1 Scope

This standard specifies the test method for peel strength of the sheet surface layer sandwich structure. This standard applies to fiber-reinforced plastic sheet for the surface layer of rigid, rigid-foam core sandwich plate structure, others such as aluminum, steel And other rigid board for the sandwich structure of the surface layer, or plate sandwich structures other core materials may also refer to adopt. Note 1. This standard compared with GB/T 1457-2005, which applies only to the flexible panel. Note 2. If the sandwich panel bending stiffness (EI) is greater than 3.09kN · mm2/mm width, that is about the glass plate thickness greater than 1.18mm, the thickness of aluminum Greater than 0.81mm, plate thickness greater than 0.57mm, more according to the standard test method for effect.
