Numerical modelling is used to perform process simulations for thick-section composite laminates. Three forms of laminate are illustrate how thermal and cure gradients can be reduced by choice cycle. Low exotherm epoxy powders with the vacuum bag have shown success in both glass carbon fiber systems results presented present work show optimum cycle determined. The three geometries investigated ...
ABSTRACT Reported herein is an overview of the research being conducted within the Materials Division at NASA Langley Research Center on the development of smart material technologies for advanced airframe systems. The research is a part of the Aircraft Morphing Program which is a new six-year research program to develop smart components for self-adaptive airframe systems. The fundamental areas...
AIM To investigate the impact of histology on outcome in advanced oesophageal cancer treated with first-line fluoropyrimidine-based chemotherapy. METHODS Individual patient data were pooled from three randomised phase III trials of fluoropyrimidine-based chemotherapy ± platinum/anthracycline in patients with advanced, untreated gastroesophageal adenocarcinoma or squamous cell carcinoma (SCC) ...
Composite Technology Development Inc. (CTD) is currently funded through the NASA Advanced Component Technology (ACT) program to develop an off-set fed, TEMBO continuous composite surface deployable reflector for earth science applications. This type of reflector will offer a parabolic surface with the accuracy needed for RF science measurements to Ka band and beyond, including a clean aperture ...
