EVALUATION METHOD OF GRANULAR FIBER SPRAY CONDITION, AND GRANULAR FIBER SPRAY EXECUTION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a technology capable of evaluating simply, especially confirming just before execution on an execution site, relative to in-material exfoliation of a fiber layer formed by granular fiber spray.;SOLUTION: An evaluation method of a granular fiber spray condition includes a step (step A) for forming a fiber layer 30 by spraying granular fiber to a base 20 together with a flocculant, a step (step B) for installing an extraction tool 10 from the fiber layer 30 surface, and a step (step C) for measuring a tensile load when in-material exfoliation is generated in the fiber layer 30 by pulling the extraction tool 10.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2018,JPO&INPIT
