Abstract
A ratchet wrench includes a body formed entirely of glass-fiber-reinforced plastic material with a gear insert molded therein and a ratchet mechanism mounted on the insert and retained in place by retaining rings. The body includes layers of random discontinuous glass-fiber-reinforced plastic material and a band of unidirectional continuous glass-fiber-reinforced plastic material which are subjected to compression molding around the insert to form a composite wrench structure. Several insert configurations are disclosed.
