Material Answers conducts failure analysis and accident
investigations concerning materials and/or processes.
Our projects have encompassed
identification of root cause; exploration of failure mechanisms;
evaluation of material composition; site inspections;
assessment of environmental factors such as stress,
temperature, and chemical attack;
and design and performance of accelerated testing programs.
Investigation of Reactor Accident
During routine startup of a chemical reactor an overpressure
occurred that resulted in a steam release and severe burn
injuries to the operator. Several potential root causes for
the release were investigated.

Defect Reduction in Plastic Sheet Extrusion
A manufacturer suffered low process yields due to the presence
of "spots" or "gels" in a plastic sheet product
made from a blend
of polyethylene with a ethylene-propylene copolymer.

Reduction of Wear in V-Belts
V-belts for motor drives in high torque applications
were wearing and failing at an unusually high rate.
The V-belt manufacturer requested recommendations for
process changes which would yield improved wear resistance.
