Surf fin including injection molded pre-impregnated composite fiber matrix inserts

摘要

A fin for a water sports board including leading and trailing edges, and a base extending therebetween along a longitudinal base axis. A fin axis extends generally perpendicular to the longitudinal base axis, both axes residing within a longitudinal plane. First and second opposed side faces are formed on generally opposed sides of the longitudinal plane. First and second insert pre-preg sheets formed of structural strands bonded by a resin material are disposed adjacent respective ones of the first and second side faces on generally opposed sides of the longitudinal plane. An injection molded resin material is disposed between the first and second insert pre-preg sheets. A core is positioned between the first and second insert pre-preg sheets and is of a density less than the injection molded resin material.

1. A fin for a water sports board comprising:
a leading edge and a trailing edge; a base attachable to the water sports board and extending between the leading edge and the trailing edge, an interior central plane extending from the base and intersecting the leading edge and the trailing edge; a first side face and a generally opposing second side face, the first side face and second side face being formed on generally opposed sides of the interior central plane; a first insert pre-preg sheet disposed adjacent the first side face, the first insert pre-preg sheet including a plurality of first structural strands bonded by a first resin material; and an injection molded resin material adjacent and along the first insert pre-preg sheet, the injection molded resin material being different in material composition from that of the first resin material.
