Abstract

Oblong composite bodies comprise (a) an oblong core of a skinned foam with a thin virtually non-cellular surface layer with a density of >=0.9 g/cm3, the core having a shear strength of >=15 kg/cm2 and an average density of 0.25-0.6 g/cm2, varying from 0.05-0.3 g/cm3 in the innermost part to at least twice this density in the outer part bordering on the skin, (b) >=1 seamless casing layer of woven glass fibre in contact with the polymer layer, and encapsulated in and chemically bonded to it by means of a silane adhesive and a thermosetting resin cured in situ, (c) >=1 oblong layer of unidirectionally laid continuous glass fibres oriented along the length of the core and bonded to the non woven glass fibre casing by a silane adhesive and a thermosetting resin layer cured in situ, and (d) an outer layer of a thermosetting resin cured in situ. Used esp. for the construction of glass fibre reinforced hockey sticks, canoe paddles, cricket bats, baseball bats, etc.
