Composite tensile specimen preparation is made easy with TensileMill CNC's
line of tensile preparation machines. The ASTM D3039 is a polymer composite
tensile test. It measures the required force to break a given polymer matrix
composite tensile sample, as well as how much specimen elongates or
stretches before reaching that breaking point. Tensile tests create what is
known as a stress-strain diagram. This diagram is used to discern tensile
modulus or Young's modulus, the stiffness of the material. The most common
use of this data specify a material for a given function, so parts can be
designed that will withstand a particular application force. It also serves
as a general quality control check for a given type or batch of materials.
The physical properties of many materials can vary depending on ambient
temperature. Therefore, depending on the intended application, the ASTM
D3039 test can be run at a wide variety of temperatures to ensure, to the
greatest possible degree, that the sample is tested under conditions similar
to what will be found in the expected end-use environment. Examples include
composite materials designed for use in airplanes, automobile engines,
aerospace functions (e.g. satellites), or anything involving a high level of
heat friction, such as oil drilling.
ASTM D3039 sample preparation most commonly involves a constant rectangular
cross section measuring one inch (25 mm) wide and ten inches (250 mm) long.
Specimen conditioning for the D3039 test should ensure a surface that will
be firmly gripped during testing. If desired, tabs can be bonded to the
specimen's ends to avoid gripping damage.
From tensile test results the following calculations can be made:
* Tensile strength (MPa or PSI)
* Tensile chord modulus of elasticity (MPA or PSI)
* Tensile strain (%)
* Poisson's ratio
* Transition Strain (%)
The ASTM D3039 test is appropriate for composite tensile and polymer tensile
coupons, composite tensile and polymer tensile dog bones, and fibre
composite tensile samples. If you require composite material testing,
