Method and apparatus for producing a reinforcement mesh
A method and an apparatus for producing a reinforcement mesh. Here, a reinforcement fiber strand is firstly saturated with a resin (H) and cured to form a cured, fiber-reinforced strand material. The strand material present as an endless material is then cut lengthwise into bars, which are then used as longitudinal bars or transverse bars for forming the reinforcement mesh. A connecting material is used at each intersection point between a longitudinal bar and a transverse bar and is dispensed in liquid form at the intersection point or is liquefied and then cured at the intersection point. A fixed connection is thus created between the longitudinal bars and the transverse bars at the intersection points. Between the intersection points, the longitudinal bars and the transverse bars have portions that are free of connecting material.
COMPRESSION-MOLDED FIBER-COMPOSITE PARTS AND METHODS OF FABRICATION
Fiber-reinforced composite parts include select portions containing a plurality of co-aligned fiber. The parts are fabricated by placing substantially preforms into a mold cavity to form a layup, and compression molding the layup to consolidate the preforms to provide a fiber-reinforced composite part. Different sections of the part can be derived from preforms having different shapes and different compositions.
