PPE (Saint-Avold, France) offered live demonstrations to JEC Europe 2015 attendees of its EASYPERM technology, introduced at JEC Asia late in 2014. The system measures and then evaluates the ability of a fibrous reinforcement to allow resin flow, and characterizes that ability in three dimensions. PPE says EASYPERM is the only system currently on the market that offers an industrial- grade solution for measuring the permeability of a dry reinforcement by a liquid resin in both the through-thickness (z) and in-plane (x, y) dimensions. EASYPERM is said to be a reliable quality-control system because it relies on pressure measurement recorded automatically via a network of sensors (it is not affected by variables that might be introduced via human input). The sensor data is then post-processed using Darcy’s law. EASYPERM’s configuration also allows a visual check of the flow front. The system received the 2015 JEC Innovation Award in the “Laboratory Equipment” category.
