The overall objectives of the projects over the six months to 30th June 1990 are:

1. Provide the process data for optimising the strength performance of the scale up pipe process, in particular for HD-Hostalen 5010. Part of this objective is to define, if possible, the conditions under which fibre loadings above 2.5 v/v do or do not give broadly proportionate increases in strength and stiffness (SAFIRE A).
2. Provide input to the scale-up design so that the results of objective 1 can be readily implemented (SAFIRE B).
3. Complete the development of the Mark IV granulation head so that the SAFIRE granules can be made in the relevant fibre concentrations (4 – 10% v/v) for the Olefine polymers of main interest (HD, PP, LD) (SAFIRE C).
4. Continue the testing programme to support objectives 1 and 3, in particular focussing on fracture behaviour. Carry out creep experiments for SAFIRE Hostalen at 2% and 3% v/v at 23 and 60 ^oC (SAFIRE D).
