The present disclosure teaches hybrid metal/composite battery trays. The hybrid trays, which may be deep trays, may be made of a metallic (e.g., steel or aluminum alloy), cruciform-shaped partial tray with four polymer/fiber composite corner inserts that are attached to four recessed corners of the partial tray. Overlapping bond joints may be co-molded. Overlapping metallic bond surfaces may be pre-treated by laser ablation and/or by plasma treatment, to increase the bond strength between overlapping metal and polymer/fiber composite surfaces. Mechanical interlocking features may further be used to increase joint strength. An intermediate composite layer (made with short, chopped fibers) having an intermediate Coefficient of Thermal Expansion may be inserted in-between the metallic partial tray and the polymer/fiber composite corner inserts to reduce residual thermal stresses that develop during cooldown from a high temperature curing step. Rounded, convex fillets may also be used at square corners between the dissimilar materials.
