Finishing allows structural core materials to be shaped and engineered to meet specific application requirements — whether driven by processing method, design complexity, weight targets or surface quality. With options including grooves, perforations, kerfs and scoring patterns, each finish serves a defined purpose and can significantly improve manufacturing efficiency.
Selecting the right finish enhances resin flow, bonding behaviour and laminate consistency, while reducing waste, improving curvature capability and, in many cases, eliminating the need for external flow media.
Available Finishes
Plain Sheet
Standard flat-sheet core for general applications and hand lamination.
Perforated (PF)
Improves air evacuation and resin flow during infusion processes.
Grooved (GRC)
Machined flow channels for controlled resin movement and faster processing.
Grooved & Perforated (GPC)
Combines grooves and perforations to ensure reliable, even flow across large or complex panels.
Grid-Scored with Scrim (GS)
Small blocks held by scrim allow the core to easily conform to curved or compound surfaces.
Double Contour
Deep, flexible scoring patterns that provide maximum conformability, enabling the core to wrap smoothly around tight radii, complex geometries and highly contoured shapes.
Every industry has distinct performance, compliance, and manufacturing requirements. ATL’s in-house chemists and engineers develop and refine epoxy systems, adhesives, and core materials to meet the specific demands of marine, defence, aerospace, automotive, industrial, civil, architectural, and sporting applications — ensuring every product delivers optimal strength, efficiency, and durability.
Yes. ATL offers custom formulation and process engineering support to align material performance with your production requirements — whether infusion, hand lay-up, lamination, bonding, or CNC-routed panel construction. Our technical team collaborates closely with customers to deliver precision-matched resin systems and structural solutions for unique applications.
Absolutely. ATL operates under an ISO 9001:2015-certified quality management system, with selected materials approved by DNV for use in structural and high-load applications. Every ATL system is manufactured to exacting standards of performance, consistency, and traceability to meet the demands of defence, industrial, and advanced engineering environments.
ATL’s epoxy systems, structural panels, and composite cores are engineered for high strength-to-weight performance, dimensional stability, and fatigue resistance. These attributes make ATL materials ideal for large composite assemblies, modular structures, and precision-engineered components where long-term strength, weight reduction, and reliability are essential.
Yes. ATL is committed to advancing sustainable composite technology, offering USDA-Certified Bio-Based epoxy systems and environmentally conscious materials that reduce waste, extend service life, and minimise environmental impact. Our ongoing R&D focuses on improving sustainability without compromising structural integrity or mechanical performance.
Choosing the ideal composite system depends on your structure’s design, load requirements, manufacturing process, and environmental exposure. ATL’s in-house engineers and chemists provide tailored advice to ensure the correct combination of resin, core, adhesive, and surface technology for your project.
