L&L InsituCore™ Foaming Core Technology is a family of one-component, heat-activated foaming materials that can be used to create composites with foam core. Placed in a heated tool, the material foams to fill the mold cavity and form net-shape parts without time-consuming machining processes or energy-intensive autoclave operations.
Simplified production process that results in a final lightweight net-shape part or preform with targeted density and strength
Reduced layup time, cycle time, and labor cost compared to traditional processes
Reduced waste from machining operations
Forms and bonds so additional adhesive layers are not required
Reduced number of reinforcement layers for weight reduction

FEATURES FOR HIGH PERFORMANCE
With InsituCore™, internally generated pressure is used to create net shape, 3D parts that are both lightweight and strong in a simple, clean process. Compared to traditional manufacturing and machining methods, these materials enable faster cycle times, a reduction in waste material, and optimized production processes by eliminating secondary machining and assembly operations.
