Fig. 2: Composite mould for composite parts
of ParaGlass/5 fabric. Mould construction begins with a 0.3-mm gelcoat layer to produce a hard, smooth and durable moulding surface. This is followed by three reinforcing layers — typically a 1.3-mm thick ply of chopped strand mat and vinyl ester (VE), a 1.5-mm thick ply of chopped strand mat and specialized tooling resin system (i.e. Nord Composite’s Zero Shrink or CCP’s OptiPLUS) and a 1.3-mm thick ply of chopped strand mat and VE. This is followed by two layers of ParaGlass/5 with the neat resin (VE) of the second layer applied at a right angle to that of the first layer. A final ply of 0.5-mm thick chopped strand mat and VE is then applied.
3D
The ParaGlass 3D glass fibre material is woven from E-glass yarn and consists of two deck layers connected by vertical yarns. The z-directional yarns, which are woven through the deck layers, tie them together in an integral sandwich structure, and the deck layer preforms absorb the resin. As the fibres are impregnated, the fabric rises to a preset height and, in a single step, a complex construction is created with z-axis fibres that pick up the shear and compression/buckling loads much as a foam or honeycomb core would. This allows significant weight reduction without sacrificing stiffness-toweight and strength-to-weight ratios.
Feature Marine
Final advantage
If the mould needs to be cooled or heated, the ParaGlass provides a space to introduce cold or heated water (recommended only with an epoxy resin system). Even without an integrated cooling system, the tool reduces preparation time by quickly returning to ambient temperature for production even when stored in a cold environment. Since the entire tool is constructed entirely of glass and resin, the tool is not susceptible to delamination. n
