“…Many researchers have reported the advantages of employing fibre prestressing method on the mechanical performance of composite materials. 4,6,7,13,14,19,24,[67][68][69][70]77,[80][81][82]85,87,[89][90][91][92][93][94][95][96][97][98][99][100][101][102][103][104][105][106] The scheme shown in Figure 7 illustrates the positive effect of the compressive residual stress existence within the matrix. Applying fibre prestressing method can decrease the generation and propagation of cracks within the matrix by reducing the magnitude of existing tensile residual stresses.…”

This article reviews the literature studies based on improving the mechanical properties of fibre-reinforced composites using fibre-prestressing method. The idea is characterized by pretensioning the fibres either elastically or viscoelastically prior matrix curing. The beginnings of the studies in this field were focused on reducing fibre waviness and breaking the weaker fibres by pretensioning the fibres to a relatively high stress level prior moulding process. In the last three decades, the concept of fibre prestressing had been developed to include its ability to reduce the effect of undesired residual stresses existence accompanying manufacturing process of fibre-reinforced composites. The main advantage of fibre prestressing method is to generate a desired and controlled residual stress state within the matrix in order to obstruct the initiation and propagation of cracks. Various techniques of fibre prestressing have been reviewed to show their scope of applications, developments and limitations. Therefore, the findings drawn from this review can be used for further studies in the field of fibre prestressed composites in order to select the most suitable methodology and develop it to fit the manufacturing process requirements towards a production of high-performance composites without a considerable additional cost.

Das zyklische Spannungs‐Dehnungs‐Verhalten metallischer Faserverbundwerkstoffe am Beispiel von stahlfaserverstärktem Silber und Kupfer

Faserverbundwerkstoffe (FVW) weisen bei schwingender Belastung in Faserrichtung häufig ein Spannungs‐Dehnungs‐Verhalten auf, das nicht unmittelbar aus dem Verhalten der einzelnen Komponenten, sondern nur durch ihr Zusammenwirken im Verbundwerkstoff zu erklären ist. Die auftretenden Effekte können aus den Herstellungsbedingungen der Werkstoffe oder nachfolgenden Wärmebehandlungen resultieren und lassen sich häufig auf innere Spannungen und die Verteilung der Wechsellast auf die Komponenten zurückführen. Einige in Metall‐Metall‐Verbundwerkstoffen (stahlfaserverstärktes Kupfer bzw. Silber) beobachtete Besonderheiten werden diskutiert. Die Abweichungen vom zunächst erwarteten Verhalten können einerseits bei Nichtbeachtung zu vorzeitigen Schädigungen des Verbundwerkstoffs führen, andererseits aber auch in besonderen Fällen zur Optimierung wechselbeanspruchter FVW herangezogen werden.
