FRACTAL PHENOMENA OF THE FLEXUAL STRENGTH FOR GLASS FIBER REINFORCED POLYESTER AGED BY XENON ARC LAMP ACCELERATING
摘要
Abstract
Unsaturated polyester and glass fiber reinforced polyester were accelerated aged by the xenon arc lamp, the bending strengths are measured. It is found that the relationship of the bending strength and the ageing time is the fractal phenomena. The fractal dimensions of the bending strength are calculated by means of changing the observing scale, the results are the polyester fractal dimension is 1.24, that of glass fiber reinforced polyester containing calcium carbonate is 1.12, and the glass fiber reinforced polyester' s is 1.08. The complexity of the ben ding strength according to the polyester, glass fiber reinforced composite containing calcium carbonate, glass fiber reinforced composite sequence is degressive under accelerating aged by the xenon arc lamp.关键词
