PURPOSE:To provide a composite fiber assembly having such thickness as to be consistently high in mechanical strength despite varying in its weight and good in press formability. CONSTITUTION:The composite fiber assembly is such that numerous glass fibers including those oriented in the thickness direction are mutually, partly bound through high-density polyethylene and there are numerous fine voids throughout. The thickness T (mm) of the assembly, depending on its weight W (kg/m<2>), satisfies the following relationships: when 0.4<=W<=0.9, 4W-0.5<=T<=5W+1, and when 0.9W<=1.7, 6W-2.3<=T<=8W-1.7. |
