Inspecting GFRP composites

22nd April 2022

SubTera has recently completed a successful Innovate UK funded feasibility study in collaboration with the UK’s National Composites Centre (NCC).

The study’s aim was to characterise SubTera’s technology for the purpose of non-destructively testing (NDT) glass-fibre reinforced plastic (GFRP) components.

GFRP is increasingly being used as a protective cladding material on energy and processing pipework, and is used extensively in the manufacture of wind turbine blades.

Working closely with the NCC’s NDT team, led by Rob Rose, SubTera’s sub-terahertz sensor technology detected a variety of defects, including impact damage, delaminations, and inclusions.

Speaking about the work, Rob Rose said “it’s always exciting to work with UK technology SMEs, to help them prove concepts that broaden the potential applications of their technologies in different materials and industrial sectors. We look forward to hearing how our work with SubTera has impacted their penetration of these new markets in the months to come.”

Prior to this feasibility study, SubTera had completed earlier research to understand and measure, transmission of sub-terahertz energy through GFRP materials.
