EXCIMER LASER ABLATION OF GLASS FIBER IN REINFORCED POLYMER

Materials and Manufacturing Processes, 2002
In excimer laser ablation of glass fiber reinforced polymer, the fibers were found to be acting as refocusing lenses and caused partial fiber removal within the fiber. An analytical analysis based on Snell's law of refraction was used to calculate the laser intensity within the fiber, and the results of which were able to explain the partial removal ...

Shock response of a glass-fiber-reinforced polymer composite

Composite Structures, 2003
Abstract The present work describes the compression and release response of a glass-fiber-reinforced polyester composite (GRP) under shock loading to 20 GPa. Shock experiments in GRP were performed at Sandia National Laboratories and the US Army Research Laboratory. GRP is a heterogeneous material.

Direct Observation of Interfaces between Glass Fibers and Polymers in Glass Fiber Reinforced Plastics

1990
The interface between glass fibers, which coated with a binder system and matrix polymer in glass fiber reinforced plastics is investigated by means of scanning electron microscope (SEM) and transmission electron microscope (TEM) using new method for making ultra thin specimens.

Tensile behavior of glass fiber‐reinforced acetal polymer

Journal of Applied Polymer Science, 1969
AbstractThe tensile stress‐strain behavior of glass fiber‐reinforced polyacetal resin was investigated for various fiber concentrations, fiber length distributions, and finishing agents. The polyacetal fiber blends change considerably in strength and elongation at break when treated with ammonium chloride, but otherwise similar specimens still follow a

Effects of moisture on glass fiber-reinforced polymer composites

Journal of Composite Materials, 2014
Glass fiber polymer composites are used in wind turbine blades because of their high-specific strength and stiffness, good fatigue properties, and low cost. The wind industry is moving offshore to satisfy economies of scale with larger turbines. High humidity in this environment degrades mechanical performance of wind turbine blades over their lifetime.

Performance of Hollow Glass Fiber-Reinforced Polymer Rebars

Journal of Composites for Construction, 1999
The results of bond and tensile strength investigation of hollow glass-fiber reinforced plastic rebars are presented. Rebars with similar geometries but different microstructures were evaluated. Bond characteristics of on- and off-axis specimens, in terms of maximum sustained load, bond strength and stress, concrete compressive strength, and initial ...

One-Way Slabs Reinforced with Glass Fiber Reinforced Polymer Reinforcing Bars

SP-188: 4th Intl Symposium - Fiber Reinforced Polymer Reinforcement for Reinforced Concrete Structures, 1999
Twelve reinforced concrete deck panels were tested to study the potential of glass fiber reinforced polymer (GFRP) rebars as a replacement for epoxy coated steel (ECS) rebars in concrete bridge decks. Span lengths during testing were 2130 mm and 2740 mm.

Fracture toughness of glass fiber‐reinforced acetal polymer

Journal of Applied Polymer Science, 1971
AbstractThe critical stress field intensity factor for crack propagation,KIc, was determined for a large number of glass fiber‐reinforced acetal copolymer compositions and for the unfilled resin. The results were interpreted in terms of a model previously proposed for the tensile behavior of these materials. TheKIccould be regarded as a linear function
