Sam Gnaniah

Sam Gnaniah has more than 23 years' experience covering broad areas in thermal analysis and has been employed in NPL's Materials Division for the past 14 years.

Sam is well-connected with the thermal analysis community in the UK having in the past been a committee member for the Royal Society of Chemistry Thermal Methods Group and member of the ASTM Committee E37 for thermal measurements.

He is also co-author of a good practice guide for thermal analysis measurements for composites and adhesives (NPL GPG 62), which was the result of a collaborative project with UK industry, academia, accreditation body and four major instrument suppliers.

Sam is a member of the Institute of Materials, Minerals and Mining.

Current Interests

He currently leads an international intercomparison exercise on assessing the cure state of composites as part of VAMAS TWA 5 which will feed into a major new thermal analysis ISO standard on Dynamic Mechanical Analysis (ISO 6721-11) drafted by NPL. This new standard will significantly affect the method of testing using the commercially available instruments.

A reference specimen consisting of a carbon-fibre/epoxy laminate with a temperature reference material, indium, fully embedded in it has been developed at NPL for assessing the effect of thermal lag on the measured glass transition temperature.
