An Overview Into the New ISO TS for Graphene-Related 2D Materials
Caio Lo Sardo, VP of MITO Material Solutions has taken a leading role in the first graphene document in development led by the U.S. committee within the International Organization for Standardization (ISO) Technical Committee (TC) 229, Nanotechnologies. Right now, when looking at graphene materials, no standard exists to classify graphene-related 2D materials and ensure the material will have concise technical specifications. The new standard includes a framework that is tailored to be useful for users, academia and regulators. This project will establish consensus-based parameters for commercial graphene purchases to confirm the material data sheets meet the expected standards. During this overview, Caio will share insights into the compilation of framework that have been built around graphene, with industry peer review, the study of the characteristics and zero in on what matters going forward for people who use graphene.

Using Recycled Carbon Fiber Nonwovens to Accelerate AAM Development
Advanced air mobility (AAM) is reshaping the future of passenger and cargo transport, prioritizing lightweight and sustainable materials to drive advancements in electric flight and unmanned aerial vehicle (UAV) technology. In this webinar, Dr. Mandy Clement and Dr. Tim Swait will present a recent collaboration between the Advanced Manufacturing Research Centre (AMRC) and James Cropper. This pioneering project focused on developing reinforced UAV wing skins that offer strength, lightweight properties and recyclability in equal measure. In the project, the emphasis was on the use of advanced manufacturing techniques, such as tailored fiber placement (TFP), to precisely reinforce critical areas of the UAV wing skin without adding unnecessary weight. James Cropper’s recycled carbon nonwovens are utilized within the project to facilitate part manufacture via TFP, providing a lightweight substrate for continuous fibers to be stitched to, thereby improving handling during production. The webinar will focus on the project’s main objectives, discussing the challenges and material validation that resulted in the delivery of highly efficient, lightweight UAV structures with sustainable materials integral to the design and successful manufacture. Agenda: Introduction to the AMRC’s project to develop lightweight, reinforced wing skins for a UAV demonstrator The selection and testing of materials to support UAV part design and manufacture An overview of recycled carbon nonwovens covering their structure, supply, key differences from virgin fiber and the benefits they offer The main conclusions from the project, outputs and next steps

Assessing Surface Adhesion: Maintaining Quality in Composites Prep for Strong Bonds
Bond failures can have severe consequences for manufacturers, including increased scrap rates, damage to brand reputation, costly warranty claims and even safety hazards. These failures often stem from inadequate surface preparation, highlighting the critical importance of surface energy, the substrate's ability to interact effectively with adhesives, coatings or sealants at the molecular level. Brighton Science, with over two decades of experience in investigating bond failures, has found that over 90% of these issues originate from insufficient surface preparation. This webinar will provide a concise overview of surface energy and its crucial role in achieving successful adhesion. By attending this webinar, you will gain valuable insights into the fundamental principles of surface energy and its impact on adhesion. You will learn how to implement WCA measurements as a robust quality control metric and leverage Brighton Process Monitor to streamline surface energy analysis and enhance overall production efficiency. Agenda: Discover how to identify and address critical control points within your manufacturing process that significantly impact bond quality Learn how other companies have successfully utilized water contact angle (WCA) measurements to generate rapid, safe and reliable data for integrating surface energy as a crucial quality key performance indicator (KPI) Explore Brighton Process Monitor, a powerful application within the BConnect networked surface monitoring system
