This paper presents the results of an investigation effects hygrothermal conditioning on mechanical properties and fatigue behaviour epoxy-based composites reinforced with carbon, glass aromatic polyamide fibres. Cross-plied (0°/90°) laminates these materials, nominal fibre volume fraction ca . 0.6, were conditioned by drying, exposing to a 65% r. h. (relative humidity) atmosphere boiling in water. The treatments tensile shear strengths response when tested orthogonally at ±45° lay-up are...
Following an earlier comparative investigation of the tensile fatigue response, in terms stress versus log life curves, three epoxy-resin-based laminates 0/90 lay-up and reinforced with carbon, glass Kevlar-49 fibres, authors now present a study accumulation damage residual strengths fatigued laminates. A stress-independent parametric relationship between normalized number cycles is found to describe behaviour all composites, suggesting single major mode despite widely different mechanical...
The behaviour of polyester resin reinforced with hard-drawn steel wires and fully-softened the same has been studied in compression tests on free-standing cylinders which are parallel direction applied load. Despite predictions various theories compressive strength composites, two materials behave dissimilarly, their strengths fall well below values predicted by models based treatments fibres as col umns an elastic foundation. Fibres appear to buckle into helical shapes rather than planar...
Acoustic emission detection has been used to study the damage occurring in unidirectional carbon-fibre-reinforced plastics (CFRP) during cyclic loading and stress relaxation at high levels. The results suggest that true fatigue processes do not occur CFRP sustained cycling is of same kind as which occurs ordinary tensile loading. As a result either many reversals load or holding sample constant load, rate waves associated with fibre fractures diminishes time until becomes silent. A this...
BACKGROUND Given the high mortality and morbidity of emergency general surgery (EGS), designing implementing effective quality assessment tools is imperative. Currently accepted EGS risk scores are limited by need for manual extraction, which time-intensive costly. We developed an automated institutional electronic health record (EHR)–linked registry that calculates a modified Emergency Surgery Score (mESS) Predictive OpTimal Trees in Risk (POTTER) score demonstrated their use benchmarking...
A detailed analysis has been carried out of the strength and fatigue behaviour under constant–stress cycling four modern aerospace CFRP laminates, all having common lay–up [(±45,02)2]s. Despite some important differences in their basic material characteristics, responses materials were similar. This pattern resulted development a descriptive model constant–life which then used as basis for life–prediction procedure. Preliminary attempts at validation method have met with reasonable degree...
