Stratifiés -- Propriétés mécaniquesIndex. décimale : 668.4 Plastiques, vinyles Résumé : Interfacially flocked Z-axis oriented reinforcing fibres can dramatically improve the interlaminar shear strength of organic polymer laminar composites (OPLC). To this end, three flock process methodologies were developed: "wet flocking", "dry flocking" and "pre-flocking". As the pre-flocking methodology was found to produce the composite panels with the highest interlaminar shear strength, it should be further developed as the most "user-friendly" way of introducing flocked fibre reinforcement technology into OPLC applications. Note de contenu : - Z-AXIS FLOCK FIBRE INTERLAMINAR REINFORCEMENT METHODOLOGY : Wet flocking - Dry flocking - Pre-flocked composite reinforcing layers
- EXPERIMENTAL MATERIALS AND LAMINATING PROCEDURES

Bruit -- Lutte contreIndex. décimale : 668.4 Plastiques, vinyles Résumé : Parts made of high-modulus, high-strength composite materials tend to be very noisy, in particular when (even small) shocks occur, and the sound generated by these parts can be uncomfortable and unpleasant. In air transport, acoustic comfort tends to become a major issue, bath for airline passengers and VIPs in business jets, even though aircraft trim panels and interiors are manufactured with glass fibre instead of carbon fibre. To address these issues, SMAC developed an innovative material based on the skin damping principle. Note de contenu : - Fig. 1. The skin damping principle
