一种仿啄木鸟头部的抗冲击结构及其制作方法

A woodpecker head-imitated impact-resistant structure and a manufacturing method therefor, relating to the field of impact-resistant structures and bionics. The impact-resistant structure comprises an outer housing (5), a damping layer (6), a cancellous bone vibration absorption layer (7), an inner housing (8), resin beads (9), and a cylindrical cover (12); double-layer lightweight housing design is adopted; an elastic damping material and a porous foam material are filled between the inner housing (8) and the outer housing (5); the resin beams (9) are filled between the metal inner housing (8) and a protected precise electronic component or device (10). The designed woodpecker head-imitated impact-resistant structure has the function of absorbing vibration and impact energy, thereby yielding an impact protection effect on a protected piece; furthermore, the structure is provided with the cylindrical cover (12), so that the structure has both sealed and unsealed states. The structure is simple in process and capable of achieving effective vibration and impact protection for the precise component or device (10)

Low-velocity impact damage localization of GF/epoxy laminates by the embedded MWCNT@GF sensor network

This paper presents the damage location technology in glass fiber reinforced epoxy (GF/epoxy) composite laminates subject to low-velocity impact. Multi-walled carbon nan-otube coated GF (MWCNT@GF) is designed and manufactured as the sensor. MWCNT@GF sensor is embedded into the laminates to form an in situ sensing network. Relative resis-tances of the sensors are recorded after the low-velocity impact test. An algorithm is compiled to deal with the relative resistance data and help showing the impact damage location on a contour map. Results show that the in situ monitoring method with embedded MWCNT@GF sensor could locate the impact damage with high accuracy. (C) 2020 The Authors. Published by Elsevier B.V.</p
