Article Preview

A scanning electron microscope (SEM) was used for the observation of the microstructures of a chafer cuticle. It showed that the cuticle is a kind of biocomposite consisting of complected chitin-fiber plies and sclerous protein matrix. The observation also showed that there are many holes in the cuticle and the complected fibers continuously reel these holes forming a kind of fiber-complected and reeled microstructure. Based on the SEM observation, a kind of biomimetic composite laminate with complected and reeled structure was fabricated with a special mould and process. The ultimate strength of the obtained biomimetic composite laminate was experimentally investigated and compared with that of the conventional drilling-hole composite laminate. It showed that the ultimate strength of the biomimetic composite laminate is markedly larger than that of the drilling-hole composite laminate.
