In this work, the influence of surface roughness (<em>Ra</em>) of porous carbon derived from Metal-Organic-Frameworks (MOFs) with different shapes on impedance matching and effective absorption bandwidth (EAB) has been given special attention. The rod shaped, spherical and sheet-like porous carbon materials are obtained at 700 °C from Ni-BTC, Ni-DOBDC and Ni-BPDC. The Ni-DOBDC-700 spherical porous carbon with a relatively large <em>Ra</em> (290 nm) exhibits excellent absorption performance. The minmium reflection loss (<em>RL</em><sub><em>min</em></sub>) is −20.8 dB at 14 GHz and the EAB can reach at 6.7 GHz (11.1–17.8 GHz) when the thickness is 2.2 mm, which covers the Ku band. The spherical porous carbon, the Ni alloys and NiO particles serves the conduction channel, the sources of magnetic loss and interface polarization, respectively. The radar cross section (RCS) value of Ni-DOBDC-700 is less than −10 dB m<sup>2</sup> within the range of −60°–60° and the maximum scattering intensity is only −16.5 dB m<sup>2</sup> at the thickness of 2 mm.

Delamination and crack propagation are common structural issues that make regular inspection necessary in the composites. This study presents a structural health monitoring approach using a novel thermoplastic sensor for damage assessment in UD glass fibre epoxy composite. The thermoplastic sensor, composed of thermoplastic Elium and carbon nanotube materials, was prepared using the material extrusion filament technique. The electrical resistance of the filament was assessed under cyclic loading. The prepared material in the filament shape was embedded in the intermediate layer of UD glass fibre-epoxy composite. To evaluate damage propagation, flexural and electrical tests were carried out on the prepared smart composite laminate simultaneously. Three point flexural bending test was conducted for mechanical test and relative resistance change was recorded using a Wheatstone bridge circuit. Sharpe increase in the electrical output indicated that the smart composite is sensitive to damage extension under flexural load.

A numerically controlled angular solution blow spinning technique was developed to fabricate the micro-mesh with controllable gradient modulus properties. Using the micro-mesh as the backbone, tissue adhesive composite of two-dimensional anisotropic gradient modulus properties (2D A-GmTAC) could be conveniently prepared. Through systematic investigation and simulation, 2D A-GmTAC can effectively prevent wound tear and minimize stress concentration on tissue with tissue with anisotropic elastic modulus, demonstrating superior performance over its counterpart with isotropic elastic modulus properties.

A combination of fiber Bragg grating (FBG) and thermocouple sensors is employed to monitor temperature and strain data of the laminates during the curing process. On this basis, the effect of curing pressure on strain change at different process stages is investigated, and the forming quality is predicted online by the states of strain change at each stage. The external forming precision and internal microscopic defects of the samples are used to verify the predicted results. Results show that the strain change is mainly divided into heating, holding and cooling stages. In the heating/holding stage, the overall strain tends to increase, while in the cooling stage, the strain decreases and is accompanied by a jump phenomenon. The effect of curing pressure on the strain change is obvious. The higher the curing pressure, the better the bonding quality between fibers and resin, and the more significant the inhibition of strain changes by fibers. In order to obtain the good forming quality, the curing pressure should not be lower than 0.4 MPa. When the curing pressure is above 0.4 MPa, the thickness deviation of the laminate is limited to ±0.06 mm.
