POLYMER COMPOSITE COMPRISING AN INTERFACIALLY MODIFIED FIBER AND PARTICLE

摘要

Embodiments herein relate to a composite material including about 10 to 80 wt. % of a polymer phase, the polymer phase comprising a thermoplastic polymer with a density of less than about 1.9 g-m-2; and about 20 to 90 wt. % of a dispersed mixed particulate phase, the dispersed mixed particulate phase comprising a mixed particulate and about 0.005 to 8 wt. % of a coating of at least one interfacial modifier. The mixed particulate including a portion of a reinforcing fiber and a portion of a particle. The composite material having a Young's modulus of greater than 700 MPa. In various embodiments, structural building components made from the composite are included as well as additive manufacturing components made from the composite.
