Abstract: Transparent panel of acrylic glass (PMMA) having internal reinforcement elements for securing fragments of the acrylic glass formed upon an impact with a foreign body. The reinforcement elements are embedded interspersed within the panel and spaced apart in parallel longitudinally. The reinforcement elements include rigid cables and elastic cables. The rigid cables are formed of a metal having an ultimate tensile strength of at least 500 MPa. The elastic cables are formed of a metal having a percentage elongation (engineering strain at fracture) of at least 30%, preferably between 40% and 80%. The rigid cables and elastic cables may be separate and spaced apart from one another, or intertwined with each other. The panels may be used to form an acoustic barrier.
