Abstract
In previous chapters, the properties and fabrication techniques of a single skin composite of GRP, capable of being used for small components as well as large folded plate structures, have been discussed. If it is necessary to increase the stiffness of the overall cross-section of the composite or the individual laminates, a sandwich construction consisting of the reinforced polyester composites bonded to a low density core may be used. The face then generally supports the bending moments and axial forces within the composite cross-section and the core takes the majority of the shear. The core may be of low density polymer and four types of foam which are not exhaustive but which are used in the construction industry and which will be considered in this chapter are:
-
(a)
rigid polyurethane;
-
(b)
phenolic;
-
(c)
polyvinylchloride;
-
(d)
polystyrene.
