The world of materials testing is changing
- materials are getting stronger, stiffer, and lighter
- test standards are becoming stricter
- testing labs are asked to perform more complex analytical tests

Manufacturing processes are moving away from using traditional bolts and rivets to using new, stronger adhesives to hold together materials such as composites and aluminum. With this increase in bonded manufacturing, it is more important than ever to accurately test the adhesive strength of bonds to prevent catastrophic failures.

As composites continue to be adopted in more industries, fiber-reinforced plastics can be found in products that people interact with every day, including cars and sporting goods. Fiber-reinforced plastics consist of reinforcing fibers surrounded by a plastic matrix. There are several types of fibers that can be used including glass, carbon fiber, and aramid which give the material its high tensile strength. The matrix gives the composite the compressive strength and, in the case of fiber reinforced plastics, can be made using thermoset or thermoplastic polymers.

Digital Image Correlation (DIC) is an analytical technique that compares images of a specimen’s surface during testing to generate full-field strain maps. This technology gives you more information than a traditional point-to-point extensometer or a strain gauge and allows you to see the complete story of the material’s behavior beyond the stress strain curve.

By 2016, the US car industry will need to average 34.5 mpg and by 2025, cars will need to average 54.5 mpg. In order to meet these new requirements, manufacturers will have to implement a number of changes including new engines, technologies, and materials. Lightweight materials are one of the most important avenues to pursue because for every 10% reduction in weight, fuel efficiency is increased by 6–7%.

When testing stiff or brittle materials, such as composites, alignment is crucial—even instances of slight misalignment can throw off test results.
