L&L Products (Strasbourg, France and Romeo, Mich., U.S.) has launched a new FST aircraft interior edge and core filler compound. L&L Reinforce L-9060 is reported to bring a new approach to fill and reinforce aerospace interior sandwich panels by providing a solution to improve the traditionally manual process of other two-component honeycomb panel reinforcements. L&L says the compound addresses process, quality and waste issues for aerospace customers while meeting all industry regulatory requirements.
L&L Reinforce L-9060 is an accurate mixing of two components. Because it requires no hand mixing, it is clean, easy to use and results in no waste. The compound is suitable for automatic metering pumps; equipment to process the cartridge is a standard 400 ml manual or pneumatic gun.
Further, the product has an ultra-lightweight density (0.55 kg) to help reduce the overall weight of aircrafts, for additional CO2 emissions and fuel consumption reduction. L&L Reinforce L-9060 is compliant with FAR/JAR 25.853, which reinforces safety on board and reduces certification cost and it does not contain carcinogenic, mutagenic or reprotoxic (CMR) substances, is REACH compliant and contains no odor.
According to L&L, extrusion of L-9060 is easy, and results in simple application to the honeycomb cells. The material can be spread along edges and easily smoothed with a spatula. L-9060 cures at room temperature and can be milled or sanded 2.5 hours after application. Panels are then reinforced and protected by L-9060, which creates a rigid and impact-resistant reinforcement. L-9060 is also said to create faster curing and more efficient processing methods than the traditional method at a lower cost. In addition, the unfinished two-component cartridge can be closed and kept at room temperature for future use, avoiding unnecessary waste.
Technical information could be discussed with L&L’s team and distributors or found directly on the company’s website. Samples are available on request.
