چکیده

applications of thermoplastic composites have developed extensively. the thermoplastic composites in comparison with the thermoset composites have many advantages. thermoplastic composites can be melted and remolded many times. the duration of manufacturing process of these composites is short, producing very tough material, and the welding ability and multiple recyclings are their further advantages. the lack of knowledge in this group of composites is the main obstacle in their development. in this review the research works in the field of residual stresses in thermoplastic composites is presented. first, a literature survey on the available research on residual stresses on thermoplastics and thermoplastic composites reinforced with short fibers is compiled. moreover a review on the available research on residual stresses on thermoplastic composites reinforced with long fibers is presented as well. the effects of the residual stresses on these composites are discussed. experimental techniques for the measurement of residual stresses in thermoplastic composites and the methods for reducing the existing residual stresses are studied.

A Novel Method to Decrease Micro-residual Stresses of Fibrous Composites by Adding Carbon Nanotube

In this research, a novel method to decrease micro-residual stresses of fibrous composites by adding carbon nanotubes (CNTs) is proposed in detail. The negative coefficient of thermal expansion and the high young’s modulus of CNTs can be utilized to counterbalance the process induced residual stresses in composites. To this end, first, the effects of adding CNTs to the matrix of fibrous composi...

Residual Stresses in Tungsten / Bulk Metallic Glass Composites

Bulk metallic glasses (BMGs) have recently gained popularity due to the development of new alloys that yield a glassy structure even with “conventional” metal processing such as casting. The unique properties of BMGs potentially place them among significant engineering materials: very high strength (1.9 GPa) and fracture toughness (40-55 MPa.m), a near theoretical specific strength, excellent w...

Fracture Mechanics of Composites with Residual Thermal Stresses

The problem of calculating the energy release rate for crack growth in an arbitrary composite in the presence of residual stresses is considered. First, a general expression is given for arbitrary, mixed traction and displacement boundary conditions. This general result is then applied to a series of specific problems including statistically homogeneous composites under traction or displacement...

Application of Pulse Method to Incremental Slitting Measurement of Residual Stresses in Laminated Composites

In this research, the incremental slitting method was employed to determine throughthickness residual stress profile of a carbon/epoxy laminate. The method involves measuring strains at the back surface of the stressed specimen, while a narrow slit is cut by a CNC milling machine progressively from the top surface of the specimen. "Pulse Method" was selected as the computational approach for th...

Challenges in Biomass–Thermoplastic Composites

Wood and other biomass resources have been blended with thermoplastic such as polyethylene, polypropylene, polylactic acid and polyvinyl chloride to form wood plastic composites (WPC). WPCs have seen a large growth in the United States in recent years mainly in the residential decking market with the removal of CCA treated wood decking from residential markets. While there are many successes to...
