发明名称 | Method of providing through-thickness reinforcement of a laminated material | ||
摘要 | A laminated composite material comprising a polymeric matrix material and plurality of fiber layers is heated to a first pre-determined temperature which is defined as the temperature at which there is a first pre-determined time interval until the matrix material reaches its gel point. The first pre-determined time interval being defined as the time required to insert the required quantity of through-thickness reinforcement fibers into the laminated material. A plurality of holes is formed in the laminated material; each hole being formed by inserting a needle having a conical tip, into the laminated material. A reinforcing element is then inserted into each of a respective one of the plurality of holes. | ||

主权项 | 1. A method of providing through-thickness reinforcement of a laminated material, the laminated material comprising a polymeric matrix material having a gel point, the method comprising the steps of: (a) providing a laminated material; (b) heating the laminated material to a first pre-determined temperature, wherein the first pre-determined temperature is determined on the basis of the gel point of the polymeric matrix material, the first pre-determined temperature being less than a temperature at which the polymeric matrix material begins to cure; (c) forming a plurality of holes in the laminated material; and (d) inserting a reinforcing element into each of a respective one of the plurality of holes. | ||
