A comprehensive approach for the analysis and design of pultruded FRP beams in bending is presented. It is shown that the material architecture of pultruded FRP shapes can be efficiently modeled as a layered system. Based on the information provided by the material producers, a detailed procedure is preserited for the computation of fiber volume fraction (V r) of the constituents, including fib...

In this paper, a method of solution and some numerical resu~s of free vibration and buckling of composite laminates are presented. All the edges of the laminates are assumed as simply supported. Ritz's method of solution is used with deflection surface expressed in terms of double series in Chebyshev polynomials satisfying the simply supported laminate boundary conditions. The numerical results...

The use of composite laminate materials has increased rapidly in recent years due to their excellent strength to weight ratio and resistance to corrosion. In the construction of marine vessels, stiffened plates are the most commonly used structural elements, forming the deck, bottom hull, side shells and bulkheads. This paper presents the use of a stochastic approach to the design of stiffened ...

Abstract The wet winding process is an established manufacturing technology for the production of rotationally symmetrical components made fiber‐reinforced plastic (FRP), such as type‐IV hydrogen pressure vessels. In this process, FRP laminate produced by continuously depositing impregnated fiber band on core in a pattern adapted to component stress. Despite long history there are shortcomings ...

This paper enumerates the effectiveness of externally bonded Hybrid Fiber Reinforced Polymers (HyFRP) laminates on reinforced concrete beams for flexural strengthening. A total 5reinforced size 150 x 250 in cross section and length 3000mm were considered this study. All tested four-point bending over a simple span 2800 mm. Of above five beams, one beam served as reference other four HyFRP lamin...

Resistance spot welding is the most economical joining method for production of automotive steel bodies. In modern car body construction, however, its future applicability limited due to growing mix materials in multi-material design. response increasing weight reduction requirements protect environment and natural resources, lightweight materials, fibre-reinforced plastics (FRP) particular, ar...

Abstract Fiberglass-reinforced plastics (FRP) composite materials for ships that are widely used marine-grade unsaturated polyester resin matrix and combimat fiber, a combination of chopped strand mat (CSM) woven roving (WR) fibers. Although less popular than marine CSM–WR, biaxial warp-knitted glass fabrics have the potential to be applied as fiber laminates ship hull materials. A comparative ...
