 ACI 440 documents being transitioned into ASTM documents.
Four ACI standards are currently published as ASTM standards:
– D 7205/D7205M: Tensile Properties of Continuously-Reinforced Polymer Matrix
Composite Bars
– D 7290: Practice for Evaluating Material Property Characteristic Values for
Polymeric Composites for Civil Engineering Structural Applications
– D 7337/D7337M: Tensile Creep Rupture of Fiber Reinforced Polymer Matrix
Composite Bars
– D 7522/D 7522M: Pull-Off Strength for FRP Bonded to Concrete Substrate

Another ACI standard is in D30 committee ballot:
– WK17184: Tensile Properties of Fiber-Reinforced Polymer Matrix Composites
used for Strengthening of Civil Structures
16
Recent Efforts:
New DMA Tg Standard

D 7028 for glass transition temperature by Dynamic Mechanical
Analysis (DMA) was published in 2007.
– Based upon process improvements derived from a round-robin study.
– Significant efforts by Mike Stuart (Cytec) and Joy Wu (Hexcel).

Key process improvements:
– Guidance on equipment calibration.
– Methods for characterizing and interpreting DMA thermograms.

A research report from the round-robin testing is in preparation.
17
Current Standards Initiatives

Future D30 Objectives
• Add more quantitative precision statements based on
accurate and effective round-robin test programs
• Improve balance between a concise lab procedure and
detailed explanatory guidance or requirements
• Increase exposure and acceptance in non-aerospace and
international markets
• Expand into non-aerospace statistical assurance of
measured properties
22
Current and Future Relationships

Cooperation with CMH-17 (MIL-HDBK-17) on consensus
test methods and testing guidance

Cooperation with SAE Committee P-17 on test methods for
consensus standard composite material specifications

Cooperation with ACI Committee 440 on civil infrastructure
standards

Standards supporting marine product development

Collaboration and joint meetings/conferences with
CMH-17, ASC,and SAMPE

