Mechanical Behaviour of Vacuum‐Infused GFRP Composites at Elevated Temperatures—Influence of Fibre Architecture

Fire and Materials, EarlyView.
ABSTRACT This study addresses the influence of fibre architecture on the mechanical properties of vacuum‐infused glass fibre reinforced polymer (GFRP) composites at elevated temperatures (ET). Laminates with three different fibre configurations—unidirectional (UD), bidirectional 0°/90° cross‐ply (BD), and ±45° off‐axis angle‐ply (OA) – were tested in ...

Charring Behaviour of Mass Timber: A Comparison of Thin Intumescent Coatings and Plasterboard

Fire and Materials, EarlyView.
ABSTRACT This study compares the charring behaviour of mass timber under varied heating conditions when protected by either different thin intumescent coating types or fire‐rated plasterboard layers. Bench‐scale fire experiments were conducted using the Heat‐Transfer Rate Inducing System (H‐TRIS).

A COMPARISON OF CNC LATHE MACHINE PROGRAMMING SIMULATION AND CNC LATHE MACHINE PRODUCTION RESULTS

Jurnal Dinamika Vokasional Teknik Mesin
This study compares the simulation results of a CNC lathe program with the actual production results of a CNC lathe. CNC lathes are used in the manufacturing of precision components for various industrial applications. Simulation of CNC lathe programs can provide an accurate estimate of the production output before the actual production process begins.
