Abstract
A hybrid composite comprising a thermoplastic or thermoset matrix in which brittle and ductile fibers are present, wherein the fibers are configured such that the ductile fibers of the hybrid composite dissipate energy at a impact or overload by plastic deformation of the ductile fibers and show residual properties after impact or overload.
Claims19
A hybrid composite, the hybrid composite comprising:
- a thermoplastic or thermoset matrix in which brittle fibers and ductile fibers are present,
- wherein the ductile fibers are present individually or contained in a yarn having a twisting angle of less than 5° or being untwisted, each of the brittle fibers and the ductile fibers individually having a stiffness greater than 150 GPa, the ductile fibers having an elongation at break larger than 5%,
- the fibers being configured such that the ductile fibers of the hybrid composite on impact or overload dissipate energy by plastic deformation of the ductile fibers and the hybrid composite retains integrity after impact or overload,
- wherein the brittle fibers are carbon fibers and the ductile fibers are steel fibers.
