This first part of a series papers on the thermo-mechanical responses fiber-reinforced composites at elevated temperatures reports experimental results required as input data in order to validate kinetic, heat transfer, and models being developed be discussed subsequent papers. Here techniques used for determination physical, thermal, mechanical properties their significance particular are discussed. The fire retardant system improve performance glass epoxy is combination cellulosic charring...
This article is part of a series on the thermo-mechanical responses fiber-reinforced composites at elevated temperatures and it follows first containing experimental results. A flame-retardant system consisting cellulosic charring agent an interactive intumescent additive (melamine phosphate) has been used in order to improve post-fire mechanical performance glass epoxy composites. The effect one-sided radiant heat residual flexural stiffness laminate coupons exposed incident fluxes 25 35 kW...
Abstract This work involves the development of novel glass fiber–reinforced composite materials containing a commercially available epoxy resin, phosphate‐based intumescent, and inherently flame‐retardant cellulosic (Visil, Sateri) phenol–formaldehyde (Kynol) fibers. The intumescent fiber components were added both as additives in pulverized form interdispersed with fabric scrim for partial replacement fiber. Thermal stability, char formation, flammability properties these structures studied...
Abstract The finite element method has been used to investigate the crashworthiness of regular conventional and re-entrant cellular foams in pristine defect forms. Defects were introduced by randomly deleting vertical ribs (cell walls), diagonal vertical-plus-diagonal from honeycomb models, which with suitable boundary conditions approximated three-dimensional foams. Generally, calculations show that leads a reduction magnitude Young's moduli Poisson's ratios, although there are some notable...
This work is concerned with physical testing of carbon fibrous laminated composite panels low velocity drop-weight impacts from flat and round nose impactors. Eight, sixteen, twenty-four ply were considered. Non-destructive damage inspections tested specimens conducted to approximate impact-induced damage. Recorded data correlated load–time, load–deflection, energy–time history plots interpret impact induced Data filtering techniques also applied the noisy that unavoidably generate due...
The thermal barrier efficiency of two types ceramic particle, glass flakes and aluminum titanate, dispersed on the surface carbon-fiber epoxy composites, has been evaluated using a cone calorimeter at 35 50 kW/m2, in addition to temperature gradients through samples’ thicknesses, measured by inserting thermocouples exposed back surfaces during tests. Two techniques dispersing particles have employed, one where were semi-cured laminate other their dispersion phenolic resin was applied...
Elastomers are used in numerous engineering applications such as sealing components, it is therefore important to devise a method that can accurately predict elastomers' response load. Many employ the use of these materials subject them nonlinear large strain; simple Hooke's law not sufficient describe their material behaviour. This paper presents an approach obtain properties elastomer under compression loading, based on hyperelastic strain formulation, through experimental test and finite...
