Summary Process allows the combination of glass filled polypropylene and continuous long glass fiber weave to form a hybrid thermoplastic composite (HTPC). HTPC beam exhibits 39% less intrusion during 5 mph pole test, 35% less intrusion for 5mph barrier, and 76% increase in static load capacity. Also eliminates energy absorbing foam. Weight Savings: 42% lighter than a typical steel beam Cost Savings: 27% over the previous product. Cost Avoidance: N/A
Most Innovative Feature Process used to manufacture the beam allows the combination of glass filled polypropylene and continuous long glass fiber weave to form a hybrid thermoplastic composite (HTPC) material.
Other Innovative Features The HTPC beam bumper Impact performance, energy absorption and effiency, exceed all other plastic/composite beams in its class. It eliminates both the need of a metal beam and energy absorbing foam.
Forming Process Thermoforming of Twintex sheets (60% glass weave); Thermoplastic Injection Molding; Water jet cutting.
First time process used? Yes. Plastic Omnium has obtained four patents for this product, and has 3 more under review.
Previous Process Used This process is unique because injection molding or thermoforming alone could not yield such a product.
Tooling Innovations 6-Axis robots used to handle Twintex sheets, stack, preform and insert them into the mold prior to injection. Also, the beams are finished by additional 6-axis robots in a water jet cutting cell.
New Material Developments None.
Weight Savings Same as GMT bumper beam systems, 42% lighter than a typical steel beam bumper system.
Direct Cost Savings 27% cost savings over the previous product.
Direct Consumer Benefit Significant improvement of impact performance. The beam is able to withstand two consecutive 5mph flat barrier impacts without replacement. The HTPC beam exhibits 31% less intrusion during a 5mph pole test over the previous product.
Translates to other Vehicles? It can be utilized across all vehicle lines.
Safety Benefits Improved bumper performance that maintains structural integrity after an impact.
Environmental Benefits N/A
Additional Info This process can be applied to a wide range of structural parts offering cost effective, environmentally friendly, and mass efficient parts.
