An investigation into the inspection capabilities of in-field advanced ultrasound detection for use on ultra-thick (20 to 100 mm) glass fibre-reinforced polyester composites is presented. Plates were manufactured using custom moulding techniques, such that delamination flaws were created at calibrated depths. The full matrix capture technique with an on-board total focussing method was used to detect flaws scanned by a 0.

- The study investigates how two types of single polymer films (thermoplastic polyurethane and adhesive epoxy) affect the mechanical properties of composite laminates.
- The laminates were made using either a co-curing or a secondary bonding process, and their interlaminar fracture toughness was measured in two modes.
- The results showed that the PU film significantly enhanced both modes of toughness (290% for mode I and 50% for mode II), while the epoxy film also improved toughness, with increases of 175% for co-curing and 75% for secondary bonding in mode II.
Objectives: Previous studies have established that essential information is inconsistently provided during the transfer of extended care facility (ECF) patients to the emergency department (ED). The authors tested the hypothesis that a one-page, standard ECF-to-ED transfer form would change the rate of successful documentation of ECF patient information.
Methods: The design was a pre- and postintervention investigation.
