一种光缆和用于该光缆的纤维增强塑料及纤维增强塑料的制备方法
摘要：
本发明涉及一种通讯网络中光纤接入(FTTx)网络工程的室外系统和室内系统的光缆和用于该光缆的纤维增强塑料及纤维增强塑料的制备方法。一种光缆，它至少在一根光纤上包裹增强套，增强套为纤维增强塑料，增强套外包裹保护套。一种纤维增强塑料，它含有的组分及重量份数为：光固化树脂13～25，纤维纱75～87。一种纤维增强塑料的制备方法，a、将光固化树脂放入70～90℃的恒温箱内恒温1～2小时，b、将光固化树脂和纤维纱放入溶液槽内混合均匀，c、通过拉挤模拉挤为成型杆件，d、将成型杆件置于紫外固化炉中固化0.3～12秒。本发明提高了通讯设施以及用户终端设备的安全防护性能；尤其是缆径细微，曲率半径小，能满足光纤接入(FTTx)网络工程易分支、易接入、施工方便的特殊要求。
摘要（英）：

The invention relates to an optical fiber used in an outdoor system and an indoor system of a fiber-to-the-x (FTTx) network project in a communication network, fiber reinforced plastics used by the optical cable and a preparation method of the fiber reinforced plastics. As for the optical cable, at least one optical fiber is coated with a reinforced sheath which is the fiber reinforced plastics and is externally coated with a protecting jacket. The fiber reinforced plastics comprise the following components in parts by weight: 13-25 parts of light-cured resin and 75-87 parts of fiber yarn. The preparation method of the fiber reinforced plastics has the following steps: a, placing the light-cured resin in a constant temperature cabinet at the temperature of 70-90 DEG C for 1-2h; b, placing the light-cured resin and the fibre yarn in a solution tank for evenly mixing; c, pulling and extruding into a formed rod piece by a pultrusion module; and d, placing the formed rod piece in an ultraviolet curing oven for curing for 0.3-12s. The invention improves the safety protection performance of communication facilities and user terminal equipment; and the optical cable with fine diameter and small radium of curvature can satisfy the special requirements of easy branching, easy access and convenient construction in the FTTx network project.
