Betafoam low-density acoustical foam from Dow Automotive helps manage road and chassis noise, vibration and harshness in the 2004 Cadillac SRX.
The higher-density structural foam provides stability and crash/energy management benefits to the A-pillar and longitudinal rails.
Betafoam, a two-part polyurethane foam, is typically injected into body cavities during vehicle assembly, where it cures almost immediately, providing an acoustical seal or near-immediate reinforcement of the vehicle’s body structure. For the Cadillac SRX, the Dow Automotive team provided application development, design, material expertise, product testing and evaluation at Dow Automotive's lab in Auburn Hills.
The material is now available in low-MDI formulations, thus relieving ventilation requirements in the assembly environment. Betafoam is available in several formulations including multiple grades of the new low-MDI material.
Designers at Elemental Motor have utilised tailored fibre placement (TPF) to extend the use of carbon composites in its RP1 sports car.
Australian organisations Austrak, Laing O’Rourke and the University of Southern Queensland (USQ) have joined forces to develop polymer composite solutions for bridge transoms in a $10 million project titled Polymer Composite Transoms for Rail Bridge Deck Replacement (CompTrans).
Porcher Industries and its US subsidiary BGF Industries will present their latest innovations at CAMX 2018 on 15-18 October in Dallas, Texas, US, including new dry fibres for aerospace and automotive applications, the STELIA thermoplastic fuselage demonstrator, and solutions for the industrial, construction and sports and leisure sectors.
