    • Embodiments of the invention include a method by which particulate reinforcement is applied to dry fiber via a powder coating or a "dusting" process and subsequently infused with a resin before or after forming a lay-up. Upon curing a composite lay-up, the particulate reinforcement may be randomly distributed through the laminate composite, forming a wear surface on one side. The application of dried bulk particulate may be applied to a fibrous sheet (or fiber reinforcement) such that the coupling of the particulate reinforcement to the fiber includes a mechanical and/or electrostatic process. Agitating the particulate reinforcement prior to being applied to the dry fiber may induce an electrostatic charge. Further, the particulate reinforcement may include raw microspheres of different types and styles, such as organic, inorganic, unexpanded, pre-expanded, etc.
    • 本发明的实施方案包括通过粉末涂料或“除尘”方法将颗粒增强剂施加到干纤维上并随后在形成铺层之前或之后注入树脂的方法。 在固化复合层合物时,颗粒增强物可以随机分布穿过层压复合材料,在一侧形成磨损表面。 干燥的散装颗粒的施加可以施加到纤维片材(或纤维增强材料)上,使得颗粒增强物与纤维的耦合包括机械和/或静电过程。 在施加到干纤维之前搅拌颗粒增强物可能引起静电荷。 此外,颗粒增强材料可以包括不同类型和类型的原料微球,例如有机,无机,未膨胀,预膨胀等。

    • The present invention relates generally to bristles, in particular tooth-cleaning bristles comprising a surface structure with at least one surface recess such as dimples and pittings, and to a method for manufacturing such a bristle. Moreover, the present invention also relates to a toothbrush head including a plurality of tufts of such bristles. According to the present invention, the method for manufacturing the bristle is characterized in that a bristle body with at least a portion made of a material soluble by a corrosive agent is covered in part with a cover layer stable to said corrosive agent such that a surface portion of said bristle body substantially corresponding to said at least one surface recess is uncovered, and said bristle body is contacted with said corrosive agent for a limited time to create the surface recess in said uncovered surface portion. Correspondingly, a bristle according to the present invention is characterized in that its surface structure includes at least one etch pitting or etch recess in a bristle body made at least in part of a material soluble by a corrosive agent.
    • 本发明一般涉及刷毛,特别是包括具有至少一个表面凹陷(如凹坑和点蚀)的表面结构的牙齿清洁刷毛,以及用于制造这种刷毛的方法。 此外,本发明还涉及一种包括多个刷毛簇的牙刷头部。 根据本发明,用于制造刷毛的方法的特征在于,具有至少一部分由可溶解腐蚀剂的材料制成的刷毛的部分被覆有与所述腐蚀剂稳定的覆盖层,使得表面 基本上对应于所述至少一个表面凹部的所述刷毛体的部分未被覆盖,并且所述刷毛体与所述腐蚀剂接触有限的时间以在所述未覆盖的表面部分中形成表面凹部。 相应地,根据本发明的刷毛的特征在于其表面结构包括至少部分由腐蚀剂可溶解的材料制成的刷毛体中的至少一个蚀刻点蚀或蚀刻凹槽。
