Hybrid bridge design employs composite beams
The Texas Dept. of Transportation (TxDOT) recently installed over a drainage ditch in Refugio County a new bridge that incorporates composite beams, replacing a single-span, steel girder bridge. Located 35 miles from Corpus Christi, the 50-ft/15.4m long, 32-ft/10m wide bridge is the state’s second to use

Engineering Insights: Pedestrian Bridge Makes Case for Composites
Infusion molded deck incorporates high-performance core, which facilitates fast processing.
Read MoreResin matrices: Thermosets
Unsaturated polyester resins are the most widely used in commercial, mass-production applications, thanks to their ease of handling, good balance of mechanical, electrical and chemical properties and relatively low cost. Typically coupled with glass fiber reinforcements, polyesters adapt well to a range of fabrication
Read MoreRepair considerations
As more composite materials find a place on aircraft, boats, bridges and hundreds of other applications where part replacement is difficult and expensive, OEM engineers are considering the repairability of structural and secondary composite components during the initial design phase. According to a recent report by
