This week the “Meet the Team” series introduces George Ritter of the EWI Materials group. George specializes in the areas of adhesives and plastics. George has spent over 30 years in industrial research environments, with much of that time spent on structural adhesives bonding applications. Please feel free to contact George if you have any […]
Read MoreOn December 10th at 10:00am EST, EWI Principal Engineer George Ritter will be presenting an online webinar, Adhesives 201: Structural Adhesives, The one-hour session will provide an introduction to structural adhesives from an engineering perspective and is of value to R&D professionals who are responsible for selecting or formulating adhesives in assembly markets, engineers who build, design or specify […]
Read MoreWe have had recent interest in looking at methods to join thermoplastics and thermoset composites to titanium from both the aerospace and medical communities. Generally, thermoset composites have higher temperature resistance than thermoplastic materials and must be bonded because they do not melt. Thermoplastic materials are easier to mold and will flow when heated. Therefore […]
Read MoreIf you’re wanting to learn more about plastics welding, check out the recently published American Welding Society’s (AWS) Welding Handbook, 9th edition, volume 5. EWI’s George Ritter and Matt Short, along with colleagues from other institutions, authored chapter 8, “Plastics,” providing a timely rewrite of the 1995 edition. George Ritter also served as committee chair. This section on plastics welding was […]
Read MoreOn behalf of EWI, I’d like to thank the team of volunteer judges for the annual State Science Day competition May 11, 2014, at which we granted the EWI Award for the outstanding student projects in the field of materials science and engineering. There were two grade categories of 7th-9th and 10th-12th with 1st, 2nd, […]
Read MoreThis is a Technical Brief written by Dr. George Ritter, Principal Engineer in our Materials group. George can be contacted at 614.688.5199 or [email protected]. You can view George’s bio here. If you are interested in this article, you may also be interested in another article on lightweighting. Composites as Structural Materials Composites provide directed, purposeful stress management […]
Read MoreGot a tough combination of molded components? Normally we weld, but sometimes the two materials are welding incompatible or the welding conditions are too extreme in temperature or time for the size of the part or complexity of the design. In that case, the option is to bond the materials. Bonding thermoplastics is a little tricky […]
Read MoreLightweighting is a process of replacing a material with another to reduce weight while maintaining performance. Automotive reduces weight to improve fuel efficiency primarily since the payload itself is fairly constant. Aerospace uses lightweigting to increase payload and range. In that respect, the advantage of lightweighting for heavy manufacturing is closer to that for the […]
Read MoreMost of the work I do involves putting things together down in the lab. If you are having problems putting things together and keeping them that way, give me a call or email. If we can’t getting you going again with a phone call, we can do a bit of forensic work here to analyze […]
Read MoreThe State Science Day competition was held this past Saturday at the St. John Arena and hosted by the Ohio State University. EWI and EMTEC sponsored the Edison Center Materials Science and Engineering Awards for outstanding student projects in the field of materials science and engineering. There were two grade categories of 7th-9th and 10th-12th […]
