Lytex® Parts used on Commercial Jets

Lytex 9063 glass reinforced epoxy ESC® and Lytex® 4149 carbon fiber reinforced epoxy ESC® are both qualified by North America's leading producer of commercial airliners. Quantum Composites material is used extensively in tertiary and secondary structure applications where net shape compression molding can provide cost and weight reduction benefits over aluminum and other metals including cost reduction over prepreg materials. Aircraft companies have increased their reliance on compression molded Lytex® components as overall composite usage has increased in the next generation aircraft with higher carbon and glass fiber composite content.

The world's leading airframers use hundreds of different parts, molded from Lytex for secondary and tertiary structure applications. These parts are on virtually every commercial jet manufactured and assembled in the USA, from single aisle short- and long-haul variants to the latest generation of composite intense twin aisle airliners.

Part size and geometry vary from large triangular-shaped fairings measuring 43" x 22" to small brackets a few inches long.  Lytex is usually chosen because of its much lower part cost versus a prepreg part. A key benefit that Lytex offers is the ability to easily mold in ribs, bosses and changes in thickness. Thicker areas, for hinges and hard point attachments, are easily molded into the part. When using prepreg laminates, variations in part thickness is labor intensive and more expensive.
