β¦ Synopsis
Luzzati's method for the evaluation of multiple X-ray small angle scattering has been revised and completed. Under the usual experimental conditions multiple scattering occurs practically in all cases in which the produce of the average pore size (in A) and the volume fraction of pores is larger than 10. The information obtainable from multiple scattering can, under appropriate experimental conditions, be as complete as that from single scattering. Absolute measurements are easier to carry out with multiple scattering than with single scattering.

The electron microscope (both in the scanning and transmission modes) was used to examine the topography of both wet (60% HNOs, 118Β°C) and dry oxidized (air, 700Β°C) fibers as well as fracture surfaces of composites made with treated and untreated fibers.
