In this section we will present some modelling developments for various forms of composites. The purpose is not to propose a calculation method - excellent computer software programs exist for that - but to show the broad strength range according to the composite structure, to underline the separate effects of fibres and matrix, and to examine the effects of some service conditions. These examples cannot be used for design calculations.

However, the friction of the Duroid 5813 (about 0.34) was practically unaffected by fibre orientation, unlike the other two composites which gave the lowest friction when sliding was normal to the fibre orientation. This may indicate that in the Duroid 5813 the friction was to a considerable extent determined by the molybdenum disulphide, which was randomly oriented, or by the PTFE, whereas in the epoxy composites the friction was strongly influenced by the fibres themselves. Table 12.5 shows the relationship between fibre orientation and specific wear rate for the Duroid 5813. It should be noted that although the effect of fibre orientation is significant, ail three wear rates are of the same order of magnitude.

The effect of fibre type on the SPF of undyed fabrics of similar constraction is demonstrated in Table 14.2. Cotton and silk fibres offer little protection to UV radiation since the radiation can pass through without being markedly absorbed. Wool and polyester, on the other hand, have significant higher SPFs since these fibres will absorb UV radiation. Nylon falls in between these extremes. One factor influencing nylon and polyester absorbance is the presence of the delustrant TiO, a material that strongly absorbs UV radiation.
