3. Laminated Components
A laminated component has two or more layers of glass/carbon cloth. The direction of the fibers in the
cloth is important for the properties for each layer. Extra layers are bonded to areas to give more
strength.
4. Sandwich Structure
Many of the components in the DV 20 E have a sandwich of two skins and a core. GFRP make the
skins and rigid plastic foam makes the core.
The skins must bond to the core of a sandwich structure completely. If the skins do not bond to the
core the component can fail.
5. Bonded Components
A number of components can bond together to make a larger component. Special thick resin bonds
these components together and fills the gap in a joint.
6. Repair Limitations
Repairs which are categorized as 'Class 1' in accordance with Section 51-10, Paragraph 2, may only
be carried out in accordance with a repair scheme which has been approved by the manufacturer.
Such repairs are not described in this Airplane Maintenance Manual.
