Best Combination of DMA, DSC, FTIR for Optimal Material Analysis

December 5, 2018 (5:30-8:00)

Special Chem
Presenter: Jeff Jansen

You often have to mix multiple tools (DSC, DMA, FTIR, TMA...) to either characterize your materials or solve complex formulation or processing issues. It is important to understand which tool to use, and how to complement data from these multiple techniques for better analyses.

This webinar will cover commonly empolyedd material characterization techniques such as FTIR, DSC, TGA, GPC and DMA, and highlight when and how to use these techniques to help solve problems. Additionally, the webinar will highlight when you might need to analyze data from multiple methods to find the answer to your question.

This talk will highlight some theory behind these techniques, and will reinforce the concepts through real life case studies. This webinar will be great for young and experienced engineers, and will help you identify potential solution faster.

Thermal Analysis in Failure and Compositional Analysis

December 6, 2018, 10 AM CDT
Presenter: Jeffrey Jansen

Thermal analysis is an important group of tests used in the analysis of plastics and other polymeric materials. It consists of a family of well-established techniques that evaluate material properties as they change with temperature, time, and ambient environment under conditions of thermal programming. The results of thermal analysis tests provide qualitative and quantitative information about the material being evaluated. In particular, this information is important to address plastic failures or in characterization of the material composition and physical properties.

The upcoming webinar on thermal analysis will introduce the four primary techniques:

Design and Processing Considerations for Long-Fiber Thermoplastic Composites

December 13, 2018, 12 PM CDT
Presenter: Erik Foltz

Engineers and designers are constantly looking for ways to improving part performance while driving down cost. The development and integration of long-fiber thermoplastics composites into semi-structural parts has allowed many companies to achieve more robust performance in their plastic part design, and take full advantage of light-weighting structures, as compared to short-fiber reinforced materials. However, in order to optimize the performance of these structures, extra attention needs to be given to how the parts are manufactured. Optimizing the part wall thickness, avoiding excessive fiber attrition, developing desirable fiber orientation, and minimize the residual stress in the material become critical to achieve the full potential of these materials.

This webinar will discuss the importance of plastic part design, tooling, and processing on the end performance of discontinuous reinforced composites. Both glass and carbon fiber materials will be discussed, and how to take full advantage of both reinforcement types.

Creep Failure of Plastics

February 14, 2019, 10 AM CDT
Presenter: Jeffrey Jansen

Creep is the tendency of a polymeric material to deform permanently under the influence of constant stress, as applied through tensile, compressive, shear, or flexural loading. It occurs as a function of time through extended exposure to levels of stress that are below the yield strength of the material. Given sufficient time, this can lead to creep rupture, the failure within a material as a result of continuously applied stress at a level below the short-term tensile strength. Plastic materials are particularly prone to creep rupture through exposure to static stresses, and a recent study indicates that 22% of plastic failures are associated with creep.

The relatively high frequency of creep failure is linked to the widespread lack of awareness and understanding of the effects of time on polymeric materials, particularly at the design stage; the unique difference in time dependence between polymeric materials and metals; and the increasing use of plastic materials in diverse applications with longer time demands.

The concept of creep is extremely important to manufacturers and designers of plastic components.

Basic Rubber Technology

April 11, 2019, 10 AM CDT
Presenter: Jeffrey Jansen

This webinar will introduce the attendees to the basics and most important topics related to thermoset rubber compounds. About 15 billion kilograms of rubber are produced ever year. Rubber finds its way into wide range of applications in the automotive, medical, appliance, electrical, and chemical industries. As a class of materials, rubber has many useful properties because of its unique molecular structure. These include being soft and relatively flexible, high ultimate elongation coupled with good elastic recovery, useful over a wide temperature range, and good chemical resistance.

A part of the presentation the following topics will be covered:

Plastic Part Failure: Analysis, Design & Prevention (UW-Milwaukee)

October 15-17, 2018
Presenters: Jeffrey Jansen, Dr. Antoine Rios, Dr. Javier Cruz, and Erik Foltz

Dive into a broad range of topics essential to understanding and preventing plastic failure. The most efficient and effective approach to plastic component failure is performing a systematic failure analysis following a scientific method. Someone once said, "if you don't know how something broke, you can't fix it," highlighting the importance of a thorough understanding of how and why a product has failed. With emphasis on practical problem-solving techniques, the course will utilitze case studies to comprehend key aspects of plastic failure and prevention. Gain a better understanding of why plastic components fail, and how to avoid future failures by applying the knowledge learned.

Ductile to Brittle Transitions in Plastics

October 18, 2018, 10 AM CST
Presenter: Jeffrey Jansen

The objective of a failure investigation is to identify the mechanism and cause of the failure. The characterization of the failure mode such as, fatigue, overload, environmental stress cracking, etc... is often straightforward through fractographic methods. However, the determination of the cause of the failure is in many cases less apparent. Plastic materials are utilized in many applications because of their unique property set, including their ductile response to applied stress. This ductility is associated with the viscoelastic nature of polymers and is attributed to their unique molecular structure. In spite of that inherent ductility, most plastic components fail through one of the many brittle fracture modes. Experience has shown that less than 5% of failures are associated with ductile overload. The remainder represent brittle fractures of normally ductile materials. Thus, within evaluations of plastic component failures, the focus of the investigation frequently turns to identifying the nature of the ductile to brittle transition. This relatively brittle response to stress is evident through the examination and characterization of the fracture surface morphology.
