A tensile test fixture for quick testing of materials with low transverse strength and relatively high longitudinal strength. After the tensile test fixture is loaded into a universal testing machine, such as a two-part load frame, a first test specimen is aligned and tensile tested. Alignment of the first test specimen ensures that all consecutive test specimens are aligned within the tensile test fixture without further alignment required.

A test fixture configured to attach to and apply a tensile force to a test specimen. The test fixture may include a first clevis section and a second clevis section that are each configured to be attached to the test specimen. Each of the first and second clevis sections may include a fixed block and a movable block. Connectors connect the clevis sections together and hold the test specimen. The first and second clevis sections may be moved apart to apply a force to the attached test specimen to test one or more properties of the test specimen.

Provided is a material testing machine capable of giving an appropriate testing force to a testing piece. The material testing machine performs a three-point bending test on a testing piece and includes a support mechanism that supports the testing piece, an indenter that is connected to an ultrasonic oscillator and gives ultrasonic vibration to the testing piece by abutting against the testing piece, and a load mechanism that presses the indenter to the testing piece supported by the support mechanism. The support mechanism includes: a spherical seat that has a lower member equipped with a spherical-surface-shaped concave portion or convex portion, and an upper member equipped with a spherical-surface-shaped concave portion or convex portion having a shape corresponding to the concave portion or convex portion in the lower member; a holding portion; and a first movable member.

The invention pertains to performing bonding strength testing between a test material and a container. A sample preparation device to make a test sample was disclosed. This device included a container with an insert on each end. The inserts have a portion that protrudes into the container. When test material is added to the sample preparation device, a groove was formed in test sample. These grooves reduce the amount of boundary effects that are present during testing. A system and method for performing bond strength testing was also disclosed. In this system, a test sample was formed using the sample preparation device. This is placed upon a support and a half-spherical force applier is placed on top of the test sample. A press is used to apply force to the force applier and indirectly to the test sample.

A system for testing adhesive is disclosed, comprising a pull testing machine and a rigid spine. The rigid spine has a face extending along a longitudinal axis between a first and second projection, and one of the projections is moveable relative to the other. The face is configured to support a substrate, with a flexible media adhered to the substrate. The rigid spine also has a coupler configured to connect the spine to the pull testing machine.

The present disclosure provides an adhesion strength test jig includes a plurality of adjusting rods which are connected in an end-to-end manner so as to define an accommodating space for accommodating an adhered element. Each of the adjusting rods includes a rod body and a sliding block located at one end of the rod body, and the sliding block of each of the adjusting rods is capable of sliding along the rod body of another adjusting rod connected thereto, so as to adjust a size of the accommodating space.

A compression test fixture including a first specimen engagement member having a first channel, the first channel having a first depth; a second specimen engagement member having a second channel having a second depth that is different than the first depth; and at least one coupling member engaged to both the first specimen engagement member and the second specimen engagement member such that a gap is defined between the first specimen engagement member and the second specimen engagement member, where the first channel and the second channel support the test specimen within the gap such that at least one opposing major surface of the test specimen is visible within the gap.

A tensile specimen, in particular a fiber-composite-material tensile specimen, includes a test portion which comprises a fiber material and a tensile stress direction which is predetermined for a material test, and a force-introduction portion, wherein the fiber material in the force-introduction portion extends at least in part along a face which is oriented obliquely to the tensile stress direction.
