Glass fibres which are distinguished by their greatly reduced carcinogenicity have an average fibre diameter of &lt;8 .mu.m, preferably &lt;3 .mu.m, with more than 10% of the fibres having a diameter of &lt;3 .mu.m. The types of glass used for producing these fibres are characterized by containing the following compounds in the proportions shown in mol %:

Glass fibres with improved biological compatibility

Sandwich laminates capable of withstanding high stresses, especially skis, can be manufactured by covering the wall of a mold cavity with a wet laminate, laying extremely fine glass fiber paper thereon and after closure of the mold introducing into the mold cavity a reaction mixture forming a rigid foamed plastic, which cures to a rigid foam core.

Process for the manufacture of a sandwich laminate and the resultant

The invention relates to fibre or filament mixtures consisting of high shrinkage side-by-side bifilar (mod)acrylic fibres or filaments separately containing TiO.sub.2 and carbon black and of normal fibres or filaments of polyamide, polyester, polyalkylene, poly(mod)acrylic, wool or cotton.

Fibre and filament mixtures containing high-shrinkage bifilar

The invention relates to novel permanently antistatic polyamide compositions comprising an aliphatic polyamide and from 0.5 to 40 % by weight, based on the polyamide composition, of a polyalkylene oxide obtained by the copolymerisation of mono-epoxides with di- or tri-epoxides.
