Wear resistant articles are described herein which, in some embodiments, mitigate CTE differences between wear resistant components and metallic substrates. In one aspect, an article comprises a layer of sintered cemented carbide bonded to a layer of iron-based alloy via a metal-matrix composite bonding layer, wherein coefficients of thermal expansion (CTE) of the sintered cemented carbide layer, metal matrix composite bonding layer, and iron-based alloy layer satisfy the relation: $x=\frac{\left(.Math.CTE\mathrm{WC}-CTEMMC.Math.\right)}{(.Math.CTE}$

A composite panel structure of a polymer matrix cote 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.
