Abstract
A utility pole includes a thermoplastic composite material including: (a) at least one olefin polymer; and (b) at least one reinforcing fiber material embedded in the at least one olefin polymer, the thermoplastic composite material having a specific tensile strength higher than or equal to 15 MPa/(gr/cm3), preferably 20 MPa/(gr/cm3) to 200 MPa/(gr/cm3), and more preferably 30 MPa/(gr/cm3) to 150 MPa/(gr/cm3) and a specific tensile modulus higher than or equal to 2000 MPa/(gr/cm3), preferably 2500 MPa/(gr/cm3) to 20000 MPa/(gr/cm3), and more preferably 3000 MPa/(gr/cm3) to 15000 MPa/(gr/cm3).
