The observation on conifer wood shows that wood is a kind of biocomposite consisting of wood fibers and lignin matrix. The wood fibers are embedded in the lignin matrix with parallel distribution. It is also observed that the wood fibers continuously envelop the columned branch cores in the wood forming a kind of enveloping-core fiber distribution (ECFD). The ultimate load of the composite model with the ECFD is investigated and compared with that of the composite model with non-enveloping-core fiber distribution (NECFD). It shows that the strength of the composite model with the ECFD is larger than that of the composite model with NECFD. A kind of mimetic-wood composite specimens with the ECFD is also fabricated. The test was carried out with ECFD specimens and compared with that of the composite specimens with the NECFD. The result show that the ultimate strength of the former is significantly larger than that of the latter.
