Description
L-751 is a laminating grade, 250°F (121°C)curingwovenaramid
prepreg which utilizes a 100% solidsmodified epoxy resin matrix. L-751 is flame retardant per FAR part 25.853 and is suitable for constructionof light weight aircraft componentssuchas air conditioning ducts, fairings,door facings, and interiorpanels. L-751 can be cured over a broad spectrum of times, temperatures, and pressures.
Advantages of L-751
The designeris given a high strength to weight ratio to optimize the design of aircraft components. L-751 uses a 100% solids resinsystem with less than 0.5% volatile content resulting in dense, void free laminates. L-751 has excellent resistance to most fluids encountered in the aerospace environment. L-751 iscompatiblewith many
adhesives and
prepregs utilized in the aerospace industry today, enabling to be co-cured into final assemblieswith ease.
