    • PROBLEM TO BE SOLVED: To provide a cured article wherein crack widening, fragment falling or excessive deformation can be highly inhibited by compounding an organic fiber to which a shape enabling excellent physical adhesion to the cured article is imparted by a simple, low-cost, thermal or mechanical processing method, although the organic fiber, even simply added to a hydraulically cured article such as cement concrete, mortar and slate or to a cured polymer such as plastic (thermosetting or thermoplastic resin molded product) and rubber (tire, belt, hose, etc.), can be easily pulled out thereof like a melt-spun organic fiber having a circular section, and a manufacturing method of the cured article.
      SOLUTION: The manufacturing method of the cure article comprises: a crushing step of crushing twisted yarns comprising organic fibers to obtain crushed twisted yarns; a compounding step of compounding the crushed twisted yarns with an uncured material and; a curing step of curing the uncured material with which the crushed twisted yarns are compounded. The twisted yarns comprising organic fibers such as a polyamide, a polyester, polyvinyl alcohol and a polyolefin are crushed so that the fibers composing the twisted yarns achieve a shape in which the sectional shape changes in the lengthwise direction. The resultant fibers are mixed into or embedded in the cured article as reinforcing fibers.

    • 要解决的问题:为了提供一种固化物,其中可以通过复合有机纤维来高度抑制裂纹扩大,碎片掉落或过度变形,通过简单,低的粘度赋予与固化物具有优异物理粘合性的形状 即使是有机纤维,即使简单地添加到诸如水泥混凝土,砂浆和石板的水硬固化制品中,也可以添加到诸如塑料(热固性或热塑性树脂模制产品)和橡胶(轮胎 ,皮带,软管等),可以容易地被拉出,如具有圆形截面的熔纺有机纤维和固化制品的制造方法。 解决方案:固化制品的制造方法包括:破碎包含有机纤维的加捻纱线的破碎步骤以获得压碎的加捻纱线; 将经破碎的加捻纱与未固化的材料混合的复合步骤; 固化破碎的加捻纱与其混合的未固化材料的固化步骤。 包括有机纤维如聚酰胺,聚酯,聚乙烯醇和聚烯烃的加捻纱被压碎,使得构成加捻纱线的纤维实现截面形状在长度方向上变化的形状。 将所得纤维作为增强纤维混合或固化在固化物中。 版权所有(C)2009,JPO&INPIT
