Until the mid-1970s, compression testing of composite materials received relatively little attention. Up to that point it, had generally been assumed that the compressive stiffness was approximately ...

Composite materials, whether for use in high performance structures or in commodity applications, present many unique mechanical testing problems. Thus, this two-day seminar will be directed toward ...

Many composite structures are assembled with mechanically fastened (“bolted”) joints. Structural analysis of these attachments requires a linked set of design properties that are generated by D30 test ...

The National Electrical Manufacturers Association (NEMA) has published ANSI C29.11-2012, "American National Standard for Composite Insulators—Test Methods" The National Electrical Manufacturers ...

ALBUQUERQUE, N.M. -- Researcher David Moore holds a rectangle of hard carbon composite material, smooth with a faint woven pattern on its surface. The sample shows normal wear and tear until he turns ...

The EPA is proposing to update several voluntary consensus standards in the Agency's formaldehyde standards for composite wood products regulations and proposes test methods that will provide ...

Dan Crothers, managing director at Seward, said the machine was launched in response to increased market demand for sample preparation methods suitable for larger volume composite samples. “While not ...
