“…Gaggar et al found that the Izod impact strength is independent of matrix ductility (fracture toughness of resin was not provided) in epoxy/chopped strand fiber laminates. Schrauwen et al compared the falling weight impact test results of woven laminates and stitched laminates made with a brittle UPR and a toughened VER and concluded that the fiber architecture plays a major role in the impact resistance of composites, while the matrix ductility showed no clear effect.…”

The role of nanoparticles in the fracture toughness of glass fiber‐reinforced polyester composites (GFRPs) was investigated. An unsaturated polyester resin (UPR) and a vinyl ester resin (VER) were toughened by two distinct methods: (1) incorporating a very low loading (0.04 wt%) of alkyl or vinyl modified graphene oxide (mGO); or (2) adding core‐shell rubber (CSR, 1 and 5 wt%). For unreinforced resins, results from compact tension tests revealed that adding 0.04 wt% of mGO increased the fracture toughness (GIC_Resin) of UPR and VER by as much as 49 and 35%, respectively, without lowering the modulus and glass transition temperature (Tg); however, the mode I interlaminar fracture toughness (GIC_Comp) of GFRPs was not improved. On the other hand, CSR is a more effective toughener, though at much higher loadings. 1 wt% had little effect, but 5 wt% of CSR enhanced GIC_Resin of UPR and VER by 280 and 600%, respectively, with a significant decrease in flexural modulus and flexural strength. 5 wt% of CSR was not able to increase the GIC_Comp of UPR laminates either; however, CSR did increase the initiation GIC_Comp and propagation GIC_Comp of VER laminates by 50 and 33%, respectively. Scanning electron microscopy of the fractured specimens revealed weak fiber–matrix bonding for all GFRPs. This work suggests that enhancing fiber–matrix bonding is critical to gain the benefit of adding nanoparticles to GFRPs. POLYM. COMPOS., 40:E1512–E1524, 2019. © 2018 Society of Plastics Engineers

“…Table 3, showing data from Grytten (2008), provides very useful information about the different velocity regimes and their corresponding application and test methods. Schrauwen and Peijs (2002) performed an experimental investigation on the influence of the matrix ductility and fiber architecture by implementing repeated impact tests on laminated fiberglass composites. To investigate the penetration energy and development of damage in the composite material, a drop test rig was used while the force was measured using a piezoelectric force transducer.…”

The damage to composite structures caused by impact events is one of the most critical behaviors that inhibit the widespread application of composite material. As the application of synthetic and natural based composite material increases over time, improved knowledge of composite damage in areas such as automotive and aerospace is exceedingly necessary. It is important to study and understand the damage mechanism of composite structures to produce effective designs. The failure caused by damage in structural design can result in unintended consequences. Extensive research has been conducted to detect impact damage in synthetic fiber. There are various methods to identify and characterize the damage. This article provides a comprehensive review of recent literature focusing on the broader scope of impact damage and incipient thermal damage of synthetic and natural fiber-based composites. In this report, the available research is reviewed by considering all aspects related to damage in composite materials, particularly the work done on detecting and characterizing damage mechanisms of synthetic and natural fiber-based composites.

“…It is, e.g., often observed that when comparing woven configurations to unidirectional (UD)‐laminated composites, UD‐laminated composites have a lower interlaminar fracture toughness and can thus by delamination spread the impact energy over a larger volume of the composite with associated increase in penetration impact resistance. [ 15,21 ]…”

Highly Impact‐Resistant Silk Fiber Thermoplastic Composites

Silk fibres combine good stiffness and strength with a very high strain to failure and are as such highly promising to realize composites with high impact resistance. It is shown that to realize this potential it is quite beneficial to employ matrix materials of high strain to failure, particularly thermoplastic matrices. High impact resistance is thus achieved, well above values for the pure matrices. Below the glass transition temperature of the thermoplastic matrix, the impact energy absorption decreases. The adhesion between fibre and matrix also plays a significant role; lower adhesion typically increases the low‐velocity penetration impact resistance, due to the spread of damage. Finally, the fibre architecture is pivotal; when a woven fabric is used which is unbalanced in strength, the impact resistance reduces in correspondence with the weakest material direction. A quasi‐isotropic lay‐up has a lower capacity for deformation than a balanced woven configuration which likely explains the observed lower penetration impact resistance.This article is protected by copyright.
