Autor: Liwei Wen, Shihao Li, Zhentao Dong, Haiqing Shen, Entao Xu

Publikováno v: Applied Sciences, Vol 14, Iss 13, p 5657 (2024)

Due to the black and glossy appearance of the carbon fiber prepreg bundle surface, the accurate identification of surface defects in automated fiber placement (AFP) presents a high level of difficulty. Currently, the enhanced YOLOv7 algorithm demonst

Use of calcium silicate-coated paraffin/expanded perlite materials to improve the thermal performance of cement mortar

Autor: Yingzi Yang, Hongwei Deng, Entao Xu, Mingjun Xie, Yushi Liu, Xiaojian Gao

Publikováno v: Construction and Building Materials. 189:218-226

Here we demonstrate thermal energy storage cement mortar (TESC) developed by integrating cement mortar with a calcium silicate-coated paraffin/expanded perlite based form-stable phase change material (CPEP). The thermophysical properties, microstruct
