Fiberglass Reinforcement Sizing 101
James Chantler, September 2013
An introduction and general overview of the manufacture of fiberglass reinforcements is presented. Included is a general discussion of the role and components of the chemical coating on the glass fibers known as the sizing and why these chemicals are important to the manufacture and final properties of composites. This presentation explains what sizing is how it affects composite properties how it is applied to glass what classes of sizing chemicals are used and what each component does and why it is needed. The goal is to help the fiberglass industry educate customers and debunk the myth that all fiberglass is the same.
Ultrasonic Characterization of Fiber Reinforced Composites
Sarah Stair, September 2013
Several industries such as automotive aerospace and sports are incorporating fiber-reinforced composites into their products due to the high strength to weight ratio of these materials. Unfortunately the final part’s characteristics depend greatly on the manufacturing process and a non- destructive testing procedure is required to inspect the final part. This study utilizes ultrasonic A-scan and C-scan techniques to ascertain the material properties of a carbon fiber-reinforced composite based on the orientation of each lamina.
A Short History of Automotive Composites
Lindsay Brooke, September 2013
For 100 years plastics and composites have been vital to making vehicles lighter more durable and more efficient. But how well do you know their greatest milestones — and flops? Join veteran autowriter and SAE Magazines Senior Editor Lindsay Brooke as he turns on the way-back machine for a fun and surprising historical journey.
Design & Development of Precision Plastic Gear Transmissions
David Sheridan, September 2013
This presentation will provide a methodical and rational procedure for designing and developing high-precision injection-molded plastic gear transmissions that function satisfactorily across the entire range of manufacturing tolerances and operating conditions.
Direct Compounding—Insight and Results of the First Full-Scale Pilot Plant
Tobias Potyra, September 2013
The innovative Direct SMC process has reached a point where it can be introduced into industrial applications. This presentation gives an overview of the state of development of the process and will give an insight in the processing technology. Furthermore the full industrial scale process line will be shown as it is installed at the facilities of Fraunhofer ICT Germany.
Ke Feng, September 2013
With the aid of a unique lab scale test a new polyphenylene sulfide material has been developed to enable the first-ever 3D robotic blow molding production. Data on melt viscosity development and details in the test method will be discussed.
Improvement in the Simulation of Injection Molded Short Glass Thermoplastic Composites
Syed Mazahir, September 2013
This paper presents simulation results for prediction of fiber orientation in a center-gated disk using Folgar Tucker model with Newtonian flow and experimentally measured orientation at the gate as an initial condition. A steady moving front with circular shape was included to capture the effects of the frontal flow on fiber orientation. Quadratic and invariant-based optimal fitting closures are also assessed in shear and planar extensional flows and compared with experimental evolution of fiber orientation.
Thermoplastic Composite Structural Strut

PowerPoint Presentation at Automotive Composites Conference and Exhibition
Simulating Orientation of Long Semi-Flexible Glass Fibers in Three-Dimensional Injection Molded Thermoplastic Composites
Mark Cieslinski, September 2013
In this presentation a comparison between rigid and semi- flexible fiber-orientation models are assessed for long semi- flexible glass fibers in an end-gated plaque. Simulations were done under non-isothermal conditions taking into account entry effects and the fountain-flow behavior at the advancing front. Orientation predictions are compared to experimental data measured in the gate and mold cavity both along and away from the centerline.
Repairs for Advanced Composite Structures
Lou Dorworth, September 2013
This presentation provides a short overview of current repair methodologies used to restore structural integrity in advanced composites in aerospace and how these practices might be transferred to the automotive industry.
Progress with Polyurethane Matrix Resin Technology: High-Speed Resin Transfer Molding Processes and Application Examples
Stefan Kreilingr, Frank Fetscher, September 2013
Novel polyurethane matrix resin enables manufacturing of automotive composite parts via high-speed resin transfer molding (RTM) processes. Due to its inherent fracture toughness the polyurethane technology can offer superior fatigue resistance. Technical insights into the mass production of an automotive composite leaf spring will be given. In addition painting and assembly of composites via adhesive bonding are important steps along the process chain where further efficiencies can be realized.
The Influence of Bond Dam Design and Hard Hits on Bond-Line Read-Through Severity
Kedzie Fernholz, September 2013
An experiment to investigate the root causes of adhesive-induced distortion in Class “A” panels was completed. This experiment showed that features in the inner panel that change the thickness of the adhesive across the bead width are responsible for the visible distortions in the outer panel surface. In addition a visible distortion occurs in the surface only when there is adhesive between the inner and outer panels.

Multi-Scale Modeling of Creep of Reinforced Plastics Parts with DIGIMAT
Laurent Adam, September 2013
This paper deals with the prediction of the overall behavior of polymer matrix composites and structures based on mean-field homogenization. We present the basis of the mean-field homogenization formulation and illustrate the method through the analysis of the creep properties of fiber-reinforced structures. The present formulation is part of the DIGIMAT software and its interface to FEA packages enabling multi-scale FE analysis of these composite structures.
Assessment of the Slowdown in Fiber Orientation Evolution in a Center-Gated Disk
Gregorio Manuel Vélez-García, September 2013
Recent modifications to the standard Folgar-Tucker model aim to slow down the evolution of fiber orientation and have been shown to improve orientation predictions in shear flow experiments. However assessment of these models in injection-molded geometries in which shear and extension are both present is very limited. In this work researchers have assessed the evolution of orientation using the newly developed models in a center-gated disk which provides a good injection molding test case combining both shear and extension.
