Despite vigorous public education campaigns, funded screening programs, and multiple national / international practice guidelines [ 3, 4], 30 to 40%% of women do not take advantage of this low cost, high impact test [ 5].
Additionally, a control group wall panel design that was manufactured using a conventional carbon fiber reinforced polymer (CFRP), or more precisely a carbon fiber reinforced epoxy, indisputably failed two debris missile high-impact tests.
The aim of this study was to determine the role that frame and lens design play in lens retention during high-impact testing of safety eyewear that advertises conformance to the performance-based ANSI Z87.1-2003 standard.
For both sandwich structures numerical analysis reproduces physical behaviour observed experimentally in high velocity impact tests.
In the present study, high velocity impact tests were carried out on stainless steel/rubber/composite hybrid plates.
This research further investigates the dynamic compressive properties of spiral fibre reinforced concrete (SFRC) by conducting high rate impact tests using split Hopkinson pressure bar (SHPB).
High energy impact tests with projectile velocity ranging from 490 to 950 m/s were performed on both nano-reinforced epoxy-Kevlar 29 panels and epoxy-Kevlar 29 ones.
This particular design is characterized by its simplicity, excellent performance at low cost and compact dimensions, when compared to commercial systems, presenting an affordable option for materials characterization for high velocity impact tests.
In the current paper, a series of high velocity impact tests using ϕ50 and ϕ25 mm ice spheres and 0.32 g granite stones on non-crimp fabric (NCF) composite plates are reported.
The response to high velocity impact tests is assessed through the evaluation of the impact and residual velocities of the projectile and the ballistic limit, calculated using experimental data, is compared with the results given by an analytical model, showing a good agreement.
