REDUCING VARIABILITY

In the world of composites testing, alignment is everything. Because of their anisotropic and brittle nature, composite materials are highly sensitive to even the slightest misalignment — leading to premature failures, inconsistent data, and costly misinterpretations. This white paper explores how proper alignment practices, robust test system design, and the right equipment can dramatically improve data accuracy, consistency, and regulatory compliance for safety-critical industries such as aerospace and automotive.

By reading this white paper, you will learn:

• How misalignment impacts test results — including effects on tensile strength and modulus
• The difference between angular and concentric misalignment — and how each introduces stress concentrations and premature failures
• Quantified benefits of good alignment — see how a well-aligned test compares to a poorly aligned test
• Key components for achieving precise alignment — from testing machines and load cells to grips and fixtures
