A significant amount of waste composites is generated each year and the need for a recycling method is becoming a necessity. Environmental Technical Services has developed, with the support of the University of Missouri-St.Louis, a method for recovering valuable constituents from composite materials. The process converts the polymer matrix to lower chain hydrocarbons and fuel gas leaving behind fibres. Mechanical tests of BMC panels, reinforced concrete and compression moulded panels made with recovered fibres were carried out. 10 refs. USA... 

Dynamic fracture (by fatigue) of the composite materials with thermoplastic matrix and reinforced with short fibres In this field, the investigations were devoted to elucidate the polymer and composite materials behaviour under exploitation conditions (non-notched specimens) as well as regarding the crack propagation (notched specimens). In the first place, the attention was focused on the composite materials with thermoreactive matrix, widely used in the automobiles industry. The test results, performed... 

Most biodegradable composites being tested employ a thermoplastic matrix. There are inherent difficulties in interfacial wetting between linear thermoplastics and reinforcing fibres which limit optimum stress transfer between the fibre and matrix. This also deleteriously affects hydrolytic stability [63]. While the use of solid polymer without fibre has been considered [24, 71-73],...
