Abstract

The second section of a review, commenced in the previous issue, is presented, covering the subject of carbon fibre and glass fibre hybrid reinforced plastics (cghrp). The existence of a ‘hybrid effect’ is still the subject of some controversy, although a negative synergism has been reported in fracture at high interdispersion of the two fibres. Some attempts to quantify the residual thermal stresses from curing have been made, but these do not correlate well with the observed hybrid effect. A discrete burst of acoustic emission has been reported on the transfer of load to the glass fibres, coincident with the load drop associated with failure of the carbon fibres. The conclusions of the previous review would appear to be still valid. An outline of the areas of ignorance is included.

      Discontinuous unidirectional carbon/epoxy prepreg plies were laid up in blocks in an overlapped configuration which demonstrated some non-linearity but the strain at failure was still lower than conventional unidirectional material [35]. The performance and failure strain were governed by the degree of dispersion of fibers in the hybrid FRP [24,36]. In addition, minimal bond strength between carbon and glass layers was required to achieve pseudo-ductility [25].

      However hybrids usually show an unfavourable major load drop at the failure of the low strain constituent if the level of dispersion is too low and/or the volume fraction of the low strain fibres is too high. A few reviews [19–23,3] summarise the extensive literature on hybrid composites accumulated since the early 1970s. Based on the literature, the most successful approach is the interlayer or layer-by-layer hybridisation partly for its simplicity, as intimate mixing (or intermingling) of different continuous fibres providing high dispersion is currently only feasible on a small scale.

      Mixing the fibres can be done in different levels such as intermingled continuous fibres [16], intermingled aligned short fibres [17], interlayer or sandwiched layers [18] and intralayer [19]. Glass/carbon [4,13,18],carbon/carbon [20–22] and polymer fibre/carbon [19,23] are some of the common material combinations used in hybrid composites. Four different types of failure processes have been recognised for Uni-Directional (UD) hybrid composites [24,25]: 1) premature high strain material failure after the first crack in the low strain material, 2) catastrophic delamination of the low strain material from the high strain material after the first crack in the low strain material, 3) fragmentation of the low strain material and 4) fragmentation of the low strain material followed by limited dispersed delamination.

      Our intention is to use various high stiffness (low failure strain) and high strain (lower stiffness) carbon fibre/epoxy prepregs in thin format to address this issue and fully exploit the benefits of hybridisation for progressive, pseudo-ductile failure. The extensive literature on hybrid composites accumulated since the early 1970s is summarised in a few reviews [15–20]. The most practical approach based on the literature is the layer-by-layer or interlayer hybridisation, as intimate mixing of individual continuous fibres (also called intermingling) is not feasible on an industrial scale at the moment.
