This study investigates the impact behaviour and post-impact performance of polyamide-6 glass fibre reinforced composites, manufactured by thermoplastic resin transfer moulding. Impact test samples were extracted from quasi-isotropic laminates using two different sizings, both with a volume fraction approximately 52%. A previous showed that one these sizings enhanced interfacial strength Mode I...

The impact damage is the most destructive effect on FUM during drum screening. To explore of screening, a free-drop test device was built to simulate FUM. Adopting an L16(45) orthogonal experiment scheme, we investigated mass, dropping height, collision material, and number collisions bruise depth specific surface area bruise, peak force, Ratio amplitude attenuation. Then, analyzed influence th...

Impact experiments of thick fabric carbon/epoxy laminate specimens, with small thickness ratio, are conducted at distinct energy levels and thicknesses to characterise the damage process. These specimens loading conditions representative a new generation critical structural components in aviation, such as wing spars, landing gear beams fittings, that increasingly being made entirely from compos...

It has been reported that cavitation bubbles (air–liquid interface) by femtosecond laser and ultrasonic irradiations are effective for metastable phase crystallization in polymorph control. also noted generated mechanical shock when dropping a vial. Here we describe the of acetaminophen drop impact. In condition where spontaneous nucleation did not occur, impact produced form (form II) trihydra...

In order to study the impact of on sandstone, dynamic is conducted sandstone through drop hammer test, wave velocity test impacted specimen by using instrument, and damage effect analyzed calculation formula. The results show that greater velocity, smaller measured sandstone.

his paper introduces a test methodology to examine the urability of surface mount interconnects under impact oading when a portable electronic product is dropped. onventional testing approaches that consider the agnitude of loading (total impact energy, impact direction, nd number of impacts) as the governing criterion for amage accumulation, typically report difficulties in orrelating with imp...
