Abstract A new material for the structure of honeycomb sandwiched XinBi board has been in active service. In this paper, structural defects are embedded easily damaged parts material, and ultrasonic method is used to detect parts, acoustic signals defect echo obtained, which provides a reference damage evaluation kind structures site detection.

A multi-panel PMC infilled system, using polymer matrix composite (PMC) material, was introduced as new conceptual design for seismic retrofitting. A proposed multi panel PMC infilled system was composed of two basic structural components: inner PMC sandwich infills and outer FRP damping panels. The PMC material had high stiffness-to-weight and strength-to-weight ratios. Therefore, the addition...

Structurally porous metal sandwich panels consisting of dense face sheets and porous cores of controlled relative density can be manufactured by trapping inert gas during hot isostatic pressing and modifying its distribution via subsequent thermomechanical forming. A plane-strain solution for analyzing the open-die forging of such a plastically compressible sandwich panel is developed. An effec...

Sandwich panel adalah kombinasi antara dua pelat kayu yang dipisahkan oleh bagian inti (core). Manfaat dari penggunaan spesimen ini masih belum maksimal hanya sebatas non struktual pada pembuatan kapal kayu. Tujuan penelitian untuk mengetahui karakteristik sandwich dengan metode casting dan hand layup. Hasil pengujian densitas memiliki nilai lebih baik 1,11 gram/cm³ sedangkan murni 1,21 gram/cm...
