Cure Shrinkage Behavior of Polymer Matrix Composite according to Degree of Cure

open access: yesComposites Research, 2014
ABSTRACT: Cure shrinkage during cure process of polymer matrix composites develope residual stress that causesome structural deformation, such as spring-in, spring-out and warpage. The carbon/epoxy prepreg used in this studyis Hexply M21EV/34%/UD268NFS/IMA-12K supplied by Hexcel corp.

Latent curing of epoxy-thiol thermosets [PDF]

open access: yes, 2017
Epoxy-thiol curing is a click reaction which allows quantitative yield of the end products. The base-catalyzed reaction is rapid at low temperatures so it is most often desirable to harness reactivity by using latent catalysts.

Cure kinetics of ring-opening metathesis polymerization of dicyclopentadiene [PDF]

open access: yes, 2002
The cure kinetics of polydicyclopentadiene (pDCPD) prepared by ring-opening metathesis polymerization with three different concentrations of Grubbs' catalyst was examined using differential scanning calirimetry (DSC).

When is a network epidemic hard to eliminate?

open access: yes, 2015
We consider the propagation of a contagion process (epidemic) on a network and study the problem of dynamically allocating a fixed curing budget to the nodes of the graph, at each time instant.
