Summary: This article investigates the thermal responses of one-ply triaxially woven fabric composites (TWFCs). Temperature change experimental observations are conducted on plate and slender strip specimens of TWFCs. Computational simulations are performed to analyze the anisotropic thermal effects of the observed deformation and a new thermal deformation description called the coefficient of thermal twist is characterized for TWFCs.

Summary: In this study, PET fabric was treated with sodium lignin sulphonate (SLS), resulting in improved flame retardancy and thermal stability. The chemical loading and flame retardancy were positively correlated. The experimental results also demonstrated that SLS treatment effectively reduced the peak heat release rate and carbon monoxide liberation during combustion of PET fabric.

Summary: Topical cross-linking of UHMWPE fabric can enhance its resistance to tear and perforation, potentially increasing the protection provided by soft body armor. The cross-linking strengthens the fabric, particularly along its bias direction. Experiments show that even with just 1% cross-linker, the ballistic limit can be significantly increased by 18 m/s.

Summary: This study investigates the preparation of a polymer separator with enhanced thermal stability for lithium-ion battery separators. By coating a solution of acetyl cellulose and glycerin on polypropylene, the flexibility of the cellulose chains is improved and the formation of numerous pores is promoted. The thermal stability of the separator is further enhanced by coating a mixed solution twice and applying water pressure to partially connect the pores. The average water flux and decomposition temperature of the separators are significantly improved compared to pure acetyl cellulose, confirming the interaction with polypropylene.

Summary: This article investigates the impact of weave parameters on the drilling mechanism of composite materials. It is found that the drilling power and thrust force are directly proportional to the fabric stiffness. Delamination caused by drilling thrust is a common issue in drilled laminate composites. The development of a drilling index allows for evaluation of the impact of fabric design on composite drilling performance.
