Lentus Composites: Enabling Technologies

You are here: Home \ Lentus Composites

Lentus Composites designs, manufactures and qualifies a broad portfolio of composite products using a range of manufacturing technologies including autoclave/pre-preg, RTM and resin infusion as well as being experts in the field of filament winding.

The main product areas for Lentus  include pre-preg/autoclave and RTM processes for panels, enclosures and structures, filament wound products such as hydraulic accumulators and pressure vessels, rings/tubes/sleeves, containment sleeves motor/generators, transmission shafts, actuation rods and struts, medical components, energy storage flywheels and other structural elements.

Lentus has a focus on process control and repeatability for the manufacture and traceability for producing composite products.

The filament winding machines not only control the winding patterns and layers but also control the surrounding process parameters such as temperatures, resin life, tensions and the environment. In order to make a good composite consistently it is important to follow a process with the machine movement, the process and environmental factors and a time line all being strictly adhered to. Lentus has experience of winding with a wide range of “wet” resin systems, pre-preg winding as well as creating resin formulations using additives such as nano-particulates and toughening agents.

Shop floor data capture systems pull together all of the engineering data for each products.

Manufacturing is controlled under strict quality systems and business processes. These are currently audited to ISO 9001:2008. Lentus has extensive inspection and testing facilities enabling mechanical testing to take place for product validation and qualification as well as physical characterisation of the composite and process along with NDT and dimensional inspection.
