ABSTRACT This invention discloses sandwich panels, i.e., laminates which comprise two metal sheets with a filled, reinforced resin core between a bonded metal sheets, which are useful for structural and other uses. This invention discloses combinations of metal skins, resins, fillers, and reinforcement bonded together in the sandwich structure to provide a laminate having a flexural modulus of at least 2.5 million psi, a rigidity index of at least about 2,000 and other unique properties which enable the laminates to be particularly useful for thin wall trailer body construction, as well as other uses. This invention discloses a rigidity index property for sandwich structures and panels and a falling ball impact test, both of which are used to characterize the properties of sandwich laminates. This invention discloses methods of making the above sandwich laminates. This invention also discloses a means for joining sandwich laminates and panels which is particularly useful in the trailer body construction as well as other uses. S-005823.001/tgd-c
