The SPE Library contains thousands of papers, presentations, journal briefs and recorded webinars from the best minds in the Plastics Industry. Spanning almost two decades, this collection of published research and development work in polymer science and plastics technology is a wealth of knowledge and information for anyone involved in plastics.
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.
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.
Thermoset-based sheet-molding compound (SMC) with an unsaturated polyester matrix was used to develop a new glass-fiber reinforced material. Specimens were cut from newly molded SMC plates and subjected to 3-point flexure and tensile tests. FEM models of an SMC seat-connection element have been generated and analyzed. then compared with physical testing results.
CFRP technology is currently being extended to structural fittings and future use of the technology for automotive applications is under investigation. The design and production of such products is typically a manual process. The result of one such design method for 3D parts has been analyzed using analytical models to understand the role of resin and fiber in these designs paving the way for the use of materials more suitable for mass production than the well established epoxy 914/T300 composite. It was concluded that the design principle investigated is effective in maximizing tension in fibers and compression in the resin while minimizing shear in parts that are subject to out-of-plane loads. Good agreement with bending and shear tests was found.
