In terms of process of the resin this marks an important watershed: before gelation the system is relatively mobile, after it the mobility is very limited, the micro-structure of the resin and the composite material is fixed and severe diffusion limitations to further cure are created.
Degree of Cure Test Curing is a term in polymer chemistry and process engineering that refers to the toughening or hardening of a polymer material by cross-linking of polymer chains, brought about by chemical additives, ultraviolet radiation, electron beam or heat.

It is reported that one Russian institute is using a new process called
step-by-step rolling plus roller stretch, in which the mill is characterized by simple structures, small
dimensions, low noise and vibration, and no residual material during deformation process.

Abstract.
The XRD paettern of the resulting powders : (a) HAp powder, (b) HAp powder added Acetic acid 0.05 mol·dm-3, (c) HAp powder added Succinic acid 0.05 mol·dm-3 and (d) HAp powser added Citric acid 0.05 mol·dm-3 The FT-IR spectra of the resulting HAp powders were attributed to chemical groups in the HAp structure.

The changes in surface chemistry can be related to the change in particle surface morphology.
The reactions involved in this transformation are: 10 CaF2 + 6 H2PO4 = Ca10(PO4)6F2 + 18 F + 12H + 10 CaF2 + 6 HPO42 = Ca10(PO4)6F2 + 18 F + 6H + These reactions suggest that the molar ratio of F released into solution to the F incorporated into the apatite structure is 9.
