The main objective in producing composites is to combine different materials to produce a single device with superior properties to the component unit. The present study used a composite consisting of plaster, cement, EPS, tire, PET and water to build prototype solar attempt to reduce the manufacturing cost of such equipment. It was built two box type solar cookers, a cooler to be cooled by solar energy, a solar dryer and a solar cooker concentration. For these prototypes were discussed the processes of construction and assembly, determination of thermal and mechanical properties, and raising the performance of such solar systems. Were also determined the proportions of the constituents of the composite materials according to specific performance of each prototype designed. This compound proved to be feasible for the manufacture of such equipment, low cost and easy manufacturing and assembly processes / Foi concebido e estudado um comp?sito de matriz cer?mica composto por gesso, cimento, EPS, pneu, PET e ?gua para construir prot?tipos solares competitivos em efici?ncia com outros equipamentos de materiais convencionais j? constru?dos e estudados e de menor custo de fabrica??o. Foram constru?dos dois fornos/fog?es solares tipo caixa, uma caixa t?rmica para ser refrigerada por energia solar, um secador solar e um fog?o solar a concentra??o. Foram determinadas as propor??es dos materiais constituintes do comp?sito em fun??o das especificidades de desempenho de cada prot?tipo projetado e de resultados alcan?ados pelos prot?tipos anteriormente estudados. Foram abordados os processos de constru??o e montagem de tais equipamentos e determinadas propriedades t?rmicas e mec?nicas. Avaliou-se tamb?m o desempenho de cada prot?tipo constru?do. Esse comp?sito mostrou-se vi?vel para fabrica??o de tais equipamentos, com baixo custo e f?ceis processos de fabrica??o e montagem
