“…The results in table (1) shown that the impact strength of the samples immersed in (HCL, KOH) decreased after immersion due to the effect of (HCL, KOH) in breaking the hydrogen bond between polymer chains and interfacial bonds in the interface between fibers and epoxy resin, therefore the composite become more brittle than before immersion. While we notice that the impact strength of the samples immersed in (distilled water, Benzene, Kerosene) increased after immersion because of the hydroxide groups in those solutions making the composite more ductile and can absorb more energy before fracture [12].…”

“…Composite materials are materials which are made by artificially combining two or more components, thus interface are present in a composite material [1].Many composites used today are at the leading edge of materials technology with performance and costs appropriate to ultra demanding applications such as spacecraft. But materials combining the best aspects of dissimilar constituents have been used by nature for million of years [2].…”

Hand lay-up molding is used for preparing sheets of epoxy composites reinforced with chopped strand mat (randomly direction) glass fibers by weight fraction of (44%). The sheets were left to solidify at room temperature (23 ± 2) ˚C. The samples immersed in (HCL, KOH, distilled water, Benzene, and Kerosene) for equal period of time at constant temperature (23± 2) ˚C. The impact and compressive strength were calculated for the samples before and after immersion in different chemical solutions.The results shown that the impact strength of the samples that immersed in (HCL, KOH) solutions were decreased after immersion, while the impact strength of the samples immersed in (distilled water, Benzene, Kerosene) were increased after immersion.The results showed also that the compression strength of the samples immersed in (HCL, KOH, distilled water) decreased after immersion, while the compressive strength of the samples immersed in (Benzene, Kerosene) were increased after immersion. Finally the results showed that the maximum relative mass gain (minimum absorption resistance) was of the samples immersed in (HCL) solution in both impact and compression test. While the minimum relative mass gains (maximum absorption resistance) was of the samples immersed in (KOH) solution in both tests

“…As a widely applied engineering material, polymethyl methacrylate (PMMA) has many excellent properties such as good weathering resistance, high surface hardness, and strength, especially the transparency and durability . However, PMMA often exhibits brittle fracture behaviors at room temperature, which may bring disastrous consequence for the structural application. In order to design the structural components with safety and to prevent the brittle fracture, it is very crucial to well understand the fracture mechanism of PMMA.…”

Polymethyl methacrylate (PMMA) is one of important engineering materials and has been widely applied in various fields. Owing to the catastrophically brittle fracture nature, exploring the fracture mechanism of PMMA is of crucial significance to guide its engineering application. In this work, tensile tests with several kinds of sample geometries including unnotched samples and notch samples with different widths were designed to systematically investigate the macroscopic bifurcation of PMMA. Based on the sufficient experimental evidences, the traditional critical stress intensity criterion was found inappropriate for predicting the macroscopic bifurcation of PMMA. Finally, the fracture features were explicitly clarified based on the detailed experimental observations, and a new explanation to elucidate the fracture mechanism of PMMA was proposed.

This article presents the fracture behavior and applicability of the fictitious crack (FC) model to describe the fracture of a porous poly(methyl methacrylate) material. Two test geometries, wedge‐opening load and single‐edge‐notched beam, were employed under two different test conditions (room temperature and in water at 45 °C); all presented quasibrittle fracture behavior. The crack profile of a wedge‐opening load sample was visualized and measured with the digital image correlation technique. The mechanical response of all the samples, including the crack profile, was successfully modeled with the FC model, and this showed the good applicability of this model to the fracture of this granular poly(methyl methacrylate) material. © 2003 Wiley Periodicals, Inc.
