A bifunctional reagent containing a diazirine carbene precursor and benzyl bromide electrophile can be used to photofunctionalize Kevlar other inert polymers, providing sites for covalent attachment of dyes.

The term 'aramid fibre' refers to a manufactured fibre in which the fibre-forming substance is a long-chain synthetic polyamide with at least 85% of the amide linkages attached directly to two aromatic rings (Preston, 1978; Yang, 1993). 'para-Aramid fibres' are those in which the amide Iinkages are in the para (l,4) positions on the aromatic rings. para-Aramid fibres of poly(para-phenyleneterep...

The penetration behavior of Kevlar fabric intercalated with dry particles and shear thickening fluids (STF), highly concentrated fluid-particle suspensions, is presented. In particular, the role of particle hardness is explored by comparing fabric treatments containing SiO(2) particles, which are significantly harder than Kevlar, to treatments containing softer poly(methyl methacrylate) (PMMA) ...

In this paper, the behavior of high-velocity impact Kevlar fabric and elastomer composites was investigated both experimentally numerically. The experimental tests were performed by a gas gun device hemispherical projectiles at different velocities, ranging from 122 m/s to 152 for 2- 4-layer samples. penetration resistance these during determined using ABAQUS/Explicit. present study's novelty l...

Abstract In recent years, Arenga Pinnata fibre has been found with great potential to be used as reinforcement in material matrix composites. This study investigates the effect of contents toward manufacturing defects and interfacial adhesion reinforced Fiberglass/Kevlar hybrid composite boat construction. The testing coupons were prepared based on volume fraction which are 30%, 45%, 60%, 75%. ...
