DESCRIPTION
Presentation by Brian Bower and Raymond Arai of Owens Corning at CAMX on October 15, 2014. Residential oil tanks have been dominated by steel tanks for decades, but #composite replacements redefine design while better protecting the #environment and slashing part weight for easier installation and maintenance. Material suppliers and composite molders are eager to meet spreading legislation banning the use of steel tanks, and propose solutions improving the design, durability and performance of residential heating oil tanks. By adopting a closed mold manufacturing solution and therefore the use of continuous filament mat (CFM) preforms, the result is higher consistency and increased productivity.
