This webinar describes filament winding processes and technologies to produce fiber-reinforced polymer composites. Historically, filament winding is known as a composite fabrication process by which resin-wet fibers are deposited on a rotating mandrel following specific geometric paths creating structures of revolution. The webinar first explores the basics of the filament winding process, with focus on ... Read more

The majority of parts composed of composite materials are joined with other parts before becoming the final product. In addition to adhesive bonding, bolted joints are a common method of joining composites. They can be strong, and reliable, while allowing for disassembly if required. This AIM Event webinar will provide an introduction to bolted joints ... Read more

Sandwich structures (aka sandwich panels) find themselves in a wide variety of applications. Their notable qualities include high specific strength, stiffness, and energy absorption. Like any structure, sandwich panels may require repair when damaged. This webinar will cover various types of damage and the damage assessment process. It will explore how decisions to repair, replace, ... Read more

Non-Destructive Testing (NDT) is commonly used to assess the quality and current condition of composite materials. It is used to provide insight into the presence of defects and/or the extent of damage without destroying the part, thereby allowing it to go back into service if appropriate. Many parts go through NDT before being put into ... Read more

Many composite structures encounter damage, which needs to be identified and assessed, and a decision to repair made. Repair may be advantageous in terms of cost and/or faster return to service. It may also be a more sustainable option versus replacement. This webinar is an introduction to repair of composite structures. It will start with ... Read more

Polymer matrix composites exhibit viscoelastic behaviour that may affect the long-term performance of the composite structure. Viscoelastic materials display energy dissipation and a memory effect meaning that past mechanical and thermal loads will alter the material. The determination of the material properties and the prediction of their long-term response requires a range of experimental, computational, ... Read more

The majority of parts composed of composite materials are joined with other parts before becoming the final product. Adhesive bonding is a common method of joining composites as it can be strong, quick, cost effective, and reliable, with minimal weight addition. An introduction to bonding composite materials will be presented in this two-part webinar series. ... Read more

Sandwich structures (sandwich panels) are excellent for applications that benefit from high strength to weight ratios. They find themselves in a variety of applications in aerospace, marine, automotive, wind energy, and other industries. A previous webinar, Introduction to Sandwich Structures – Materials and Processing (https://compositeskn.org/KPC/A322) provided an introduction and overview of sandwich structures. This upcoming ...

A composite part requires some form of tooling to take shape during the curing or crystallization process. The tooling will also assist in the deposition and alignment of fibre as well as provide the surface finish of the part. Tooling must be able to stand up to the processing requirements such as temperature and pressure ... Read more

It was thought that the use of composite materials would lead to a net positive environmental impact through their use in aircraft, wind turbines, and hydrogen pressure vessels, among other applications. The reality is that most manufacturing practices used to produce these composite parts are highly inefficient, producing copious amounts of waste for which we ... Read more

Composite materials inherently contain defects, which introduce variability and often restrict their mechanical properties. Among these defects, porosity is one of the most prevalent and can negatively affect both the structural integrity and aesthetics of the material. The presence and extent of porosity are largely determined by processing parameters. Previously, we presented a comprehensive list ... Read more
