一、层压板拉伸试验夹具的现状目前,国内绝缘材料制造和应用单位,在做层压板拉伸试验时,大都用砂布包住试样两端,或将试样两端锯成网纹槽,然后放入拉力机夹具中,虽经这样处理,还是经常打滑,做环氧酚醛玻璃布板拉伸试验时,打 First, the status quo of the laminate tensile test fixture Present, the domestic manufacture and application of insulation materials unit, when doing laminate tensile test, most of the sample wrapped with emery cloth at both ends, or both ends of the sample sawing groove , And then into the tensile machine fixture, although this treatment, or often slippery, do epoxy phenolic glass cloth tensile test, the fight
