Crosslamilage

Crosslamilage is a proposed class of wood-based composite materials that combines elements of cross-laminated timber (CLT) with laminated veneer lumber (LVL) approaches to form panel composites intended for structural and architectural use.

In this concept, layers of veneer or thin boards are arranged with alternating grain directions and bound with high-strength adhesive, then consolidated under heat and pressure to produce a panel with improved dimensional stability, shear strength, and impact resistance relative to conventional LVL or plywood.

Manufacturing involves preparation of veneer sheets, stack-up with grain angles typically 0/90 degrees, cohesive adhesive (e.g., urea-formaldehyde or phenol-resin), and hot-press curing; optional surface treatments for fire retardancy or environmental resistance.

Applications include building envelopes, interior partitions, flooring underlayers, and furniture components where mechanical performance and reduced warpage are desired.

Properties include anisotropic strength with high stiffness along principal axes; improved resistance to cupping; potential for better thermal and acoustic performance; fire performance depends on treatment; moisture sensitivity remains a consideration.

History and etymology: the term has appeared in limited technical discussions and speculative proposals; it is not standardized in major standards organizations.
