  • Fibre Architecture: Availability, pros and cons, and selection for my application

    Selecting the form of fibre, often referred to as the fibre architecture is a critical decision during the development process. Fibre architecture has a significant effect on cost, processability, defect generation, design/geometry limitations, damage tolerance, and other outcomes of a composite part. Individual fibres are grouped into bundles of thousands of fibres called tows. These ... Read more

  • Special Webinar: Strengthening the Canadian Advanced Manufacturing Innovation Ecosystem: What types of intellectual property matter, and to whom?

    Online

    Innovation in advanced manufacturing is essential to maintaining and growing good quality jobs in Canada, as well as ensuring domestic supply of critical products. There is great pressure to move advanced manufacturing production offshore to lower labour cost jurisdictions, in order to improve margins. An alternative way to improve margins and profitability is through product ... Read more

  • Understanding polyester resin processing: the effect of ambient temperature on final part cure

    Controlling the curing parameters of resin, often referred to as thermal management, has a significant effect on the outcome of a thermoset polyester resin and therefore the overall performance of a composite part. Allowing polyester resin to cure under ambient conditions is the most common technique used in industry. One major drawback of this technique, ... Read more

  • Composites Process Simulation: A Review of the State of the Art for Product Development

    A fundamental concept in materials science is that process history leads to microstructure evolution, which in turn determines mechanical and functional properties. For composite components, where the material is transformed at the same time as the component is created, the local process history is a function of the whole processing system which includes material(s), part ...

  • The Composites Knowledge in Practice Center – une ressource ouverte pour les connaissances et les meilleures pratiques en matière de fabrication de composites

    Les composites sont des matériaux incroyables quand tout va bien - ils permettent des produits innovants et autrement impossibles. Mais la fabrication est difficile et une aide est souvent nécessaire pour développer, optimiser et dépanner les processus. Parfois, l'aide nécessaire est une orientation directe sur les meilleures pratiques spécifiques pour traiter un problème immédiat, et ... Read more

  • The Composites Knowledge in Practice Centre – an open resource for composites manufacturing knowledge and best practices

    Composites are incredible materials when things go right – they enable innovative and otherwise impossible products. But manufacturing is difficult, and help is often needed to develop, optimize and troubleshoot processes.  Sometimes the help needed is direct guidance on specific best practices to deal with an immediate issue, and sometimes there is time to expand ...

  • Deconstructing composites processing: Why it seems so complex and how to think about it in a structured way

    Composite materials come in many different forms, shapes, and sizes. While this allows for flexibility in tailoring the design, it also results in many different possibilities for manufacturing, which can seem complicated and daunting. However, despite there being numerous choices for manufacturers, the complexities often associated with composite material processing can be deconvoluted and approached ... Read more

  • Parameters for Structural Analysis of Composites

    Structural analysis of composites requires material properties such as elastic and strength values. Physical testing, handbook/database values, micromechanics, and classical lamination theory are all sources of these properties; but when are they valid and what are their advantages, disadvantages, hidden challenges and quirks? When you need nine unique values just to define the elastic response ... Read more

  • Costing Composite Parts

    Accurately estimating the cost of manufacturing a composite part is essential to the success of small, medium and large businesses alike; but where should you begin? Many factors such as material and consumable prices, labour cost, purchase and maintenance of equipment and tooling, energy cost, development cost, overhead cost as well as production run numbers ...
