聚甲基丙烯酸甲酯（PMMA）透明度较好。采用PMMA为原料，通过预制聚合物光纤棒，拉制成丝，排板热压方式制备塑料光纤面板。结果表明：随保温时间的增加，塑料光纤面板成像性能呈现先提高后降低的趋势，最佳保温时间为6 h，比理论保温时间多2 h。调整聚合物光纤棒的预制工艺，制备表面干净的复丝，可以减少杂质对复丝边界的影响，降低热压压力，减少下压刻度，制备成像清晰、完整的塑料光纤面板。该方法能够减小光纤面板的生产成本和质量较轻。

Poly(methyl methacrylate) (PMMA) has good transparency. Using PMMA as the raw material, plastic optical fiber panels were prepared by prefabricating polymer fiber rods, drawing them into fibers, and then hot-pressing them into panels. The results showed that as the holding time increased, the imaging performance of the plastic optical fiber panel first improved and then decreased. The optimal holding time was 6 h, which is 2 h longer than the theoretical holding time. Adjusting the prefabrication process of the polymer fiber rods to produce clean-surfaced multifilaments can reduce the impact of impurities on the boundaries of the multifilaments, lower the hot-pressing pressure, and decrease the pressing scale. This leads to the production of plastic optical fiber panels with clear and complete imaging. This method can reduce the production cost of fiber panels and result in a lighter product weight.
