常规室温下固化聚酯的经验法则是：直线每一英尺的收缩量为1/32英寸（当加强玻纤重量比为25%时）。

A general rule of thumb for conventional room-temperature cured polyesters is 1/32 inch of shrinkage per linear foot when reinforced with 25 weight percent glass content.

此外，作为晶体固化和量的收缩，熔化物的替代品一定会沿着交错的晶体网络流过一段曲折的路程。

Also as dendrites solidify and shrink in volume replacement of melt must flow along a tortuous path of interleaving dendrites.
