Accurately analyzing and predicting the mechanical behavior of components made from fiber-reinforced thermoplastics is complex because the fibers are individually oriented during injection molding. Finite-element analysis often uses isotropic material models. Results can be improved if local fiber orientations are considered with anisotropic material properties. This analysis process and a practical application are presented.
This presentation describes a new class of resin aromatic thermosetting copolyester (ATSP) which shows high temperature stability flame resistance and adhesive properties. Carbon fiber helps in stabilizing the nemetic phase in the liquid crystalline melt. The morphology of novel aromatic thermosetting copolyester in the presence of carbon fibers will be described and the presence of crystallinity which helps in improving the fracture toughness of these structures will be discussed.
A family of new epoxy resin systems will be introduced that meet the requirements of automotive production and performance. Also an outlook will be given about what one can expect from a dedicated development partner and supplier.
A novel algorithm to measure fiber-length distribution was implemented. The fiber-orientation distribution within a long- fiber thermplastic (LFT) charge was measured using micro- computerized tomography (?-CT). Using a 3D numerical- simulation package Moldex3D the influence of the initial fiber orientation within an LFT strand was evaluated.
A methodology for the rapid adoption of long-fiber thermoplastic (LFT) composites in the industry is outlined. Examples of recent metal-to-composite conversions are given to illustrate the innovation process.
Polymer composites are the key for lightweight construction and enable automotive producers to reduce fuel consumption and emissions and fulfill governmental requirements. Today processes and materials are available to produce polymer composites with an excellent balance of cost and performance. This tutorial will focus on processing technologies for the production of polymer- matrix composites. Advantages and challenges of the manufacturing of thermoplastic and thermoset composites parts will be highlighted.
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.
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.
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.
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.
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.
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.
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.
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.
