At a glance
Scanning electron microscopy can support an explanation of a composite fracture, but an image should not be asked to prove more than it shows. Preparation and image selection influence interpretation.
Key points
- Features interpreted as fibre pull-out, interfacial separation or matrix deformation should be considered alongside how the specimen was broken and prepared.
- Retain representative images with scale bars and specimen identity.
- Describe an interpretation as an interpretation where mechanisms remain uncertain.
Technical context #
Features interpreted as fibre pull-out, interfacial separation or matrix deformation should be considered alongside how the specimen was broken and prepared. A few selected fields may not represent the whole fracture surface.
What to measure and document #
Retain representative images with scale bars and specimen identity. Compare controlled samples and include observations that do not support the preferred explanation. Link microscopy to mechanical measurements rather than using visual impressions as a substitute for them.
Implications for development and specification #
Describe an interpretation as an interpretation where mechanisms remain uncertain. A smooth-looking interface does not by itself establish durability or a stronger commercial product. Research images are evidence for a specific specimen, not a generic quality certificate.
