ASTM D5467 / D5467M - 97(2010
Standard Test Method for Compressive Properties of Unidirectional Polymer Matrix
Composites Using a Sandwich Beam
1.1 This test method covers the in-plane compressive properties of polymer matrix
composite materials reinforced by high-modulus fibers in a sandwich beam configuration.
The composite material forms are limited to continuous-fiber composites of unidirectional
orientation. This test procedure introduces compressive load into a thin skin bonded
to a thick honeycomb core with the compressive load transmitted into the sample by
subjecting the beam to four-point bending.
1.2 This procedure is applicable primarily to laminates made from prepreg or similar
product forms. Other product forms may require deviations from the test method.
1.3 The values stated in either SI units or inch-pound units are to be regarded separately
as standard. The values stated in each system may not be exact equivalents; therefore,
each system shall be used independently of the other. Combining values from the two
systems may result in non-conformance with the standard.

Four Point Flexure Fixture
Specimen support spans from 1/2” to 22". Adjustable four point loading head with
loading spans from 1/2” to 6". Loading roller points will accommodate specimens
up to 4.0” wide. The fixture is constructed from high strength steel with a protective
black oxide finish in accordance with ASTM C393 and D5467.
Support Base - 24" long by 4" wide with a T-slot running the length of the base.
The upper and lower surfaces are ground flat and parallel. The support block separation
is measured along a center finding scale located on the the front surface of the
support base. The base is used on a platen (not included) or with the 1” -14 mounting
threads.
Specimen Supports - 4" wide by 4" tall with alignment rails which fit in the T-slotted
support base. The supports are supplied with 0.750"ø support pins and pads, which
are held in alignment grooves with O-rings. The center position of the loading pin
is indicated by a scribe line which runs down the side of the support to the center
finding scale. The supports are free to slide anywhere along the support base and
may be reversed for short and long spans.
8” Four Point Loading Head - 4" wide by 8” long with two adjustable loading pin
supports. The 8" long loading rail allows the loading anvils to be adjusted to any
loading span from 1/2" to 6". The anvils are channeled to insure proper alignment
to the loading rail. The anvils are supplied with 0.750"ø loading pins and pads,
which are held in alignment grooves with O-rings. The center position of the loading
pins are scribed in the anvils, which run along a center finding scale on the loading
rail. Supplied with 1”-14 loading coupling.
