A composite panel structure of a polymer matrix core sandwiched by metal layers is described. The polymer matrix comprises 1-30 wt % fluoropolymer and 70-99 wt % of a flame retardant mineral. The fluoropolymer may be polyvinylidene fluoride (PVDF) with a high limiting oxygen index, which confers fire resistance properties to the polymer matrix and the composite panel structure. The composite panel structure may be used on the exterior of buildings and may fulfill building code requirements for the polymer matrix core being noncombustible as determined by ASTM E136 and CAN/ULC S114 compliance.

A melt transferred imaged coated product and process for decorative simulated wood, metal or stone-like patterns especially useful on treated non-sealed, non-anodized metal-resin composites for interior signage and display, is described. The product exhibits excellent adhesion bonding between the aluminum surface and the transferred-carrier film that contains the dry-ink image that is deposited on the aluminum surface. The aluminum surface is prepared by conventional pre-etching means, coated with a suitable thermosetting resin and then optionally primed with an adhesive prior to melt transfer of the image. The final surface finish coating is protected with an additional transparent adhesive backed polymer film.
