摘要 |
<p>Laminate displaying improved blunt notch behaviour, so that it is suitable fore use as a constructional material in aviation and cosmonautics. It comprises at intermediate layer (3) of thermoplastic material reinforced by continuous glass filaments (4) having a modulus of elasticity of at l east 80 GPa. The glass filaments are composed of 58-69% b.w. of SIO2, 18-29% b.w. of AL2O3 and 7-19% b.w. of MGO. Preferably, they have a tenacity of at least 4 GPa, and an elongation at break of at least 4%. The thermoplastic material may be an amorphous resin having a Tg > 140 degrees C such as, e.g., polyarylates, poly(ether)sulfones, polyetherimides or poly-p-phenylene ethers, or a semi- or para-crystalline resin having a crystalline melting point > 170 degrees C, such as poly-phenylene sulfides, polyetherketones or liquid crystal polymers.</p> |
