PCT No. PCT/FR92/00642 Sec. 371 Date Jan. 7, 1994 Sec. 102(e) Date Jan. 7, 1994 PCT Filed Jul. 6, 1992 PCT Pub. No. WO93/01372 PCT Pub. Date Jan. 21, 1993These transparent members, capable of withstanding mechanical stresses, comprise at least one glass member (A1) of stem, reed, tube, strip or sheet type and/or glass members (A2) of bead, particle or fragment type, transparent fibers (B) and a cured transparent resin (C) in which the fibers (B) and the members (A2) are embedded; the fibers (B) and the resin (C) with which they are coated being bonded to the members (A1), the resin (C) being chosen so as to exhibit, in the cured state, a refractive index which does not differ, at a wavelength of 510-520 nm, by more than 0.001 from that of the fibers (B) and from that of the members (A1) and (A2), it being nevertheless possible for the difference in index between the resin (C) and the members (A1) of strip or sheet type to range up to 0.01 when these members are large in dimension in relation to the overall structural member. It is thus possible to manufacture elongate members of pillar type (view in section below), of sheet, planar or curved type, and objects of more complex shapes.
