摘要: Abstract The effect of filler shape, volume fraction and high temperature cycle on the dynamic compression behavior rigid particle filled polymer composite is demonstrated by performing experiments using split-Hopkinson pressure bar (SHPB) setup. Two glass variants, spherical particles milled fibers, are reinforced into epoxy matrix upto 10% fraction. sets test specimens prepared; room cured (RTC) exposed (HTE) - ones prepared subjecting RTC composites to a beyond their transition (Tg). yield stress fiber which consistently higher in HTE cases increases with increasing whereas it remains nearly constant all composites. While materials exhibit strain softening characteristics, post-yield hardening attributed increased cross-link density matrix. Debonded fillers foot-prints crushed surfaces indicate relaxation residual stresses, developed at filler/matrix interface during curing process. Computational analyses suggest that average unaffected shape inclusions comparatively inclusion stresses slender provide better resistance deformation when compared circular ones. Near low fractions large inter-particle separation. results complement experimental observations where exhibited counterparts.
