Forensic Clues: Fiberglass Failure
Safety Engineering Resources has had the opportunity to learn a great deal about using fiberglass in structural applications, which are simply applications that must support some sort of load. Using fiberglass as a structural material was brought about by the advances made by organic chemists in recent decades in the field of plastics.

Design Defect Failure Analysis of Water Shut Off Valve
By: Dr. Thomas Read
When this type of valve is open a rubber seal around the valve stem prevents leaking. In this case, the poly acetate stem deteriorated due to the presence of hot chlorinated water This allowed water to leak out. Over time the leak rate increased.

Glass Coffee Pot Failure Analysis: Thermal Shock Failure Of Borosilicate Glass Coffee Carafe
By: Dr. Thomas Read
The fatigue failure initiated on the outside bottom where the carafe had been scratched with the abrasive scrub pad. As a result of cyclical thermal shock (between 195°C and 15°C), the cracks grew progressively till it reached a critical length. Glass thickness at the origins is approximately 3 mm. One failed after 12.
