Designation: D7137/D7137M −23
Standard Test Method for
Compressive Residual Strength Properties of Damaged
Polymer Matrix Composite Plates
1
This standard is issued under the ﬁxed designation D7137/D7137M; the number immediately following the designation indicates the
year of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last
reapproval. A superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
1. Scope
1.1 This test method covers compression residual strength
properties of multidirectional polymer matrix composite lami-
nated plates, which have been subjected to quasi-static inden-
tation per Test Method D6264/D6264M or drop-weight impact
per Test Method D7136/D7136M prior to application of
compressive force. The composite material forms are limited to
continuous-ﬁber reinforced polymer matrix composites with
multidirectional ﬁber orientations, and which are both symmet-
ric and balanced with respect to the test direction. The range of
acceptable test laminates and thicknesses is deﬁned in 8.2.
NOTE 1—When used to determine the residual strength of drop-weight
impacted plates, this test method is commonly referred to as the
Compression After Impact, or CAI, method.
1.2 The method utilizes a ﬂat, rectangular composite plate,
previously subjected to a damaging event, which is tested
under compressive loading using a stabilization ﬁxture.
NOTE 2—The damage tolerance properties obtained are particular to the
type, geometry and location of damage inﬂicted upon the plate.
1.3 The properties generated by this test method are highly
dependent upon several factors, which include specimen
geometry, layup, damage type, damage size, damage location,
and boundary conditions. Thus, results are generally not
scalable to other conﬁgurations, and are particular to the
combination of geometric and physical conditions tested.
1.4 This test method can be used to test undamaged polymer
matrix composite plates, but historically such tests have
demonstrated a relatively high incidence of undesirable failure
modes (such as end crushing). Test Method D6641/D6641M is
recommended for obtaining compressive properties of undam-
aged polymer matrix composites.
1.5 Units—The values stated in either SI units or inch-
pound units are to be regarded separately as standard. The
values stated in each system are not necessarily exact equiva-
lents; therefore, to ensure conformance with the standard, each
system shall be used independently of the other, and values
from the two systems shall not be combined.
1.5.1 Within the text the inch-pound units are shown in
brackets.
1.6 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 appro-
priate safety, health, and environmental practices and deter-
mine the applicability of regulatory limitations prior to use.
1.7 This international standard was developed in accor-
dance with internationally recognized principles on standard-
ization established in the Decision on Principles for the
Development of International Standards, Guides and Recom-
mendations issued by the World Trade Organization Technical
Barriers to Trade (TBT) Committee.

3. Terminology
3.1 Deﬁnitions—Terminology D3878 deﬁnes terms relating
to composite materials. Terminology D883 deﬁnes terms
relating to plastics. Terminology E6 deﬁnes terms relating to
mechanical testing. Terminology E456 and Practice E177
deﬁne terms relating to statistics. In the event of a conﬂict
between terms, Terminology D3878 shall have precedence
over the other standards.
3.2 Deﬁnitions of Terms Speciﬁc to This Standard:
3.2.1 If the term represents a physical quantity, its analytical
dimensions are stated immediately following the term (or letter
symbol) in fundamental dimension form, using the following
ASTM standard symbology for fundamental dimensions,
shown within square brackets: [M] for mass, [L] for length, [T]
for time, [θ] for thermodynamic temperature, and [nd] for
non-dimensional quantities. Use of these symbols is restricted
to analytical dimensions when used with square brackets, as
the symbols may have other deﬁnitions when used without the
brackets.
3.2.2 nominal value, n—a value, existing in name only,
assigned to a measurable property for the purpose of conve-
nient designation. Tolerances may be applied to a nominal
value to deﬁne an acceptable range for the property.
3.3 Symbols:
3.3.1 A—cross-sectional area of a specimen
3.3.2 CV—coefficient of variation statistic of a sample
population for a given property (in percent)
3.3.3 D—damage diameter
3.3.4 E

tion

3.3.6 h—specimen thickness
3.3.7 l—specimen length
3.3.8 n—number of specimens per sample population
3.3.9 N—number of plies in laminate under test
3.3.10 P
max
—maximum force carried by test specimen prior
to failure
3.3.11 S
n-1
—standard deviation statistic of a sample popu-
lation for a given property
3.3.12 w—specimen width
3.3.13 x

3.3.14 x¯—mean or average (estimate of mean) of a sample
population for a given property
4. Summary of Test Method
4.1 A uniaxial compression test is performed using a
balanced, symmetric laminated plate, which has been damaged
and inspected prior to the application of compressive force.
The damage state is imparted through out-of-plane loading
caused by quasi-static indentation or drop-weight impact.

摘要：

《ASTM D7137-D7137M-23 损坏的聚合物基复合材料板的压缩残余强度特性的标准试验方法》是一项用于评估纤维增强聚合物基复合材料在承受冲击损伤后剩余压缩强度的权威测试标准。该标准详细规定了在对复合材料层压板施加预定义的冲击（通常依据ASTM D7136进行）后，如何通过压缩加载测试来获取材料的压缩失效载荷与强度数据，从而量化材料对冲击损伤的容限能力。试验采用带有抗失稳夹具的专用压缩夹具，以防止试样在加载过程中发生整体屈曲，确保破坏发生在冲击损伤区域内部。本标准适用于碳纤维、玻璃纤维等
