Comparison of Compressive Properties Between Va-cuum Infusion and Hand Lay-Up Method Toward Bal-sa Core Sandwich Composites

comparison of compressive properties between va-cuum infusion and hand lay-up method toward bal-sa core sandwich composites

the aim of this work is to evaluate the influence of fabrication methods on the com-pressive properties of sandwich composites using both experimental work and numerical simulations. two types of sandwich composites with e-glass/kevlar/polyester resin facings and end-grain balsa wood as core have been produced by vacuum infusion processing (vip) and hand-lay up (hl) method. compression tests on...

Blast Performance of Sandwich Composites with In-Plane Compressive Loading

An experimental investigation was conducted to evaluate the dynamic performance of E-glass Vinyl Ester composite face sheet / foam core sandwich panels when subjected to pre-compression and subsequent blast loading. The sandwich panels were subjected to 0 kN, 15 kN and 25 kN of in plane compression respectively, prior to transverse blast wave loading with peak incident pressure of 1 MPa and vel...

Data characterizing compressive properties of Al/Al2O3 syntactic foam core metal matrix sandwich

Microstructural observations and compressive property datasets of metal matrix syntactic foam core sandwich composite at quasi-static and high strain rate (HSR) conditions (525-845 s(-1)) are provided. The data supplied in this article includes sample preparation procedure prior to scanning electron and optical microscopy as well as the micrographs. The data used to construct the stress-strain ...

effect of rigid polyurethane foam core density on flexural and compressive properties of sandwich panels with glass/epoxy faces

sandwich panels as composite materials have two external walls of either metallic or polymer type. the space between these walls is filled by hard foam or other materials and the thickness of different layers is based on the final application of the panel. in the present work, the extent of variation in core density of polyether urethane foam and subsequent flexural and compressive changes in s...
