RESEARCH REGARDING THE MOMENTS REGRESSION REALTIONS AT DRILLING MINERAL COMPOSITE MATERIALS WITH 3% CONCENTRATION OF GLASS FIBER

Abstract

The paper presents theoretical and experimental researches on cutting through drilling composite minerals products having concentration of 3% fiberglass resulting mathematical relations regression forces and moments depending on the parameters of the drilling process. The purpose of the research is to prevent delamination of the composite mineral fiber, highlight contraction phenomena that occur as a result of increased temperature in the process of drilling and also to determining the processing errors. The objective of the research is that during drilling operation to obtain a balance that does not affect material properties of composite mineral and lead to composite minerals for civil and industrial structur es adapted to the conditions of use with high levels of reliability with high resistance of the spatial stress demands like earthquakes.
