Carbon Fiber Reinforced Shape Memory Polymer Composites

Journal of Intelligent Materials Systems and Structures, 2000
In this paper we present results on the deformation of carbon fiber reinforced shape memory polymer matrix composites for deployable space structure applications. The composites were processed using resin transfer molding or a pre-impregnated (pre-preg) laminate press, with both satin and plain weave fiber architectures.

Numerical Relaxation Analysis of Carbon Fiber Reinforced Polymers

Macromolecular Symposia
AbstractCarbon fiber reinforced polymers are widely used to manufacture aerospace deployable structures. These structures are folded in launch configuration and then deployed in space for operational activities. Since the stowage of deployable structures in folded configuration occurs for long time, the understanding of the viscoelastic properties of ...

Effective Splices for a Carbon Fiber–Reinforced Polymer

Transportation Research Record: Journal of the Transportation Research Board, 2009
Carbon fiber–reinforced polymer (CFRP) materials have been used successfully to strengthen reinforced concrete bridges and structures. Recently, a new high modulus CFRP strengthening system was developed to increase the allowable load carrying capacity and to enhance the serviceability of steel bridges and structures.

Nanocomposites for Carbon Fiber-Reinforced Polymer Matrix Composites

46th AIAA/ASME/ASCE/AHS/ASC Structures, Structural Dynamics and Materials Conference, 2005
A high temperature damage tolerant epoxy resin system was modified with three types of nanoparticles: chemically modified montmorillonite (MMT) organoclays, surface treated nanosilica, and surface modified carbon nanofibers (CNF) to create new types of epoxy nanocomposites.

Development of smart hybrid carbon fiber reinforced polymers

SPIE Proceedings, 2007
In this paper, the development and application of smart hybrid carbon fiber reinforced polymers (HCFRPs) are summarized. The active elements of the HCFRPs are carbon fibers/tows in terms of their piezoresistivity and electrical conductivity. Generally, the HCFRPs are divided into two types: HCFRP composites and HCFRP sensors.
