“…7.a (Slip)). Cogswell et al [88] showed that such slip is more important when the plies are stacked with different orientations because of thicker resin-rich areas at the interface, easing the inter-ply slip while reducing fiber-fiber friction [85,88,89]. This type of deformation is therefore only dependent on the shear viscosity of the neat matrix [85].…”

“…For the case in which the stress is linear in D the constitutive equation was formulated by Rogers [9] and Kaprielian and O'Neill [10]. For the general case, by standard results in the theory of tensor representations (see, for example, Zheng [11]), and using the identities (20), τ can be expressed explicitly as…”

“…Several authors have used the simplified flow equations of the I.F.R.M. theory to obtain approximate solutions for processing problems with continuous fiber reinforced thermoplastics of the type mentioned in the previous section (34)(35)(36). It is expected that this constitutive model will provide the capability to model all of the important deformation mechanisms (except for resin percolation) in forming analysis.…”

A literature survey is presented on sheet‐forming methods and mechanisms for continuous fiber reinforced thermoplastics. The diaphragm forming process is shown to be one of the more promising fabrication routes for complex‐curvature structures. The primary deformation mechanisms involved in the sheet‐forming processes are identified and discussed. Earlier approaches to develop mathematical models either have been kinematically based or have treated only one of the primary deformation mechanisms. A promising constitutive model for the highly anisotropic behavior of the composite at forming temperature is examined. The composite sheet is assumed to behave as a transversely isotropic Newtonian fluid that is both incompressible and inextensible in the fiber direction. The second section of the paper treats the experimental development of the polymeric diaphragm forming process for thermoplastic composites. The viscoelastic properties of the diaphragm material are characterized by dynamic mechanical analysis. The rate sensitivity of the phenomenon of shear‐buckling during forming of certain cross‐ply and quasi‐isotropic composite laminates is investigated, using a shallow female mold. Finally, the interface condition between the diaphragm and the composite during forming is examined.
