In addition to the robust Conference Programming sessions during CAMX during CAMX, attendees can take an in-depth look at specific topics with Tutorials. These three hour courses, held in the afternoon of Monday, October 15th, and Tuesday, October 16th, immerse attendees of all technical backgrounds in a single area of focus. Tutorials are included with a Premium registration, and are available for purchase separately with all other registration types.

This tutorial on thermoplastic composites focusses on thermoplastic materials, processes and applications for the aerospace market. After an introduction on trends and the need for low weight structures, an overview of thermoplastic polymer types and different forms of thermoplastic composites is given. The reasoning behind thermoplastics is then explained, followed by a number of processing techniques. In the second part of the tutorial, successful aerospace applications are presented, followed by current developments and an outlook towards the future. The tutorial concludes with a note on thermoplastics in automotive.

This tutorial provides an overview of enabling technologies related to joining composite structures with both fastened and adhesive bonded joints. Topics include a discussion on fasteners, types and methods used in composite assembly, holes and countersinks, bonding vs fastening, surface preparation methods, abrasion methods, risks and benefits of grit blasting, prepreg vs dry peel ply, plasma treatments, methods of validation of surface cleanliness and wetting readiness. Other topics include; proper adhesive selection, controlling bondline thickness, microbeads vs carrier materials, bonding to core materials, providing uniform clamping pressure along the joint, and assuring proper cure of the adhesive. This session also incorporates an overview of the effect of fiber forms and orientation at interfacial surfaces and a comparison of failure modes in bonded structures. This is an interactive learning event and all attendees are encouraged to participate.

The advanced materials, manufacturing processes, and design tools available to today’s design engineer provide options that can be overwhelming. Identifying and then navigating through this maze of possibilities requires a broad perspective. In an attempt to “teach by example”, this session will discuss prior design projects presenting specific design challenges and the methods used to address them. Techniques for design optimization will also be discussed.
Wes Hobbs, Davis Technology College, Lead Composites Instructor
This tutorial will consist of topics that will briefly cover most knowledge required to fabricate Composite parts of an advanced nature. From preparation of molds, safety issues, vacuum bagging, prepreg, core materials, repair, to preparation for autoclave cure. We will also touch on different alternative processing methods used in the advanced composites industries.

As Industrial IoT and Artificial Intelligence (AI) technologies are becoming increasingly central to the world of advanced manufacturing, there is a growing interest in their potential impact on aerospace & composites manufacturing. Terms such as ‘Internet of Things’ or ‘Industry 4.0’, ‘Context Aware Software’, ‘Edge and Cloud Computing’, ‘Machine Learning’, ‘Digital Twin’, ‘Digital Thread’ and others have bubbled up into daily discussions, often with limited clarity as to what they mean, and – more importantly – as to how they all come together in practice, to create business value. This tutorial will first introduce and discuss key elements of these technologies, and then dig deeper into various techniques of leveraging them in composites production. The talk will involve real-life examples, including implementation challenges and resulting benefits. We will conclude with further discussion of new opportunities created by these exciting technologies, as they are surfacing almost daily.

Designing a structural composite is only the first step in actually manufacturing and processing to then obtain the part engineering designs. This tutorial will cover the composite material systems and the process selection in order to then “optimize” the part one desires to build in Production. Attendees will receive an overview of composite material characterization as it relates to various processing options. Attendees will be exposed to the importance of certain testing/analysis as related to the product cycle of concept and quality control during Production. What is the importance of getting the manufactured part to match the model? Why are proper material selection, manufacturing process selection, and, implementation of Manufacturing Plans all important? These will be covered as well as discussing several processes such as “automated fiber placement”, “resin selection” for end-use environmental conditions, “processing options” and other important aspects — such that there are no “surprises” when the final structural composite part is removed from the tooling, mold, die or forming entity.

Epoxies are an important and widely used thermoset. . They are used for everything from jewelry adhesives to advanced composite structures for aerospace and space applications. The epoxies have characteristics that provide properties suitable for a variety of purposes; can be are explained by the chemistry of the epoxide functional group as well as the curing reaction with hardeners. The commercial success of epoxy chemistry spans over 60 years of dynamic changes. Its high utility is due to the flexibility and ease of use of the integral epoxy chemistry. This overview of epoxies will presented the chemistry, manufacturing, application, and market of the epoxy class of thermosetting materials.
