Laminated and sandwich composites can develop internal matrix cracking, delamination, fiber damage, disbonding, or, in sandwich construction, core damage while the exposed surface shows limited visible change. Appropriate nondestructive examination may include ultrasonic methods, thermography, radiography, shearography, or other techniques depending on the material, geometry, access, anticipated damage, and required sensitivity. Nondestructive examination can identify or characterize indications that warrant evaluation, while selected sections or representative samples may provide additional information when destructive examination is appropriate. Detection of an indication does not by itself establish its causal or acceptance significance.
Delamination is separation between plies or layers of a laminated composite. Depending on the material and service history, it may develop from impact, processing-related conditions, cyclic loading, excessive out-of-plane stresses, environmental exposure, or other damage mechanisms. Its size, depth, location, neighboring matrix or fiber damage, and relationship to the laminate architecture can help assess how the separation developed and whether it is technically significant to the reported performance.
Fiber-reinforced composites are often direction-dependent, so reinforcement orientation and stacking sequence can strongly influence stiffness, strength, damage progression, and load transfer in different directions. Changes in ply orientation, sequence, thickness, fiber content, or reinforcement placement may therefore alter component response depending on the applied loads and overall laminate architecture. Drawings, specifications, orientation records, manufacturing documentation, nondestructive examination where applicable, and physical sections can be compared to assess whether the documented construction corresponds with the intended layup.
Composite performance can depend on constituent materials, reinforcement placement, fiber volume, resin or matrix distribution, cure or consolidation conditions, porosity, contamination, ply alignment, wrinkles, and other processing variables. Some irregularities may affect strength, fatigue resistance, environmental durability, or damage tolerance, but their technical significance depends on their type, size, location, material system, loading, and applicable acceptance requirements. Manufacturing records, cure data, nondestructive examination, microscopy, sectioning, constituent or void-content testing, and other appropriate material tests can help determine whether processing-related conditions are present and relevant to the reported failure.

Testify in Court
Presents specialized findings and opinions clearly to judges, juries, arbitrators, or other decision-makers.
Fracture surfaces and exposed interfaces can provide evidence of whether separation occurred within an adhesive, at an adhesive-to-composite interface, within the composite substrate, or between laminate plies. The examination may also identify matrix cracking, fiber fracture, interlaminar delamination, cohesive adhesive failure, interfacial separation, or mixed failure modes. Surface preparation, adhesive coverage, cure conditions, bond geometry, composite condition, loading, and environmental exposure should be evaluated together because a bonded-joint failure reflects the performance of the adhesive and adherends as a system. When adhesive chemistry or bond performance becomes the principal dispute, separate Adhesives expertise may also be appropriate.
