Datasets usually provide raw data for analysis. This raw data often comes in spreadsheet form, but can be any collection of data, on which analysis can be performed.
This article aims to develop a new type of sandwich composite with sewing 3D fabrics structure. The sandwich composite was a lightweight composite with reasonable mechanical properties and was manufactured by compression molding. The sewing 3D fabrics were produced by sewing jute yarns having configurable structures using Kevlar fiber threads. The composites had been subjected to compression, flexural and impact tests and their fracture surfaces had been characterized by scanning electron microscopy. The compression and impact properties of the blank composites and the sandwich composites were compared. In terms of flexural performance, three types of flexural failure modes were analyzed.
