Abstract
Provided is a porous structure, made from fiber-reinforced resin, which is lightweight and has excellent mechanical properties. The fiber-reinforced resin comprises a reinforcing fiber base material and a thermoplastic resin, wherein the reinforcing fiber base material includes 50-100 weight % reinforcing fibers having a fiber length of 2-10 mm, the total amount of reinforcing fibers being 100 weight %, and the thermoplastic resin has a long chain branched structure.
Claims15
A fiber reinforced resin comprising a reinforcing fiber base material and a thermoplastic resin, wherein
- reinforcing fibers having fiber lengths of 2 mm or more and 10 mm or less account for 50 or more and 100 or less wt % of the total weight, which accounts for 100 wt %, of the reinforcing fibers present in the reinforcing fiber base material,
- the thermoplastic resin has long chain branched structures, and
- the reinforcing fiber base material has a three-dimensional network structure formed of the reinforcing fibers.
