  • Patent number: 11499020
    Abstract: In order to solve problems of strength and volume of part, the invention provides an article reinforced by multi-dimensional fibers and a method for manufacturing the article. The article includes a core portion and a shell layer portion. The core portion is made of thermoplastic resin and the fibers in which a majority of and a minority of the fibers are respectively arranged in a major and a minor directions. The method includes: preparing a core portion made of thermoplastic resin and the fibers in which a majority of and a minority of the fibers are respectively arranged in a major and a minor directions, loading the core portion into a mold, and forming a shell layer portion in the mold to enclose the core portion. The article manufactured by the method of this invention can reduce the weight and increase the strength of the parts.

  • Patent number: 11254069
    Abstract: A composite material body (10) includes a first material layer (20) and a second material layer (30) overlapping the first material layer (20). The first material layer (20) and the second material layer (30) are wound to form a flexible and circular rod. Impact absorption is effectively improved and impact resisting strength is enhanced because energy-absorber or damping material or its composition is attached into the composite material body (10). Technical characteristics, effects and objects of this invention are achieved thereby.
