Scots Pine Bark Extracts as Co-Hardeners of Epoxy Resins

open access: yesMolecules
Extracts from natural waste like bark or leaves are great sources of phytochemicals, which contain functional groups (hydroxyl, carboxylic, vinyl, allyl) attractive in terms of polymer synthesis.

Electron and proton absorption calculations for a graphite/epoxy composite model [PDF]

open access: yes
The Bethe-Bloch stopping power relations for inelastic collisions were used to determine the absorption of electron and proton energy in cured neat epoxy resin and the absorption of electron energy in a graphite/epoxy composite.

Development of a heterogeneous laminating resin system [PDF]

open access: yes
The factors which effect the impact resistance of laminating resin systems and yet retain equivalent performance with the conventional 450 K curing epoxy matrix systems in other areas were studied.

Thermochemical tests on resins: Char resistance of selected phenolic cured epoxides [PDF]

open access: yes
Curing epoxy resins with novalac phenolic resins is a feasible approach for increasing intact char of the resin system. Char yields above 40% at 700 C were achieved with epoxy novalac (DEN 438)/novalac phenolic (BRWE 5833) resin systems with or without ...

Dynamic stress analysis of smooth and notched fiber composite flexural specimens [PDF]

open access: yes
A detailed analysis of the dynamic stress field in smooth and notched fiber composite (Charpy-type) specimens is reported in this paper. The analysis is performed with the aid of the direct transient response analysis solution sequence of MSC/NASTRAN ...

Effects of high energy radiation on the mechanical properties of epoxy/graphite fiber reinforced composites [PDF]

open access: yes
Publications and theses generated on composite research are listed. Surface energy changes of an epoxy based on tetraglycidyl diaminodiphenyl methane (TGDDM)/diaminodiphenyl sulfone (DDS), T-300 graphite fiber and T-300/5208 (graphite fiber/epoxy ...
