Abstract (en)
[origin: US4700647A] Boom of the wishbone-type for sailing boards, where the spars (4,6) at least have a core (12) made from a rigid foam, which has essentially plane surfaces on the inside and outside of the spars, which extend across a significant section of the length of the core. On the plane surfaces there are arranged synthetic-resin-strengthened UD-slivers (22), which extend in the longitudinal direction of the spars across the length thereof, and there is provided an outer layer (24) from a synthetic-resin-strengthened fibre fabric or braiding with slivers intersecting at an angle of between 30 DEG and 60 DEG to the longitudinal extension of the spars. The UD-slivers (22) are preferably arranged between the inner and the outer fabric layer (20,24) in the form of previously cured CFK-UD-strips.
