Composite Mat Locking System Development & S7 Pin Redesign
Lightweight composite mats could slide apart under traffic. The locking system, and a later S7 pin redesign, had to make the roadway behave as one unit.

Installed mats humped in the afternoon heat and curled overnight. The cause was differential thermal expansion, not ordinary molding warpage.
Almost immediately after commercial production began, customers reported that the new composite mat was too slippery for foot traffic.

Traditional timber access mats performed the job, but they rotted. The objective was a reusable composite mat that would resist rot and match wood in the field.

Turn an unpredictable hot-forming process into repeatable commercial production of extruded pipeline outlets and split tees.

A U.S. manufacturer of heavy-duty composite access mats was losing production to dimensional distortion. The recovery corrected the molding process instead of machining the symptom.
